Oppo Mobile Telecommunications filed a design patent for a smartphone with Li-Fi components

Oppo

Guangdong Oppo Mobile Telecommunications Corp., Ltd, stylized as oppo, is a Chinese consumer electronics and mobile communications company headquartered in Dongguan, Guangdong. It is a subsidiary of BBK Electronics Corporation along with OnePlus, Vivo, and Realme. Its major product lines include smartphones, audio devices, Blu-ray players, and other electronic products. In December 2019, a design patent was filed by Guangdong Oppo Mobile Telecommunications with the CNIPA (China National Intellectual Property Office). The patent was published on July 31, 2020, and includes 24 product images, combined with a short description showing that this smartphone is suitable for Li-Fi communication.

It is a modern smartphone with narrow screen edges and full-screen design. No front camera is visible. The images show that this Oppo phone will be equipped with a pop-up camera, as we know from the Oppo Reno series.

A rectangle can be seen on the pop-up system, which is used for LiFi communication. This also applies to the rear, right next to the centrally placed vertical camera system, a square Li-Fi device can be seen, which works as a receiver. The photodetector converts the changes in amplitude into an electrical signal to enable Li-Fi communication with the smartphone.

The patent images also show a dual camera, however, it is quite possible that Oppo will eventually choose three, or even four cameras - as we often see with the Oppo 2020 smartphone models. The small circle under the camera system is striking. This characteristic circle is also called the O-Dot by Oppo and is only used within the Reno telephone series.

The small protruding O-Dot ensures that the phone does not only rest on the camera system when you put the device flat on the table. We can deduce from the O-Dot, combined with the pop-up camera system, that Oppo wants to place this smartphone within the relatively new and extremely innovative Reno series.

There is also a microphone on both the top and bottom of the device as well as a speaker, a SIM card slot, and a USB-C connection at the bottom. The power button can be found on the right and the button on the left logically provides access to the volume settings.

The Oppo Li-Fi Patent

A design patent is only intended to record the design, so little is stated about how Oppo intends to apply the Li-Fi technology. However, the investigative journalists at LetsGoDigital have dug deeper for additional information, and during their search found out that three days after filing this design patent, Oppo also filed an associated utility patent in China.

In the patent called 'Li-Fi device and projection system with the same', it is extensively discussed how Oppo intends to apply LiFi in mobile devices. The patented Li-Fi device can be installed in a smartphone and consists of a housing, a printed circuit board, and a Li-Fi module for signal reception.

Li-Fi not only provides a significantly higher transmission speed than WiFi but the technology is also characterised by a lower latency (delay) just like 5G, it is also possible to transfer high-resolution images with a high frame rate, for example, large video and audio files) - as stated in the patent description.

What is Li-Fi?

Li-Fi, 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 Li-Fi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC). Below is a video demonstration of Li-Fi technology by professor Harald Haas:

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 Li-Fi work?

Li-Fi is a high speed, bidirectional, and fully networked wireless communication of data using light. Li-Fi 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 which 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.

Nav Wireless Technology Ltd

Nav Wireless Technology, an R&D initiative in wireless technologies, is currently developing a Li-Fi (Light Fidelity) technology-based communication facility at SMIMER (Surat Municipal Institute of Medical Education & Research). The company has extended its expertise to provide faster and safer light-based communication for COVID-19 patients and all the medical professionals.

In regards to COVID 19 cases, SMIMER developed isolation wards in a very short amount of time. Nav Wireless Technology stated:

“We are the only company in Asia in the Li-Fi sector to receive the first commercial Li-Fi project for the healthcare sector. We will set up around 600 such units there which are completely MADE IN INDIA. All the formalities related to this initiative have been completed with respective authority and we will start the commencement of the installation process very shortly", said Hardik Soni, co-founder & CTO, Nav Wireless Technology.

Constant monitoring of the patient's health condition in the hospital is either manual or wireless fidelity (Wi-Fi)-based system in the ICU. The Wi-Fi-based system becomes slow in speed due to exponentially increased scalability. In this scenario, Li-Fi finds the places wherever Wi-Fi is applicable with additional features of a high-speed data network. Apart from the speed factor, Li-Fi is a more suitable in-hospital application for monitoring the patient's conditions without frequency interference with the human body.

"We saw the live demonstration for monitoring the patient’s conditions such as SPO2, ECG, HR, NIBP using respective sensors integrated with these Li-Fi Transceivers. The data was processed with LiFi transceivers and sent to display unit in the form of graphs, charts, or in required formats that is helpful for the medical teams during the treatment of COVID-19 cases”, said Dr. V S Srivastav, Professor, and Head, Department of Medicine, SMIMER.

With this, all the patients and medical staff for more than 1,000 beds isolation wards will be able to use a radiation-free communication network, connected to hospital instruments such as ventilators data, etc. Furthermore, they will access the internet with a lighting speed compared to existing Wi-Fi internet.

"The Transceiver's network in the hospital for monitoring the patient's conditions such as temperature, pressure, heartbeat, glucose level, and respiratory conditions using respective sensors integrated with our LiFi Transceivers. NavTech LiFi Transceiver developed to increase data security, high capacity, and high speed, eco friendly, and with patient safety," said Soni.

Li-Fi is a mobile wireless technology that uses light rather than radio frequencies to transmit data. In India, Nav Wireless is the only player working on Li-Fi in this segment. The company has successfully installed such a Li-Fi technology-based communication facility for various government institutions and private premises. With LiFi technology-based solutions, Doctors and Hospital Staff are minimized to the risk of spreading coronavirus disease and at the same time provide a live health data monitoring system.

CEA-Leti announces a throughput world record 5.1 to 7.7 Gbps in (VLC) using a single GaN blue micro- light-emitting diode (LED)

CEA-Leti announces a throughput world record 5.1 to 7.7 Gbps in VLC using a single GaN blue micro- light-emitting diode (LED)

CEA-Leti Announcement

A few weeks ago, CEA-Leti, a Grenoble, France-based research institute for electronics and information technologies and one of the world's largest organizations for applied research in microelectronics and nanotechnology, made the announcement of the throughput world record of 5.1 Gbps in visible light communications (VLC) using a single GaN blue micro- light-emitting diode (LED).

Their data transmission rate of 7.7 Gbps achieved with a 10 µm microLED marks another step toward commercialisation and widespread use of LiFi communication.

Benoit Miscopein, a CEA-Leti research scientist, stated that Li Fi technology has exciting potential for mass-market applications. He further stated: "Multi-LED systems could replace WiFi, but wide-scale adoption will require a standardization process to ensure the systems' interoperability between different manufacturers. The Light Communications Alliance was created in 2019 to encourage the industry to implement this standardization.

CEA-Leti MicroLED Li Fi system

CEA-Leti said that: “In addition to a stand-alone WiFi-like standard, the possibility to include this new technology as a component carrier in the downlink of 5G-NR, a radio-access technology for 5G mobile considerations, is also under investigation to bring a large additional license-free bandwidth. This may be feasible because CEA-Leti's LiFi physical layer relies on the same concepts as WiFi and 5G technologies," said Miscopein. "Matrices of thousands of microLEDs could also open the way to mid- to long-range applications, such as indoor wireless multiple access.”

To preserve the bandwidth of each microLED within a matrix, it requires that each signal is generated as close as possible to the micro-optical source. CEA-Leti said: o meet this challenge, we expect to hybridise the microLED matrix onto another matrix of CMOS drivers: one simple CMOS driver will pilot one microLED," Miscopein said. "This will also enable the additional feature of piloting each microLED pixel independently, and that allows new types of digital-to-optical waveforms that could eliminate the need for digital-to-analog converters commonly used in the conventional 'analogue' implementations of LiFi.

OWNII Coin (Li Fi Cryptocurrency) - Launch Update

OWNII Coin (Li Fi Cryptocurrency) - Launch Update

A while back, we wrote an article about a Li-Fi cryptocurrency called “OWNII Coin”. Global Greenology, a privately owned global manufacturing and design company specialising in environmentally friendly, energy-efficient building solutions, developed a cryptocurrency for Li-Fi implementation.

What are cryptocurrencies?

Cryptocurrencies are virtual or digital currencies that have no centralised regulating authority. This means that money is produced and transferred without the intermediation of banks. Cryptography is used as a means of ensuring transaction security.

Bitcoin, created in 2009, was the first decentralised cryptocurrency and remains the most expensive virtual currency worldwide. Other popular cryptocurrencies include: Bitcoin Cash, Ethereum, Dash, Mixin, Litecoin, Zcash, Bitcoin SV and Monero. The cryptocurrency used in the most transactions daily was Ethereum in 2019.

The decentralised control of each cryptocurrency works through Blockchain, a public transaction database that functions as a distributed ledger. The size of Bitcoin Blockchain grows from year to year and it mounted to around 242 gigabytes as of the third quarter of 2019.

The prices of cryptocurrencies are quite unstable and strongly dependent on the market sentiment. The price of Bitcoin, for example, experienced an increase from about 371 U.S. dollars in January 2016 to a peak of over 13 thousand by December 2017. Also, market capitalisation of Bitcoin experienced a rapid growth in that time period.

What is 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 Li-Fi in the United States and developing nations abroad and is sold privately. The pureLiFi company has manufactures and distributes the equipment needed to stream communication through existing LED bulbs but to implement Li-Fi , installation of this equipment is necessary.

Global Greenology, creator of OWNII Coin, states that the OWNII Coin will promote the creation of a new internet infrastructure in the United States and worldwide. It will also create numerous opportunities for employment, business ownership, and entrepreneurial endeavours selling equipment and services. The multiple streams of revenue that OWNII Coin represents brings unprecedented value. Once launched, the infrastructure creates new technology, software, products and services making this coin and ecosystem very valuable.

OWNII coin and the resulting financial capital it generates allows Global Greenology the opportunity to build the OWNII Ecosystem and effectively provide the technology to reach the end user and provide opportunities for manufacturing of the Li-Fi light bulbs and connection devices. It opens a level playing field for the smaller business owner or an entrepreneurial start-up company to get involved on the ground floor of this opportunity.

OWNII creates wireless communication, that is faster, addresses issues with internet security, allows localisation due to small coverage area of Li-Fi 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.

Finally, the OWNII Coin system exploits the advantages of cryptocurrencies over fiat currencies as a medium of exchange. In particular, it does not require any single agent or institution be trusted to keep an honest ledger, provide low transactions costs, or offer increased security to customers. The technical elements and infrastructure needed to implement the OWNII Coin system is already established and ready for execution, the only real challenge is the dissemination. Global Greenology’s establishment of the OWNII Coin system has the potential to disrupt our current expensive wireless communication system.

The primary benefits of Li Fi 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 small coverage area of Li-Fi 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.

Launch Update

Due to the current Corona virus pandemic, the public launch is being delayed. However, Global Greenology is currently planning the launch of OWNII Coin in 2 phases. The first phase being a private sell of the token in which you can pledge to purchase your amount but will not have to pay for it until the market stabilised. The second phase will be a public purchase just before going live on the exchange. A website specifically for the OWNII coin is also being developed by Global Greenology. Li Fi Tech News will keep you updated on the progress of the OWNII Coin.

Exploring the Impossibility of Decentralization

Exploring the Impossibility of Decentralization

Grade school might tell you anything is possible. Complete and total decentralization, however, is not– at least sustainable. 

The premise that decentralization is impossible hinges on the fact that decentralization “experiments” such as Bitcoin have approached towards degrees of centralization.

For example, Bitcoin’s Proof-of-Work (PoW) mechanism relies on many different nodes to “mine,” or verify and facilitate transactions. These miners are rewarded a portion of transaction fees and a shot at winning the Bitcoin block reward, which is currently 12.5 bitcoins or about $115,000– a not insignificant prize dished out about 144 times per day. 

This has incentived the creation of “mining pools,” or a collection of nodes that work together and divide the prize among the operators. Mining pools have taken what would otherwise be a decentralized utopia and coalesced a degree of centralization. The current state of Bitcoin mining is far from a single entity controlling the network with a  51% lion’s share, but it still highlights the downfalls of decentralization. 

There are cryptocurrencies that utilize different consensus mechanisms such as Proof-of-Stake and Delegated-Proof-of-Stake, and they manage to address some of Bitcoin’s drawbacks (such as high energy costs to mine), but they still leave the glaring decentralization issue. 

A particularly noteworthy concept is that Bitcoin, a network with no single individual party dictating its future, has gravitated towards centralization on its own. Centralized entities may receive some flak in the cryptocurrency and blockchain community, but they are at least able to enforce and control certain elements, a task nearly impossible for a theoretical, fully decentralized entity. 

Do we really need full decentralization?

The core tenet of decentralization, at least among the common blockchain ethos, is that decentralization insulates the network from tyranny and corruption, a duo that has plagued human governance and economics since the dawn of organized civilization. 

The same concepts that power Adam Smith’s “free market” philosophy that underpins modern economics encourage decentralization as long as every party is properly incentivized (mining rewards) and has access to somewhat similar resources (electricity, reasonable utility costs, etc) as the next. 

The glory of today’s blockchains isn’t so much derived from the idea of an Utopian decentralization, but more so as a rebellion against the status quo of centralized banks dictating the economy, individuals being tethered to the success of their government, and the ability for large tech corporations and banks to shut down financial accounts at will. 

There are several degrees of “decentralization”, and even though not “perfect,” even smaller decentralization improvements can be disruptive to the existing “centralized” status quo. 

The goal is to figure out which areas will be impacted first; and which are the top use cases given the infrastructure’s properties (security, decentralization, scalability). 

For example, think of the idea of a decentralized “Uber,” a popular thought experiment in the blockchain entrepreneurial community. When someone needs a car to pick them up, what would they prefer: a nearly immediate connection to a driver courtesy of an efficient centralized server, or waiting for minutes and potentially hours for the transaction to be verified and processed? 

Final Thoughts

Although the push towards absolute decentralization is unfeasible, and in reality, decentralization benefits vary across use cases. Simply put, we don’t need decentralization for everything– centralization tends to work just fine for most things, and it shouldn’t be viewed as an enemy of what the blockchain movement seeks to accomplish. 

Ultimately, blockchain is simply just another technology to be leveraged to solve certain problems. 

Once upon a time, centralization was the solution to the disorganized chaos of the unpredictable. Our ancestors who lived in groups tended to live longer and better lives than individuals not in groups. 

These groups evolved into tribes that utilizes some form of centralization (leadership, hierarchy, enforced order) that protected its members and utilized resources more efficiently. Eventually, tribes expanded and, however indirectly, ended up becoming countries that function using the same centralized mechanics. 

Decentralization uses the evolution of the Internet and technological infrastructure to create systems that don’t require a centralized entity’s direct oversight. However, decentralized entities can only function within the scope of a centralized society.

Today’s projects are able to enjoy both the benefits of existing within the confines of a centralized society and the possibilities enabled by blockchain and the Internet. While full decentralization might be impossible, there’s no reason to fuss.

pureliFi successfully raises $18 million to supply Li-Fi components for the mobile device market

pureliFi successfully raises $18 million to supply Li-Fi components for the mobile device market

Photo credit to pureLiFi

pureLiFi just announced successful fundraising of $18 million (£14 million). The funding round includes Temasek, an investment company headquartered in Singapore, and the Scottish Investment Bank. The investment will permit the company to further develop miniaturised LiFi components and make them available in mobile devices. pureLiFi develops technology for communication networks that integrates data and lighting utility infrastructures. It offers a LiFi enabled a device that converts the beam of lights into an electrical signal. The signal is then converted back into data. The company was founded in 2012 and is headquartered in Edinburgh.

pureLiFi has been building partnerships with a range of companies to bring Li-Fi devices at a consumer level.

pureLiFi CEO Alistair Banham. said: “Device manufacturers are looking for new ways to provide devices with faster, more reliable and secure connectivity. LiFi is the natural next step in the evolution of global wireless communications and pureLiFi is leading the way to provide this technology to the market.”

“Our investors believe in our team and our strategy to provide LiFi for every light and every device, and we have the products to support mobile device integration of LiFi.”

Li-Fi is a Visible Light Communications (VLC) system. Like Wi-Fi, it’s bidirectional wireless communication technology. But, where Wi-Fi uses radio waves to transmit data, Li-Fi uses visible light from LED lightbulbs fitted with a special chip.

In simple words, Li-Fi is the internet through Light. You can watch the video below to see how Li-Fi works:

Professor Harald Haas, co-founder and CSO of pureLiFi said: “After more than a decade of persistent and systematic development of key technologies for wireless communications using light and the demonstration of the almost unlimited capabilities of LiFi for secure gigabit wireless connectivity for many use cases such as machine-to-machine communication, we are now at the precipice of a watershed moment for LiFi. I am absolutely delighted that we are now empowered to get the LiFi mass-market avalanche in motion!”.
