ELIoT (Enhance Lighting for the Internet of Things) H2020 Presents LiFi Solutions For The Mass Market
The Fraunhofer HHI announced on their website the completion of the ELiOT project. The coordination of this project was done by the Fraunhofer Heinrich Hertz Institute (HHI). The consortium has developed LiFi solutions for the mass market since 2019, enabling wireless data transmission via light in the Internet of Things (IoT). To conclude the project, the researchers demonstrated a new LiFi infrastructure in real-world application scenarios and presented a roadmap for LiFi in the future IoT.
To make LiFi commercially viable, the ELIoT consortium has researched core aspects and new functionalities of the LiFi infrastructure. These include precise position detection (positioning), wireless networking between multiple transmitters and multiple receivers (multicast communication), and increased security standards. ELIoT has developed and implemented these features and demonstrated them in real-world application scenarios. The final EU project report firmly stated that ELIoT delivered "exceptional results with significant immediate or potential impact."
Achievements of the ELIoT project
The consortium demonstrated the use of LiFi for positioning in the industrial sector, where the focus was particularly on integrating positioning and communication in one unified system. LiFi makes localization much more accurate than was previously possible with radio technologies. Additionally, the integration of LiFi and 5G was also demonstrated in an industrial environment. Such systems combine the advantages of radio solutions, such as high mobility, with the high capacities of LiFi.
Furthermore, ELIoT has optimised the use of LiFi infrastructures in office environments, addressing the core challenges of the modern workplace. Distributed LiFi MIMO bypasses the data congestion issues of traditional networks and provides improved data protection.
In the ELIoT demo on fixed wireless access, the researchers also presented a pioneering solution for the last mile of optical network connectivity. In the outdoor area, one possible scenario in the future would be point-to-point connections with high bandwidth from roofs to small radio base stations, between street lamps or to private homes (wireless-to-the-home).
Mobile authentication is becoming increasingly important not only in industrial but also in private settings. With the help of LiFi, the ELIoT researchers demonstrated an energy-saving LiFi-enabled door lock that can be easily integrated into existing LiFi infrastructures. The lock has an integrated LiFi transceiver that enables secure key exchange with a server on the network. Using LiFi, the key's code can now also be renewed more securely than before via WLAN.
Finally, ELIoT has been able to significantly reduce the load on wireless networks in the context of digital signage in shopping malls by using LiFi to transmit video to displays in real time.
ELIOT also improved the manageability of LiFi modules, i.e. their installation and maintenance. LiFi networks use a central module to transport the data signals to several distributed LiFi modules. The researchers in the ELIoT project discovered a more robust and manageable solution for data transport: Plastic Optical Fibers (POF). Different LiFi modules are accessed with different colors of light, which transmit the data simultaneously over the same fiber. This means that one thin plastic fiber can replace a whole bundle of cables, reducing installation costs.
In addition, the researchers successfully provided an open reference architecture to support the IoT using the existing lighting infrastructure. The architecture is very flexible and can cover a wide variety of applications, which together cover the future mass market. The consortium reached a consensus on the optimal architecture. The milestones in the project contributed significantly to the standardization of lighting and telecommunication infrastructures in ITU-T G.9991, IEEE P 802.15.13 and P802.11bb, and they form the basis of the roadmap for the deployment of LiFi in IoT.
Partners in this EU project were Signify (formerly Philips Lighting), Nokia, MaxLinear, Deutsche Telekom, KPN, Weidmüller, LightBee, as well as Oxford University, Eindhoven University of Technology and Fraunhofer Institutes HHI and FOKUS.

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.
Fraunhofer HHI
The Fraunhofer , Heinrich Hertz Institute, HHI, also known as Fraunhofer HHI or Fraunhofer Heinrich Hertz Institute, is an organisation of the Fraunhofer Society based in Berlin. The institute engages in applied research and development in the fields of physics, electrical engineering and computer sciences.
The Fraunhofer Heinrich Hertz Institute develops mobile and stationary broadband communication networks and multimedia systems. Focal points of independent and contract research conducted by Fraunhofer HHI are photonic components and systems, fiber optic sensor systems, and image signal processing and transmission. Future applications for broadband networks are developed as well. Research in this area focuses on 3D displays, UHD panorama video production, human-machine interaction through gesture control, optical satellite communication and data transmission technologies such as visible light communications.
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.
