Demonstration of LightBee’s LiFi Door Lock System With An Integrated LiFi transceiver by ELIoT H2020 Project
In their research video presentations series, ELIoT H2020 project released another demonstration video of optical wireless communication with LiFi in different environments. The video showed the application of LiFi integrated in a door lock system.
In the video, Gloria Eisman, CEO of Lightbee demonstrated the LIGHTKEY, their Smart LiFi lock system.

LIGHTKEY is a wireless access control/validation solution that enables optical wireless data transmission between mobile LED light modulation and a cloud-connected optical receiver.
It offers an optimal SAFETY-COST IMPLEMENTATION balance since the LEDs are included in the mobile device and the DATA is within the optical link.
It is prepared for FIRE REGULATION and allows opening from the inside even if the lock has the key lock on ensuring exit in any situation and is returned to the locked state with keys simply with the movement of the hand.

You can watch the video below about the LiFi Door Lock demonstration:
ELIoT demonstrates optical wireless communication (Light Fidelity - #LiFi) in different scenarios. In this video a door lock utilizing the LiFi technology is shown. The door lock has an integrated LiFi transceiver to allow a secure key exchange with a server in the network.
LightBee
According to their site, LightBee is a company with an experienced team in Visible Light Communication Technology (VLC), having brought the best researchers of LED and photonic technology together over the years, in order to improve and develop VLC technology apps. Their team is multidisciplinary and has an excellent reputation in the LED sector. As one of the leading companies in this area, they have extensive in wireless optic communication, coding schemes, VLC and RF apps, sensor networks and business management.
Their team are pioneers, who inspired by VLC, offer their customers global solutions. The founders of the company have over 20 years of experience and they stand out for their vision of international B2B relationships and product strategies, having developed many relationships over all these years of dedication to LightBee. They have proved their worth through their developments in R+D (research and development) technology, having actively taken part in industrial development projects as well as R+D on an international level, which has allowed us to greatly expand our knowledge, thereby increasing LightBee’s innovative growth. Their experience is based on a combination of technical and business knowledge, with a long history of enabling companies to grow through the innovation of products and processes.
Nowadays, there is a growing number of scenarios -in-house domestic applications, traffic lights, hospitals, hotels, etc.- where illumination devices based on visible LED lamps are used. This interest is not only motivated by economic reasons (as the price of individual lamps is still higher than that of traditional ones, although it is rapidly becoming cheaper and cheaper) but by energetic or environmental considerations. These lamps combine very low power consumption with an extremely long operational life, maintaining during all their operation the same chromaticity without significant changes. LED lamps can be also used as communications emitters without losing their main functionality as illumination sources. This technique (known as Visible Light Communications or VLC) does not only maintain the usual capabilities of wireless optical transceivers (robustness against EM interference, absence of EM compatibility constraints and secure transmissions as radiation is confined by walls) but is also eye-safe (as it uses visible wavelengths). Additionally, as they are used as lamps, the amount of optical emitted power is enough to provide full transmission coverage over a regular size room. So, they have a huge amount of low-cost COTS (commercial off-the-shelf) optical emitters available that can be used wherever we need to provide illumination and to broadcast data jointly.
ELIoT H2020 Project
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.

LiFi Systems Reviews by LiFi Tech News
OLEDCOMM LIFIMAX KIT REVIEW - ONE YEAR IN
We reviewed the LiFiMax kit produced by the leading French LiFi company Oledcomm. We bought this LiFi kit system at the end of 2020. After over a year of use, we decided to write a review of this LiFi system. We looked briefly at the profile of Oledcomm, a brief history of the LiFiMax system, the Kit box contents, some testing and performance results of this LiFi system, the customer experience and our own verdict (the good and the bad points) of the LiFiMax kit.

SIGNIFY TRULIFI 6002.1 STARTER KIT SYSTEM REVIEW
We also reviewed the Trulifi 6002.1 starter kit produced by Signify, the world leader in lighting for professionals, consumers and lighting for the Internet of Things. We got this LiFi kit system with the help of PCDSI and Signify around August 2021. In a similar fashion done with our previous review of the LiFiMax kit a few months ago, we will look briefly at the profile of Signify, a brief history of the Trulifi 6002.1 kit, the Kit box contents, some testing and performance results of this LiFi system, the customer experience and our own verdict (the good points and the bad points) of the Trulifi 6002.1 kit.
