Mass Market Applications for Li-Fi

A new EU consortium of businesses and academia partners announced the three-year project “Enhance Lighting for the Internet of Things” ELIoT, aimed at developing mass market Internet of Things (IoT) solutions using Li-Fi, a next generation wireless communications network, traveling over light instead of radio waves.

The future IoT will place much higher demand and emphasis on the data rate, reliability and latency of wireless connections. If many IoT devices communicate in a confined space, the demand for radio frequencies will increase much faster than previously expected. With Li-Fi, the ELIoT consortium will explore a networked wireless communication technology operating in the previously unused light spectrum, besides Wi-Fi and cellular radio.

As such, Li-Fi has many use cases for commercial, industrial or outdoor applications. It could function well in environments where certain radiofrequencies are not possible or allowed. For outdoor usage, it could offer high-bandwidth point-to-point links from rooftops, between streetlights or to consumers’ homes for next generation networks. Higher network demands might come from software-controlled production, virtual and augmented reality and autonomous driving where Li-Fi could prove useful.

ELIoT has started in 2019 as a project funded by EUs biggest research and innovation program, Horizon 2020. This program promises more breakthroughs by taking great ideas from the lab into the market. ELIoT receives six million euros 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 University of Technology and the two Fraunhofer Institutes HHI and Fokus. Even more companies will shortly be added as associated partners.

“With ELIoT, we have established a powerful consortium of companies and organizations from the European lighting and communications industries. ELIoT forms a closed value chain with partners representing the components, chipsets, systems and applications sectors and research institutes, working together on the commercialization of Li-Fi for the future IoT,” says Volker Jungnickel of Fraunhofer HHI, who serves as project coordinator.

Prof. Jean-Paul Linnartz, co-initiator of ELIoT and also leading Signify’s research in Li-Fi, confirms the potential of ELIoT: “Li-Fi can deliver high-speed communication, interference-free with high reliability. The available spectrum can be fully reused in every room. The lighting infrastructure is in an excellent position to provide wireless connectivity for the rapidly increasing number of wireless devices in every room.” (Source: Fh. HHI)
