Radio 4 Brainport Podcast - Prof Jean-Paul Linnartz Interviewed Prof Harald Haas on Where Do We Stand in 2022 on LiFi and Optical Wireless Communications

Jean-Paul Linnartz, Research Fellow at Signify, Professor at the Eindhoven University of Technology and a Radio 4 Brainport reporter, interviewed Professor Harald Haas on where do we stand in 2022 on LiFi technology and Optical Wireless Communications.

Below are some of the Podcast conversations. Some of the conversations have been edited by Chuks from LiFi Tech News:

Jean-Paul Linnartz: “The internet is not always as fast as we would like it to be. But that may not be a problem on the internet, though it may be a problem in the wireless link towards the internet. We are used to doing that via radio communications. But it can be done much faster. And by reusing light, one of the pioneers in that field is none other than the person who launched the term LiFi is Professor Harald. He coined the term quite a couple of years ago. What have you learned since then?”

Prof.Harald Haas: “Thank you. Sure, Paul. And I'm very pleased for the interview. And thanks for that very important equation. So, really, what we wanted to do is with LiFi, we build a similar experience to an end user, like WiFi, or three GPP. But we are using the visible light spectrum and the infrared spectrum, to basically grade bigger data pipes, provide more data, higher data rates, and more secure communication. And, really unlocking the future of wireless communications because there's this spectrum crunch in RF that we're seeing, and there's no new spectrum that's required in the light spectrum, which is able to provide free and unlicensed spectrum to do that. And what we've learned is that LiFi is a technology that solves one major big problem in the area of security. So, LiFi is much more secure than radio communications from a physic layer perspective. That's where the technology at the moment takes up commercially. But what we have learned is that LiFi can really unlock the terabit per second data rates that we are now trying to achieve in 6G.”

Jean-Paul Linnartz: “We have seen very impressive bit rates. I even had a colleague of you say that possibly the wireless optical channel could be faster than the fibre channels. So, possibly the bit rates there are unlimited, you also reach very high bit rates. But I also sometimes think if I want to go through Mumbai congested or through London and a congested moment, I do not need a Ferrari. So, is it really the bitrate only or other other things that are very key and possibly also light is very attractive?”

Prof.Harald Haas: “I think data rate is one key performance indicator there. Obviously others as well, like user experience, you want to have your data in a reliable way and in a secure way, and you want to achieve the connectivity of many devices. So, we have an explosion of devices in a personal sphere, went from one smartphone to maybe now 10s and even 20 of different devices that are attached to a person so, that there's an explosion of devices. So, we need to have both we have higher data rate but also achieve higher density of devices and provide them with reliable data in  RF, it has a problem because RF always spreads the signal out and that if you want to put in more transmitters or access points, you end up in a problem of interference. And that really reduces the lead area capacity in RF but visible light communication, if you imagine a laser pointer and when you're doing your presentations is a very tiny sport. And that idea of tiny sports and containing a signal is something we can leverage really to unlock the number of devices per area with LiFi. And that is an element that is often overlooked when looking at LiFi. If you're not looking on Yeti, it's probably coming from the old view of optical VR as being the sort of the modern, the TV remote control on steroids. But it is not the remote control on steroids. It's a network technology, providing coverage and providing mobility and providing all the things we know in WiFi and cellular. And that's a very important point to be aware of.”

Jean-Paul Linnartz: So, interesting developments down the radio people also make huge progress, they believe they can steer a beam, but that requires a lot of signal processing and many antenna elements. So, the complexity of that technology is increasing a lot. You think of a very simple solution pointing a laser beam?”

Prof.Harald Haas: “We do think in the same vein, it's an inherent feature of using sort of what we call segmented ops. The optics are basically beans. But we are not thinking of steering a beam or putting very expensive optomechanical systems into smartphones. It's really building on the idea of a grid of beams. So, having multiple, multiple lasers if you want that point in slightly different directions. And then you just turn them on when you need an area to be covered and you turn all the others off. But it's done very simply with a simple lens systems in front of the device. So, we don't need a bank of patient a phase shifters, we don't need a bank of power amplifiers. It's the complexity for achieving exactly what Millimetre waves have less to do, and terahertz have to do. We achieve it with a less significant less technical complexity.”

Jean-Paul Linnartz: “And some of that technology is already already entering the smartphones, very tiny lasers to do all kinds of measurements, we see the same in autonomous driving with LIDAR systems. So, there are a number of technological drives that really make that alternative to radio communication mature.”

Prof.Harald Haas: “That's true, I think that's really one of the key points is we have already devices out there commercially deployed, you mentioned LIDAR, it's very important, but also mean every smartphone has face recognition inside every laptop has face recognition, these are lasers these are so called vertical cavity surface emitting lasers, which says that there are buildings that have already user experience. And then we will probably see that the light sensing functionality will enter the smartphone device. And if you ever if this device is there, why don't use it, to also do communications across these devices. Yes, these things are coming into that space. And we are now preparing the grounds to use them in a vise and sensible way to build the ultimate nervous system, plus the sensing capabilities. And if you put sensing capabilities in the nervous system together, you're exactly in a 6G space. And this is exactly where we drive this technology at the moment.”

Jean-Paul Linnartz: “We are very happy to have you here today in Veldhoven, the Metro centre, so we do not have to go to Edinburgh go to straight line. If you look around in this environment and listening to your presentation, you pointed out there is a difference between shooting laser beams between satellites at very impressive bit rates terabits per second. But that is not exactly the same technology as what you named LiFi. Where are the differences?”

Prof.Harald Haas: “And the difference really is the coverage. And like you said, we have free space optics, we have the laser pointer I've mentioned. It's a point to point link, it's very for fixed location, you can’t move the beams, you can’t move the transmitter, you can’t move the receiver, it has to be aligned. And so, in fact, Pima acquisition and tracking systems, very complex devices in these optical links, we want to cover an entire room, we want to cover maybe an entire city at some point, using street lamps and other other devices. And therefore we spread the photons out that means if we have a detector that is tasked to be fast and small, we need to somehow collect all these photons back into the receiver. And the way we do that is where some of the engineering challenges lie. But it is all doable with different opto electronic and optics than elements that exist at the moment. Yeah, it's just putting things together in the correct way.”

Jean-Paul Linnartz: “We don't have that in 4g, we do not have that in 5g. 6g is the opportunity which can go to optical communication. 6g is the moment that we need to go to optical?”

Prof.Harald Haas: “Absolutely, 6g is where optical wireless communications should be playing a major role. I know that many people do about terahertz communications and that's the good thing. The message is that a spectrum crunch really exists. We need more spectrum. And that's that's a given. Whether you do it in a space where there are no devices and where you need another 20 years or 10 or 20 years in order to build the ecosystem or whether you use existing devices. Now that is the big question. But I think it's a strong commercial and scientific argument to say this is now the time to get optic violets kind of communications out into the consumer world into the mass market into the cellular space. It is really where it should be in the building ubiquitous, sorts of nervous systems, in our homes, in our streets, in all our environments, and we are ready for that.”

Jean-Paul Linnartz: “We are ready for that. you're already pushing that you have been pushing that a lot from the UK, you also have many contacts internationally. With California. Now you're in the Brainport region, where are the strengths or the opportunities whereas your competition in the Brainport region?”

Prof.Harald Haas: “I think there is a lot going on. And that's a good sign because that signifies that many companies and many people think and realise the opportunities and it's an ecosystem that we need. And it's never if we build something big, like cellular it's never done by a single company or a single element especially if it's complex like this because you need a complete ecosystem with devices but with transmitters with systems with optics and it's good to see that that that is much do multiple great developments going on and you mentioned KSD, they are building now, laser lighting, which is the next sort of revolution in lighting pay basis based on on blue lasers rather than blue LEDs. But that comes with it again with a great advantage that these devices have a high bandwidth. And we've shown it at CES this year, 100 gigabit per second with a WDM system from these devices. I mean that there's many examples and that where people build parts of the ecosystem, and it comes together. And that's the very important aspect. And that's why I like this conference like this. It brings people together, building an ecosystem.”

Jean-Paul Linnartz: “I heard you talk, let's say 10 years ago about we will have LEDs everywhere, we can modulate the LEDs. But now we see that these LEDs have some limitations, you're moving to lasers. Coming also from a radio environment I sometimes tend to say but listening causes more effort than talking we may see the same in optical wireless communication that leads us are ultimately fast. Here in this presentation, you also said there is something in the detectors in the photodiode. So that is also part of that ecosystem, much more than having a faster laser.”

Prof.Harald Haas: “That is correct, we need to look at the end to end system and transmitters are important. And LEDs, as you say commercially, are designed for lighting and all the efficiencies, the cost of the drivers and so on. And that compromises bandwidth and data rates. That's understood. But the other part of the equation is the receivers have to be flat, because you want to integrate it into mobile devices, at the same time collecting a lot of energy. So, photonic energy around it. And building the architecture for that is but an area which basically has not been looked at that much or less, there's a lot of work in other around the world. But that's an element that has to grow and build practical receivers as well. But with the LEDs, I think you mentioned the limitations, but it's still an option that is providing an indoor connectivity, it is not all about data read, as you say if you look at secure communication in the company you're presenting signify and others and build these products that allow indoor navigation at that at fairly high speeds and also in a secure way.”

Jean-Paul Linnartz: “If I listen to you, as a university professor, and someone who is very active in companies who already do this, there is still a lot to do in terms of research, pure research from the academia Bucha results. So, the time is getting there to really make it happen.”

Prof.Harald Haas: “I think the time is getting there. And I think we are commercially at a stage where LiFi now has entered or moved away from the prototyping from the pilots. And there's been hundreds of pilots around the world where technology has been proven in various environments in an industrial setting, in a defense setting, and so on. But we now see the defence sectors, basically picking up the technology in buying these consumer devices that the company I represent pureLiFi they are selling and it's huge. So it's a commercial reality. Now, it's a question of how to move from this beachhead into the consumer. And that's where there is further development needed. But research is needed. But there's also product solutions for that space out there. At the moment.”

Jean-Paul Linnartz: “It sounds very futuristic, we will communicate via steerable laser beams. But if I remember correctly, there was a time that Philips and other companies launched a CD player, which in essence is a steerable laser beam that reached at very high speed. So, there is also if I continue that line of thought there is a possibility to make it a mass market and to really go down to ultimate cost down for these kinds of devices.”

Prof.Harald Haas: “That is absolutely correct. And that's one of the great examples where you have seen that with optical systems. And if you look at SFPs modules of fibre comes they're also in the sort of $10 region and so on . There are these existing devices out there, there's technologies that we can build steerable laser beams if we wanted, also for optical wireless communications at a low cost. So that's an advantage we should be leveraging.”

Jean-Paul Linnartz: “I still hear the same drive as when you started with pureLiFi modulating the LEDs and now it starts to become the time to really have it in a mass market for 6g and that is all coming up. Thank you very much.”

Prof.Harald Haas: “Thank you very much been delighted to speak to you. Thanks”

Li-Fi Conference 2022

The Li-Fi Conference 2022 Edition was a great success. Li Fi Tech News will very soon write articles on the topics treated at the Conference.

What is LiFi?

LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).

VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.

How does LiFi work?

LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several light bulbs that form a wireless network.

When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.

LiFi Benefits

The primary benefits of LiFi are as follows:

• Security: Provides entirely secure access. Where there is no light there is no data.

• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.

• Localisation: Allows localisation due to the small coverage area of LiFi access point - localisation can be used for very precise asset tracking.

• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.

Photonic Networks Experts Prof. Volker Jungnickel & Dr. Christoph Kottke Interviewed by InnoVisions on LiFi Technology

Last week, Prof. Dr. Volker Jungnickel and Dr. Christoph Kottke from Fraunhofer HHI were interviewed and asked hard questions by InnoVisions on LiFi.

ELIoT has shown that the underlying technologies are ready for commercial application. But what is still missing is a significant increase in awareness of the technology and the interest of the target groups that goes with it.

Reliability, low latency and bandwidths up to the gigabit range: these are the technological triad without which the Internet of Things cannot function satisfactorily. But what to do if 5G and WLAN on site do not provide the required performance? Will electronic devices and control systems then remain cut off from the Internet? Prof. Dr. Volker Jungnickel and Dr. Christoph Kottke from Fraunhofer HHI explain why and how it is possible to close these connection gaps with light.

Question 1: Almost all of us have tried Morse code with a flashlight and have found that this method is both tedious and extremely error-prone. You use the same basic principle in research into optical wireless communication at the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute HHI. But you claim that you can use it to outshine wireless solutions such as 5G and WLAN?

Jungnickel: “We don't just claim that, we have also proven it long ago. In fact, our Light Fidelity (LiFi) communication network is based on the simple principle of turning an LED or laser on and off very quickly. In contrast to Morse code, however, this is controlled by the latest digital technologies, so that the on/off processes can be controlled at extremely high speed and with absolute precision. With this technology and our transmitter/receiver modules, we can achieve transmissions with a data rate in the gigabit/s range, even with a simple setup with a ceiling light and the laptop on the desk. The only condition is a clear line of sight between them.”

Question 2: However, a WLAN network also offers comparable bandwidths. And that everywhere in the room - even without visual contact with the transmitting antenna. So, what is the advantage of LiFi?

Kottke: “Of course you can also establish broadband connections via WLAN. At least, as long as the number of access points and users is limited. Things look different in a training room, a workspace or a classroom: Here, the bandwidth of the radio network has to be shared among many people. Data-intensive applications are then hardly possible for the individual. You block each other. With LiFi, on the other hand, a separate gigabit connection can be easily set up for each workstation. And you solve the problem of an unobstructed view by distributing as many communication modules over the ceiling surface that line of sight is always possible.”

Jungnickel: “And the optical interface has other advantages: in terms of susceptibility to faults and data security, for example. If a robot in industry is controlled with light via LiFi, connection problems caused by interference with wireless connections working in parallel in its environment are ruled out. In addition, due to the system, it is not possible for a malicious jammer to attempt interference, nor for unnoticed hacking in, for example from the next room. Wireless networks are much more vulnerable in this regard.”

Nevertheless, LiFi networks are still hard to find in offices and industrial environments...

Jungnickel: “But that could change fundamentally in the next few years. The ELIoT project, funded by the European Commission, has key prerequisites for this. In this project, we have developed the LiFi technologies together with international partners from research and industry into a system concept that can be used for a wide variety of requirements and areas of application. And that works seamlessly with wireless and cable-based networks of all kinds. To do this, however, we had to ensure that all functionalities could be provided via a chipset. We have also integrated new procedures for the handover: You can now move from one LiFi spot to the next without losing your data connection. And when the connected IoT object leaves the LiFi environment, a seamless transition to a WiFi or cellular connection is possible.” 

Kottke: “ELIoT provided us with important insights and inputs to establish internationally valid standards for the technology. All in all, LiFi has now reached a development stage that is no longer limited to individual, highly specific special applications, but is ready for the mass market. The ELIoT demonstrators that we have set up together with our project partners demonstrate how diverse the potential of optical wireless communication in the Internet of Things is.”

Question 3: These options include, for example, equipping training rooms or controlling industrial robots?

Kotke: “This is by far not everything. For example, think of the data connection of driverless transport vehicles in a logistics centre. They are seamlessly connected to their data centre via LiFi modules in the hall lighting. The LiFi installation itself can also be carried out wirelessly - via a line of sight from one module to the next. This enables quick reconfiguration, for example when the production environment or processes change. In addition, the optical interfaces can offer a special, additional feature for the operation of this Automated Guided Vehicle (AGV): Reliable and highly accurate position detection. Because the light signals propagate mainly directly along the line of sight, our newly developed LiFi positioning achieves an accuracy in the centimetre range. With a radio system, on the other hand, the waves spread mainly via detours and reflections in the room. Moving objects can be located using it in a correspondingly more complex and less precise manner.”

Jungnickel: “One of our demonstrators is addressing something completely different: A LiFi solution for the hotel industry is used here, in which guests can transfer the code to open the room door from their smartphone screen to the electronic lock. And in recreation rooms, from lounges to shopping malls, optical interfaces wirelessly supply information and entertainment screens with changing content. This is not only convenient, it also protects the WLAN, which can now be used entirely for other purposes.”

Question 4: So, your system is another connection option for indoor use in trade and industry, which should usually work in parallel with the WLAN?

Jungnickel: “Not only that. Our project partners are also testing optical wireless communication, for example in the area of ​​broadband expansion. It should therefore be a cost-effective and powerful option in the wireless-to-the-home sector. LiFi closes the profitability gap over the last mile, or the last few meters, from the fibre optic or 5G infrastructure to a small radio cell or into buildings and apartments. From the lamppost on the sidewalk, the LiFi module provides the broadband connection through a window to its counterpart in the house or apartment. In many cases, a closed window is an unbridgeable barrier for wireless systems. But not for light. And the owners can save themselves the laying of a cable on their property.”  

Kottke: “Inside the house, the Internet then reaches the living room TV, the home office, the basement and up to the roof via light, for example in combination with Powerline LiFi adapters. This is also one of the scenarios that have already been implemented in live operation in an ElioT demonstration.”

Question 5: Nevertheless, functioning demonstrators pave the way towards the mass market. Are you still a long way from reaching your goal?

Kottke: “That's not necessarily our job as researchers either: ELIoT has shown that the basic technologies are ready for commercial application. But what is still missing is a significant increase in awareness of the technology and the interest of the target groups that goes with it. ELIoT has brought together strong industrial partners within the consortium and beyond, who are now continuing on this path to establish LiFi in a wide variety of areas. We will continue to support them in this.” 

Jungnickel : “The developments through the Internet of Things have only just begun. Wireless communication is an indispensable basis for this. However, wireless systems, including the latest developments in 5G and the next generation of mobile communications, are reaching their limits in many areas. Frequency jungle and disturbing interference are difficult to control when more and more IoT objects in buildings or outdoors should and must communicate reliably with the Internet and with each other. It is all the more important to be able to use different systems that can exploit their advantages appropriately depending on the situation. Data transmission with light is therefore a very sensible and efficient expansion of the usable technology portfolio for the Internet of Things. 5G, 6G, WiFi and LiFi are not competitors, they complement each other.”

ELIoT

As stated on their website, ELIoT is an EU Horizon 2020 project. It is led by the Fraunhofer Heinrich Hertz Institute. The central aim of the project is the development of mass-market Internet of Things (IoT) solutions using LiFi, a next-generation wireless communication network, that travels over light instead of radio waves. With LiFi, the ELIoT consortium will explore a networked wireless communication technology operating in the previously unused light spectrum, besides WiFi and cellular radio.

ELIoT has started in 2019 as a project funded by the EU’s biggest Research and Innovation programme, Horizon 2020. This programme promises more breakthroughs by taking great ideas from lab to the market. ELIoT receives €6 million funding from the Public-Private Partnership ‘Photonics21’ and is formed by the partners Signify (formerly Philips Lighting), Nokia, MaxLinear, Deutsche Telekom, KPN, Weidmüller, LightBee, the University of Oxford, Eindhoven Technical University and the two Fraunhofer Institutes; Heinrich Hertz Institute and FOKUS. Even more, companies will shortly be added to the consortium as associated partners.

Li-Fi Conference 2022

The Li-Fi Conference 2022 Edition was a great success. Li Fi Tech News will very soon write articles on the topics treated at the Conference.

What is LiFi?

LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).

VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.

How does LiFi work?

LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several light bulbs that form a wireless network.

When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.

LiFi Benefits

The primary benefits of LiFi are as follows:

• Security: Provides entirely secure access. Where there is no light there is no data.

• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.

• Localisation: Allows localisation due to the small coverage area of LiFi access point - localisation can be used for very precise asset tracking.

• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.

Installation of Li-Fi GigaDock® of Fraunhofer Institute for Photonic Microsystems IPMS On The ISS Space Station

The Fraunhofer Institute for Photonic Microsystems (IPMS) released a press statement on its website on Monday 07th November. They have developed a LiFi transceiver that guarantees data transfer between the components. This was integrated into the iBOSS GmbH interface and has been on board the ISS (International Space Station) for testing purposes since February 2022.

In order to be able to flexibly attach and detach modules directly in space, easy-to-couple and standardized components are particularly important. In addition to the mechanical coupling of the individual modules, it is essentially a matter of ensuring the transfer of data and energy between the individual modules so that satellites can be combined as required. For this reason, RWTH Aachen University applied for a patent years ago, which has now been brought to market by the spin-off iBOSS GmbH as iSSI® (intelligent Space System Interface) and forms a standard interface for such systems.

Part of the interface is a development of Fraunhofer IPMS and also known as Li-Fi GigaDock®. The core of the technology is an optical wireless transceiver, a highly integrated device that enables contactless full-duplex and bidirectional data transmission with a data rate of up to 5 Gbps. The possible transmission distance of the optical data interface is five centimetres. The component can also be used for rotor-to-stator transmission, as the transceiver functions perfectly even at high speeds.

"Building on this component, Fraunhofer IPMS has developed a communication module for iBOSS that has now made it into space, or to be more precise, even onto the ISS," says a delighted Alexander Noack, head of development for optical wireless communication. "In addition to space travel, the component can be found in industrial communication systems, in medical technology as well as in docking applications," he continues.

In February, the interface flew into space for testing and demonstration purposes and was mounted by a robot for the first time on the Japanese part of the ISS. The module is to remain there until mid-December and prove its operational capability under vacuum conditions and the influence of radiation.

Interested parties can find out more about the technology at the Electronica trade fair in Munich from November 15 - 18, 2022. Fraunhofer IPMS will exhibit its LiFi developments in hall B4 (booth B4.258).

OWNii Coin (LiFi Cryptocurrency) Updates And Highlights From A Recent OWNii Twitter Space Podcast

OWNii Coin (LiFi Cryptocurrency) Updates And Highlights From A Recent OWNii Twitter Space Podcast

The CEO of the OWNii Token, Mr Ken Peterson, conducted an AMA (Ask Me Anything) twitter podcast on Sunday 23rd October 2022. Prior to this, questions were sent to the OWNii team and Mr Ken went through the questions during the podcast. Roger Williams, CEO of Mobile Blockchain Solutions was also in attendance. During the podcast, Mr Ken Peterson released some interesting updates about the OWNii coin while going through the questions.

Below are some of the Podcast conversations about OWNii and LiFi. Some of the conversations have been edited by Chuks from LiFi Tech News::

Roger Williams: “Hi, I'm Roger Williams, and I am the CEO, and founder of mobile blockchain solutions. Currently, we are partnered with Mr. Ken Peterson to help deliver the OWNii token as right now we are in a rebuilding mode, we decided that having this on board would be a different situation and just a better situation for our users to get a supreme experience. And so, what Mr Ken wanted to do was to rebrand the token and, and make sure that all the components of his vision for OWNii would bring to the community and LiFi, and be able to live by the world. So, that's why we were brought in to help rebrand and help get the token offering service going in. Right now, we're currently in the process of getting ready for private sale, and the launch of the token.”

Mr Ken Peterson: “Okay, I appreciate that. Quick summary, guys, he does a lot more than that. But that's kind of like the elevator speech. And I appreciate him, kind of letting you know, the more technical stuff, you probably wouldn't be able to grasp it because it's our back office stuff. But at the end of the day, he is the person and his group has got to be responsible for the launch, which we're pretty close to doing. But they had to come in and fix some things. So, I'm just going to go over the questions right now I'm gonna jump into it. The way we're going to do it here is that I'm going to read all the questions that were sent to me, given by the person's first name, and then I'm gonna give the answer to that question. And then the last portion of it is going to be a summary as to what we're going to do next.”

 
Mr Ken Peterson: “Next Question. How many companies or households have been using this technology successfully? The answer to that is, right now, LiFi is in beta testing mode. A lot of companies are developing end-user products for the technology as soon as LiFi is available. That's why we have developed the coin because the coin will actually help us with the infrastructure and the LiFi equipment.”

“LiFi is faster than WiFi because LiFi uses light to transmit data, as opposed to WiFi using radio waves. LiFi is also more secure and does not allow the information to be hacked. Because light doesn't travel through walls.”

Mr Ken Peterson: “A fourth question was, what do you expect your first year earnings to look like, for selling this technology? This young lady must be a salesperson because she's dead on the sales portion of it. My answer to that is first LiFi city said is expected to generate sales of $15 million the first year, but the coin is not figured into that equation.”

Mr Ken Peterson: “Next question, what makes this coin different from the others? Okay, here we go. This is an asset-backed with technology coin just designed to create revenue through internet service providers. We are an Internet service provider. And we are licenced in all 50 states. Because the coin raises funds for the infrastructure. Each time, we installed into a new area, we raised the value of the coin. And because some of the funds goes back into the coin, the value goes up. And that's just a layman's explanation. But, you guys will get more information on this when we're ready to go public.”

“The next question is, when will the coin go public? Okay, this coin will go public very soon. The issue has always been the installation of the LiFi internet. We want to actually install in our first city, and our first city is scheduled to launch here in the United States real soon.”

Mr Ken Peterson: “What is the current value of the coin? Right now, the coin is valued at 25 cents, and it's being offered to our seasoned people for 50 cents on a website that is entitled private.ownii.net.”

Mr Ken Peterson: “How soon will the investment reimbursement take place? My answer is I can tell by your statement, you are frustrated, which is the reason for this podcast. I feel that because of time restraints, to have a live broadcast would get too lengthy. And I want to answer everybody's questions with complete transparency, and not have a back-and-forth for obvious reasons. The time is not productive, and would not be fair to the other people on this podcast for them to hear this sort of bickering when I want to share good and positive news.”

“This is not your typical coin. There are more than 8000 coins on the exchange and none of them have the capability that OWNii has. We have a utility coin that would generate revenue with the new LiFi Internet, and that's the direction that we have always been.”

“If you're unhappy with what you did, with your purchases, all you have to do is request your money back. And I will return it to you.”

Mr Ken Peterson: “I'm interested in knowing how LiFi technology can be useful in green and sustainability, health. And, well, smart homes. Great question. LiFi is the internet through light. Light is safe and secure and green because it transmits data at the speed of light. The Smart Green City needs to operate at that speed and WiFi will not sustain the bandwidth to accomplish the goal. 5G has already been identified as unhealthy, and LiFi operates at 4G.”  

Roger Williams: “We've launched the new ownii.net website. We're also in preparation for the private sale which will be happening between now and the end of the year. There will be a communication email coming that will let you know when we will launch the actual private sale. And then we're going to go to presale, next. And then after presale, we will go public and then we'll be on a big exchange. So, right between now and the end of the year, the private sale will actually be started.”

Roger Williams: “So, the new OWNii website is up any information on what is going to be happening, you'll be able to get an update on the email. If there's any issues, you can hit the contact section on the OWNii website. And we will have a message and we'll respond back as well from there. So, once we launched the actual tokens, they'll go straight into your trust wallet, and we'll be able to send them there. So, we're going to set the blockchain team is working on getting all that stuff together and organising it and we're also going to be working on helping Mr. Ken on getting out better communications.”

Mr Ken Peterson: “Last question is when is the release date for the coin? And the answer is the release date is pending on the release date of the first LiFi city. And that is something that we're going to publicise the LiFi city release date here real soon. Like I said, we just don't want to step ahead of the contract that we have on that, because this is a huge opportunity, guys, we got three cities that we're getting ready to launch. And we want don't really want to put the information out there too eagerly.”

OWNii Coin

OWNii stands for Optical Wireless Network Internet Infrastructure.  OWNii Coin is developed to oversee, develop, and design the physical infrastructure necessary to implement LiFi in the United States and other nations on a global scale.

OWNii creates wireless communication that is faster, addresses issues with internet security, and allows localisation due to the small coverage area of LiFi access points used for precise asset tracking. Furthermore, providing ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.

The OWNii Ecosystem is well-positioned to achieve that, and in the process of its overall development plans, achieve the very much-needed balance between the demand for speed, capacity, data throughput, security, sustainability and growth-related issues.

Highlights from the Podcast

We picked a few highlights of the recent OWNii Token Twitter Podcast:

1) The OWNii coin is an asset-backed with technology coin designed to create a revenue through internet service providers.

2) The redesign of the OWNii website is completed. The website address is ownii.net

3) The OWNii team will make an announcement of the release date of the first LiFi city in the United States very soon.

4) The OWNii private sale for the public will be announced soon.

5) The public launch of the OWNii coin will go ahead sometime after the implementation of the first LiFi city.

6) For those who have already invested in the coin and would like a refund of their investment, they can contact Mr Ken and the OWNii team.

Revisiting The Getac Podcast All Things Rugged with pureLiFi - Episode 007: The Internet at The Speed of Light - Part 2

Revisiting The Getac Podcast All Things Rugged with pureLiFi - Episode 007: The Internet at The Speed of Light - Part 2

In our previous article, we discussed and pick some of the statements said on the part 1 episode of the Getac podcast about LiFi technology. Alistair Banham, CEO of pureLiFi, and Bill Galione, Senior Vice President of Global Sales at pureLiFi Ltd, were invited as guest speakers for a two-part episode on The Getac Podcast All Things Rugged. MarcReece was the host of the podcast. Randy Pfeifer, Wireless Strategist at Getac, was also in attendance and gave his contributions about LiFi technology.

The Getac Podcast covers everything you need to know about rugged computing solutions in an enterprise environment. Each episode features industry thought leaders and rugged solution providers discussing industry challenges, mobile computing, vertical use cases, and comprehensive rugged computing solutions.

In this part 2 podcast episode, they continue their conversation about what they consider LiFi technology as a game changer in wireless connectivity. pureLiFi is one of the companies that are bringing this next generation of wireless communications to the market.

Below are some of the conversations of the podcast about LiFi technology. Some of the conversations have been edited by LiFi Tech News:

Alistair Banham: “Well, I think I think it's very important to recognise that the light spectrum is the largest, it's larger than the RF spectrum, and therefore will provide the opportunity to really drive higher bandwidth data. So, we see the LiFi working alongside the RF technologies, 5g, WiFi and other RF technologies. And we see that being kind of the bearer for the larger data, data information that's going to be transmitted. And then we see, you know, WiFi, supporting the maybe the lower data content, information. And overall, what will happen is, the end user will have an improved quality of experience. So, LiFi actually helps when working alongside those RF technologies to improve the quality of service and the experience for the user of the device.”

Alistair Banham: “So, you know, one of the key things we did when we started on this LiFi journey was to look at standardisation. The standardisation is extremely important if you want to get full interoperability between not only different technologies like RF and light but also between different manufacturers' devices, so people can, you know, interact and work off and alongside other products which are LiFi-enabled. So, what pureLiFi I did, we kicked off the topic interest group with the 802.11bb standardisation body. And, you know, back in 2018, you know, we were very fortunate to get the 802.11bb, which is the first light communication standard aligned to the 802.11 protocol, which by the way is the most pervasive protocol on this planet, all of our connected devices are 802.11 driven. And what that means is that you can start connecting LiFi into everyday connected devices, whether it be your smartphone, whether it be your TV, whether it be your soundbar, whether it be your ruggedised tablet, whether it be your, your consumer, tablet, your digital watch, or your GPS, all these devices, use 802.11 baseband devices and LiFi can connect directly to those. So, really, it supports the vision of full interoperability with WiFi and other RF technologies. And what it does is it allows, you know, current silicon vendors of the baseband devices to really exploit the full potential of their baseman's technologies with antennas that are fast, secure and congestion free. And what it does is you can have an RF and an RF signal being transmitted sitting alongside a LiFi antenna. So, both worlds are supported with the standardisation which is been driven by 802.11bb.”

Alistair Banham: “So, I think the goal for LiFi is not to replace RF technologies.  With RF technologies as super technologies and the clear use cases where RF will be used and can be used, we see it complementary and additive. But also, what we're finding now is that there are multiple use cases arising and, you know, Bill will cover some of these later, where LiFi really stands out on his own, because you're not allowed to use RF with an electromagnetic footprint in those areas. So, no, it's not going to replace it's going to be complementary and additive. But actually, the user's overall experience will go up by using both of these technologies together.”

Randy Pfeifer: “Sure. So, in mid-2018, our Getac UK office engaged with pureLiFi, to learn more about the technology. So, we liked a lot of the attributes of the technology, high level of security being probably prominent in that space, we decided to take on and look at integrating that technology into what at that time was called our tablet that is evolved into our UX10, which is a 10-inch Windows-based tablet, and in to showcase some of that technology. I do want to take a moment though, to thank pureLiFi for their innovations around this technology and Professor Harold Haas for his innovations in this space. So, Getac loves to stay on the leading edge of any wireless technology in this space. And we took this on and the UK office quickly adopted it into the US markets for US Army to demonstrate some of this capability. And we were able to gain a lot of ground and a lot of traction with the US Army in the spaces of pop-up command centres, for example. So, we'll talk about that here in a moment. But what's important is that the differences between or the comparisons of LiFi technology against WiFi or cellular is that it can be used in a very quick means of popping up communications, whether it be in command centres or boardrooms or whatever the use case might lead into. It's as easy as moving from when we think about the light and the communications moving from incandescent light to fluorescent light to LED light. That's been the evolution. But as we moved into LED, that's when the light by technology really could adapt and provide some better communication infrastructures. And with built-in security around the ability to not have it no eavesdropping. It can't be hacked, the various frequencies of light, whether it be red, blue, green, and so on, separated in the communications that really interested us in providing a value add to not only the Getac product line, but certainly in the LiFi technology itself in its secure nature that it can provide. And then lastly, the geolocation for safety and security, whether that be in any space of the federal government, the enterprise space, the utility space, we can provide that information from a secure point of view, almost like you would separate it in a private network or in VLANs. So, it's all about being able to separate that traffic and provide that high level of security.”

Alistair Banham: “Yeah, I mean, that's a really great question, Mark. And, you know, just reflecting back on, you know, the early years when I was working with the company on this technology, you know, it wasn't mature enough at that time, we were just developing and, you know, providing first demonstrable solutions for customers to evaluate. And the interesting thing here is that as you started to, you know, to talk to customers about the technology, you know, security, clearly, you know, the fact that you're in a cone, you go outside the cone, it can't be jammed, and all these kinds of great things was beginning to really take shape. So, we had lots of potential areas across multiple sorts of market verticals that were considering, well, how do we use this stuff, and not all of them knew how they were going to use it. But I think as the technologies evolved, it's matured, and, you know, I'm really, really happy to say that our technology is leading. And we have good mature products, and we have a great roadmap of other products that come through the system, you're starting to focus now on, you know, key markets that will really drive revenues, and adoption for the business. And as with most new technologies, they do follow the adoption curve, which is the traditional adoption curve, which is starting in defence, defence adopts it then starts to get a new, new area in manufacturing or enterprise. And then it walks its way through towards touching everyone in the home in the consumer, which is where we all want to be. So, I think where we are today is where we've expanded over time, as we're now very focused on this whole defence market. And there's manufacturing environment, which is the, I think there's going to be the next big beachhead for this technology. But in parallel, we're working to demonstrate how this can work in the home and touch everyone on this planet as we go forward. So, I think, you know, from a broad base of activity, we're now narrowing down to some very key focused areas to deliver this great technology.”

Alistair Banham: “So, you know, what we did at Mobile World Congress this year, was to launch the LiFi home ecosystem. And the whole point of that was to demonstrate to everyone that LiFi can be used in the home. So, we had a new downlighter, we, we connected that downlighter to, you know, a head-to-head mounted display, we connected to our integrated phones, we connected it to a whole series of devices. And very importantly, we demonstrated that you don't need to dig holes in your walls, to you know, put cables in like cat or, or Power over Ethernet to deploy LiFi, the home, we showed that you could use it to your existing wiring in the house that you have today. So, we're on that journey now, where we're beginning to develop these products, and we have them out there being demonstrated and evaluated by customers. And you know, people come to us for, you know, further discussions and evaluation around the home environment. But of course, today we're really focused on our, you know, our beachhead market, which is the defence and moving into the manufacturing environment.”

Bill Galione: “Yeah, there are, there seems like there's an endless number of use cases, we have discussions with customers virtually every week about new industries, new applications, new use cases, and pretty much anybody who can take advantage of the benefits we've been talking about, you know, in terms of interference, free communication, highly reliable, high data rate, excellent user experience is going to be very interested in LiFi and they are, but we as Alistair said, have to narrow down our focus. Initially, our focus has been government in general and defence in particular. And there are some interesting use cases in defence, the one that Randy mentioned briefly, that really brings value by using LiFi as a tactical operations centre, in say, a war zone for our warfighters who might be in a tent environment and need to have wireless communication, but certainly don't want to have any em synergy signature, they don't want to use RF technology. So, LiFi is perfect for that. Very, very secure one. We say that LiFi saves missions and saves lives. And that is very true. And it's not just us saying is the end customer saying it. So, what better value proposition could you possibly have than saving missions and saving lives for our defence, but it goes beyond that, in terms of the Tactical Operations Centre application, there's another value that LiFi brings, for instance, if you're going to have a hard-wired Ethernet connection, which is typically what they have been doing up until now, there's about five times as much cabling required to get that set up. And it's a very complex setup. So, five times as much cabling, and that cabling is generally not recoverable or reusable. Because when the defence people go from one location to another, they'll typically leave that cabling behind them. That's not the case with LiFi. LiFi is very simple to set up, fast to set up faster tends to take down. And you know, the cabling is a minimum amount of cabling, and it's recoverable and reusable. And there are also logistical advantages for that particular use case where you don't really have to have an expert there and an IT guy on site, getting it set up, the guys on the ground can get it set up, they can do it no expertise required and therefore fewer people. So, the value proposition is really clear there for that Tactical Operations Centre. You know, it's a life-saving application mission-saving application. There are economic advantages, and there are logistical advantages there. As we evolve this defence business, there is Alistair refers to it briefly. There's an adjacent market that's emerging, and that is secure manufacturing. So if there's the manufacturing of a classified system in a classified environment, you can't use WiFi or WiFi there either. You know, RF is just not applicable in such a classified environment. So, the obvious answer is LiFi. And in those manufacturing environments, typically, AR is used. So, augmented reality with a Getac tablet, or a head-mounted display is used. And one of the things that LiFi does best is low latency. Low Latency is essential for AR-type applications. So, we see this as an emerging adjacent market, building on the strength that we have in defence, to build a whole new market. So that's one use case is defence. It was already mentioned, the enterprise is another interesting and evolving and growing market for us. Of course, data confidentiality of data is everything. So, secure boardrooms, secure conference rooms, we read in the paper all the time about data breaches, while security is really, really important in these kinds of environments. Light doesn't penetrate walls, it's highly secure, and we can reduce the number of attack vectors. And this is getting a lot of good traction within the enterprise. There are other applications in enterprise that are interesting, and secure access, be it physical or logical access, and access to information is only available via LiFi to certain people in certain locations. Other enterprise things like secure design centres, as we already mentioned, secure manufacturing, and inventory control, there's just many, many new use cases emerging within the enterprise. So, that's another use case that we're focused on.”

Marc Reece: “Yeah, so, let me ask you a question. Because I keep hearing us it's the security and it can't be hacked. And I like to find out a little bit more about that kind of experiment that why can't it be hacked?”

Bill Galione: “We agree it's an exciting market. The third one that we think there's a case to be made for LiFi is, for instance in utilities and We work with our partner Getac there, you guys have experienced in there, we're just getting our feet wet in terms of those types of opportunities and utilities. And the two use cases there, which we think are particularly interesting are kind of industrial IoT applications. So, think about predictive maintenance, where, you know, we've done this in the past to where a LiFi-enabled sensor gathers data in a nasty, harsh, congested environment to transmit information back in terms of when a particular piece of equipment might need to be serviced. So, LiFi, and it's very confidential and secure as well. LiFi is very, very well suited for that application. And then maintenance. In general, we talk about the connected maintainer, this maintainer maintenance person might be carrying around a Getac tablet, and he or she may have a head-mounted display back to this AR play again, where the maintenance function utilises augmented reality. And back to the low latency, high security, low latency aspects of LiFi. It's perfect for that application. So, we see utilities as another interesting market and maybe oil and gas after that one.”

Randy Pfeifer: “Sure. No, you know, on the defence side, I think Bill really nailed it on the head. And that's one of the key elements that we realised and recognised early on. And that was these pop-up tactical command centres, how quickly it is to assemble and disassemble these, I'm right on the right point, all you need is power, and a little bit of backhaul. But basically, the inside of those command centres, whether it be a tent or other facilities, the security of that technology is you know, within the walls of that building. So, that was huge. When it moved to the enterprise space, he touched on the executive conference rooms, and it's all about making sure that as you walk into that room, there's you're instantly connected, that room is the only one that has that connectivity. And we can separate that traffic, you know, as we said, light by colour, or it could be just that conference room in particular, but it's all about trying to mitigate WiFi contention, because every enterprise that I think we can walk into today has WiFi in it, and there is no contention between LiFi and WiFi. So, they can coexist, we can separate the traffic, we can have, you know, provide a very secure environment for those types of environments. Manufacturing was also our other one. And although Bill mentioned that as well, the manufacturing side of this is, is probably one of our second-largest enterprise sectors. And we see that when we're working with, you know, large companies that have whether you're manufacturing or you're doing repairs, we can separate that traffic based on the use cases. And then last but not least, you know, utilities, I think there are a couple of other use cases that really come into play here. And that is Network Operation centres or knocks for the utilities and telecommunications side of things. There's a lot of proprietary data that has to be contained within those knocks, and having LiFi technology in that environment is perfect. And then similarly in the CEOs or central offices of telecommunications companies, or in the device monitoring or IoT monitoring space, it's all about making sure that we're having WiFi avoidance, or coexisting with LiFi, because that is a technology that is prominent in those both of those spaces. So, we see the use cases across these three and other sectors as being a more of a coexistence of WiFi technology or with it. And then, of course, providing that high level of security in all of those environments.”

Li-Fi Conference 2022

The Li-Fi Conference 2022 Edition was a great success. Li Fi Tech News will very soon write articles on the topics treated at the Conference.

What is LiFi?

LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).

VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.

How does LiFi work?

LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several light bulbs that form a wireless network.

When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.

LiFi Benefits

The primary benefits of LiFi are as follows:

• Security: Provides entirely secure access. Where there is no light there is no data.

• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.

• Localisation: Allows localisation due to the small coverage area of LiFi access point - localisation can be used for very precise asset tracking.

• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.

Revisiting The Getac Podcast All Things Rugged with pureLiFi - Episode 006: The Internet at The Speed of Light - Part 1

Credit to Getac

A few months ago, Alistair Banham, CEO of pureLiFi, and Bill Galione, Senior Vice President of Global Sales at pureLiFi Ltd, were invited as guest speakers for a two-part episode on The Getac Podcast All Things Rugged. The Getac Podcast covers everything you need to know about rugged computing solutions in an enterprise environment. Each episode features industry thought leaders and rugged solution providers discussing industry challenges, mobile computing, vertical use cases, and comprehensive rugged computing solutions.

In this podcast episode, they discussed what they consider LiFi technology as a game changer in wireless connectivity. pureLiFi is one of the companies that are bringing this next generation of wireless communications to the market.

Below are some of the conversations of the podcast about LiFi technology. Some of the conversations have been edited by LiFi Tech News:

Alistair Banham: “Okay, so it's really great to be here with you today. So, what is LiFi? LiFi is a wireless communication that uses light, the light spectrum. So, it's complementary in addition to RF technologies. But as I said, it uses the light spectrum to transmit and receive data. It's fully mobile and fully networked, so you can move from one access point to another. And you can access, download, and upload information through the internet. I think one of the key messages I want to get is that LiFi helped solve some of the biggest challenges that we face today with RF.”

“The more downloads and uploads that are being actioned using the RF technology, the poorer the quality of service and the quality of experience for the user. And that is because bandwidth is being stolen by the device that is pulling down the largest data file. So, if you're working, if you're trying to download a, you know, Netflix, film, or project, everyone else in the house will suffer as a result of you pulling that down. Why? Because you're stealing the bandwidth away from those other users and their quality of service goes down. Therefore, the reliability is intermittent. It's not consistent in using RF technologies, but LiFi solves those problems.”

Alistair Banham: “So, the access point will deliver what it's designed to deliver. So, you can design them for, you know, low data rates, median data rates and high data rates. And that's the beauty of LiFi solutions. So, today, we have access points that run at 250 megabits per second, and we have some that run at lower megabits per second. So, it's all about the design.  So, you can design it to support different data rates.”

Alistair Banham: “So, think what it is light is turned into data via super-fast pulses. So, you know, when you take the LED light, we put a, you know, a, an electrical current through that, it will pulse and that will transmit the data that we pick up and receive with our devices. But the most important thing there is, these are not perceivable to the human eye, you know, the light used can be visible light, you know, it's the same as the LED lights we use in our homes, or it can be invisible lights, such as infrared. And what it does is LiFi turns light sources into access points, or APs, as we call them, which don't have to be traditional lighting. So, it could be in the ceiling, it could be a box on the wall, it could be you know something on your desk. I think very importantly, it's fully mobile. So, you can move from one access point to another and stay connected.”

Alistair Banham: “So, then if you're under an access point, and remember the access point will have a cone, a cone in which the data is being transmitted. So, for example, some of our products have a 60-degree cone. So, the 60 delegate-degree cone comes from the access point. And then if you are sitting within that cone, then you can access and transmit and receive data through that access point. So, if you're one of my colleagues, and we're under that cone, yes, we can both access the internet via that access point. If you are someone who is not part of the family or the team, I can say hey, what are you doing in my cone, therefore I know that you're trying to access data within my zone.”

Alistair Banham: “You know, you can set the protocols so that you know using different wavelengths, for example, you know, red or blue or green. You can set one of these to be accessible to different types of individuals. So, a good example would be If an employee of a company could be accessing their internet data via the green wavelength, guests who come into the company could be accessing data through the green, and you know, you could have the emergency services could be accessing data through the red. So, you can programme the technology and use different wavelengths to enable different people to, you know, access data through, you know, light into the internet.”

Bill Galione: “Really, it's really hard to imagine an industry that wouldn't benefit from LiFi, you know, in particular, those that are concerned with secure reliable communications, as Alistair mentioned. And we're kind of on a very exciting journey right now. And it's kind of a typical adoption journey where a new disruptive, innovative technology starts out in Government and Defence where we have a very strong relationship.”

“And then, we see another interesting industry that might be ripe to adapt LiFi technology. And that's the energy industry in general, and in particular, oil and gas. They're also RF averse, these are very congested, noisy environments, which would benefit from LiFi.”

Bill Galione: “So, the point that I was making, is that this is public information that the US Army is using it in a tactical environment. So, you know, that would be in a tent, for instance, you know, for warfighters, potentially, in a tent that they would just hang up an access point, a LiFi access point, and have connectivity within that tactical Operation Centre. So yeah, that is indoors, technically, because it's in a tent.”

Bill Galione: “That's the exit point, right? So, you know what we provide our access points. And what we call stations or dongles, the dongle would plug into the GETAC PC or a tablet and the access point is sort of just like an access point that you have in your house for LiFi. In this case, using visible light doesn't have to be visible light. As Alistair said IR is also an option but uses visible light spectrum downlink, and IR uplink currently.”

Host: “How does an organisation start or start thinking about deploying LiFi technology within your organisation?”

Alistair Banham: “So, we've got within pureLiFi, we've got a kind of a fanatical focus on keeping things simple. You know, we want to keep it very simple. LiFi is a simple technology to pull it and deploy. And we have to keep it simple because guess what, you know, LiFi is ubiquitous. Technology has a ubiquitous presence. Everybody's familiar with LiFi, everybody uses it and likes it. But it doesn't do everything, as we keep saying. So, we have to keep the experience. Very, very simple.”

Host: “Can LiFi work in unison with, for example, a traditional WiFi connection, can I use both simultaneously? Do they peacefully coexist?”

Bill Galione: “They coexist, and you're not going to have a coexistence problem or interference problem between the two because it's a very different, very different spectrum, light spectrum RF spectrum.”

Host: “In regard to, you know, connectivity, is there anything that could possibly interfere with a LiFi connection, say Sunlight?”

Alistair Banham: “We've done a lot of testing and sunlight is not a problem. So, now there are ways to mitigate that with multiple access points, and, you know, maybe a wider field of view, there are knobs that we can play with to mitigate that issue. But yeah, you know, if you block the light, you'll temporarily lose signal.”

Host: “So, in regard to security, again, what objections do you typically encounter from an IT manager? And have you been able to successfully overcome those I'm sure that the IT managers are very concerned about anything being transmitted on their network.”

Alistair Banham: “In terms of security, I mean, again, back to the journey, we're on starting out with The Defence and the Government, these guys try to break things, they try to prove that it's not secure, it's not reliable. You know, it's a very good way to begin your business and rent things out the defence does a good job of that. So, we have not gotten pushback that I'm aware of on any security aspect, these systems go through a very rigorous accreditation process within the defence community. So, that gives us tremendous credibility, with non-defence customers as well.”

PEGGY SMEDLEY SHOW Episode 793 - Harald Haas on LiFi Technology

A few weeks ago, professor Harald Haas was once again invited as a guest speaker on the Peggy Smedley Show. The Peggy Smedley Show is an authoritative conversation hosted by tech journalist and sustainability influencer, Peggy Smedley with market leaders, authors, consultants, analysts, and more.

Peggy Smedley and professor Harald Haas talked all about what LiFi is and why it is important. He says it is wireless communications like we have with WiFi and with cellular, but we don’t use the radio spectrum, we use the ordinary light bulb in your home for high-speed data connection.

They also discuss the following topics:

• The spectrum crunch and why we need enormous amounts of data.

• Vulnerabilities with radio communication.

• The importance of standards and interoperability.
  

Below are some of the conversations of the podcast about LiFi technology. Some of the conversations have been edited:

Prof. Harald Haas: “And let me tell you why LiFi is important. And before I do that, let me tell you also what LiFi is.  LiFi is wireless communications like we have with WiFi and cellular. But we don't use the radio spectrum, we use your ordinary light bulb in your home for high-speed data connection. In a nutshell, it's LiFi.”

“So, there's this vulnerability in the RF domain and LiFi provides orders of magnitude better security, firstly, Layer Security in order to have not only more data but also more secure data going forward.”

“The optical spectrum will be able to deliver that because the total resources that are available are 2600 times larger than the entire radio spectrum. So, there's plenty of resources out there for building these networks and high-speed connectivity.”

Peggy: “So, when you think about when you talk about radiofrequency, and all of these things right now, what made you come up with then with LiFi is being the answer to all of these things that are frustrating us with data downloads, data speeds, you know, that's what we all talk about when we're at home?”

Prof. Harald Haas: “That's an absolutely great question. And the way I came up with that is because my background is as a wireless communications researcher. And 20 years ago, I left Siemens where I was involved in developing key technologies for 4G cellular. And there are regular conferences, the World Radio conferences, that would allocate new spectrum to cellular. And it was clear at that time that the amount of radio spectrum that would be allocated to cellular systems would not be sufficient to provide the resources for what was coming up the mobile, the mobile internet.”

“So, I saw that coming. So, I went into academia. And at the same time, I was inspired by colleagues in Japan, Professor Nakagawa at Keio University, who played with the wide high brightness LEDs for data communication. I was inspired by that and continued to start my own research, in the sense that we wanted to not develop optical wireless communications in the sense of TV remote controls where basically if an intentional connection, you control your TV with an optical data link. So, we wanted to build our networks, we wanted to build mobile networks that would allow mobility.”

“So, like in your WiFi use cases, if you have your WiFi handset, your WiFi phone, you're on Zoom, you can walk around, and you will not be disconnected. And I wanted to say I have the same experience but using light as a data bearer. And I, therefore, called it LiFi in analogy to WiFi, really signifying that we want to build networks not basically, point-to-point links. And so, I came up with the term LiFi, we build demonstrators, we built the proof of concepts. And as you said, we built a proof of concept 10 years ago that we showed at TEDGlobal that attracted a lot of interest. And we streamed a video from an off-the-shelf sort of $1 LED light bulb at a time.”

“So, with LiFi, what you really have is 2600 times more spectrum than the entire radio spectrum. It's free. It's unregulated. No country in the world regulates the light spectrum. So it's a free resource, and everybody can use it anywhere. So, that allows us to be equitable and allows us to build systems, the nervous system, essentially everywhere where we needed.”

“And the reason why many people are not connected that living in remote areas is because there is no business case to put a fibre into a remote village. So, we need to have something that allows even remote places to be connected at gigabit data rates that LiFi is capable of.” 

“So, that's why we need to build also free-space optical communications, which essentially is a fibre connection without the fibre. So, we are building a connection, laser connection beaming the internet from a tower from a mast, to a house or to another tower, and then distributing the network.”

“And what's important is, we can do that with solar cells. And we can use solar panels that we have to put on our homes in order to be more energy-autonomous given the current situation. It's even more important to realise that, but these solar panels can fulfil two functions at the same time, they can take the photons from the sun and convert them into energy. But they can also take the photons of a laser data transmitter and convert it into data.”

“So, we've demonstrated the lab sort of three-gigabit data reception with a solar panel, with a solar cell. And the important thing is, it can be affordable because the technology can be low complex, we can get rid of some hardware elements, which are very costly, such as beam acquisition and tracking, and make it very, very simple and therefore low costs, and thereby building sort of a mesh network and connecting the unconnected, and allowing them to take part of the benefits of a digital society.”

Prof. Harald Haas: “For the LiFi indoor networking, I think we clearly need a standard because it touches all consumer devices, it touches your smartphone, your smartwatch, your smart fridge, all your smart devices at home, have to be connected with LiFi and it's a simple case.”

“But the good news is that there is a standard looming and ascending on the horizon in half a year to a year within the IEEE family. So, the IEEE stands for the Institute for Electrical and Electronic Engineers in the United States.”

“And interestingly now, there will be a new standard within the same family of WiFi, which is a LiFi standard which has the reference bd.”

Peggy: “So, is this to create a common Nervous System so to speak? What does interoperability mean then if you have WiFi, you have LiFi, what does this create then for the average consumer when they want products, because sometimes just because we have interoperability doesn't necessarily mean they talk to each other?”

Prof. Harald Haas: “And the optical spectrum is out there in order to deliver these resources for growing the nervous system towards a fully integrated network that allows sensing, communication, computing control, robotics, that really our cars in the future, that are autonomous on our road, are safe, and allow level four and five self-autonomous driving and you need like a human body if your fingers won't be that sensitive, you wouldn't be able to do all the things we can do in this world. And we don't just want to make the machines similarly capable. And that doesn't go without building lots of connections, to cars, aeroplanes, drones, underwater remote-operated vehicles, and also satellites and connecting satellites and satellites to the ground. So, we are talking about a huge undertaking, but a huge opportunity here. And we see the products to basically deliver on that nervous system being created as we speak.”

Peggy: “So, the really exciting thing that the consumers need to understand because we're consumers and businesses together is that there's going to be this great opportunity to see what we could do in our personal lives and our professional lives. And see how LiFi is going to actually change our world. And what we need to understand is that LiFi is going to change our world in a different way than we can imagine right now.”

Prof. Harald Haas: “But let me also say a few things about some general misconceptions, which I hopefully have the opportunity to take head on here is LiFi, requires a line of sight link. And people say that LiFi can be blocked by just putting your hand in front of the link. That is, in a sense, true. But it is also true that we can build very sensitive detectors that would allow data reception, even in a blocked scenario, or in a room when the light comes off a wall.”

“And also, we build spatial diversity systems where you have multiple LiFi transceivers in your phone, one at the backside on the front side, and if one is blocked, you still have the other one that would receive data.”

“So, we build fairly robust systems with LiFi, it also works under strong sunlight, because we have developed and patented modulation techniques that are robust to ambient light. So, it works outdoors as well as indoors, it works underwater, unlike radio, so you can connect and remotely operated vehicles underwater.”

“So really, that directionality is a key feature, you would argue that you can build directional RF communications. That's true, but there are always in RF sight loops that go in different directions rather than the main beam. And that approach, that is a security vulnerability that LiFi doesn't have.”

“And also, should say one very important point here is on data density. We talked about data rates, and we talked about terabit per second data rates. But it is an important metric. But it's a second very important metric as well, it's data density. So, if you're at home in your living room, and you have, say 10 people that want to get access to WiFi. And let's assume your WiFi delivers one gigabit, which is a good headline number. But usually what happens is that the 10 people in that room have to share that one gigabit, so they actually get 100 megabits so it's much lower than the peak data rate.”

“And lastly, what I want to say is we are currently in our research and our LiFi research and development centre, we are currently building really terabit per second optical wireless networks that do exactly what I've just described, giving users their private beam based on a multi-beam approach and a grid of beam approach and allowing also mobility and allowing sort of blockage of light. So, these are very important all these very important facts and I was hoping to convey and thanks for giving me the opportunity here, Peggy.”

Li-Fi Conference 2022

The Li-Fi Conference 2022 Edition was a great success. Li Fi Tech News will very soon write articles on the topics treated at the Conference.

What is LiFi?

LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light-emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).

VLC uses light as a medium to deliver high-speed communication like Wi-Fi and complies with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional, and fully networked wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11.

How does LiFi work?

LiFi is a high speed, bidirectional, and fully networked wireless communication of data using light. LiFi constitutes of several light bulbs that form a wireless network.

When an electrical current goes through to a LED light bulb, a stream of light (photons) emits from the lamp. LED bulbs are semiconductor devices, which means that the brightness of the light flowing through them can change at extremely high speeds. The signal is sent by modulating the light at different rates. The signal can then be received by a detector that interprets the changes in light intensity (the signal) as data. Also when the LED is ON, you transmit a digital 1, and when it is OFF, you transmit a 0.

LiFi Benefits

The primary benefits of LiFi are as follows:

• Security: Provides entirely secure access. Where there is no light there is no data.

• Safety: Does not produce electromagnetic radiation and does not interfere with existing electronic systems.

• Localisation: Allows localisation due to the small coverage area of LiFi access point - localisation can be used for very precise asset tracking.

• Data density: Provides ubiquitous high-speed wireless access that offers substantially greater data density (data rate per unit area) than RF through high bandwidth reuse.
