A WELCOME UPDATE ONLi-Fi


I came across this interesting update about Li-Fi development in the LEDs Magazine written by Mark Harper reporting progress on the Li-Fi front. My article below is built on excerpts from this article. It’s really been quite a while since we’ve heard much about Li- Fi, one of those lighting technologies, like OLEDs, that is taking its sweet old time getting to the marketplace.

With the paucity of news in this area, we welcome news form Signify that it has partnered with EDZCOM, a Finnish 4G and 5Gnetworking company that will use Signify’s LED-based Truli system as part of its wireless connectivity schemes in industrial settings. A quick refresher: Li-Fi uses light spectrum rather than the radio frequencies of Wi-Fi to transmit data and the Internet. Transmission can be either via visible light or via infrared. LiFi is a Visible Light Communications system transmitting wireless internet communications at very high speeds. The technology makes an LED light bulb emit pulses of light that are undetectable to the human eye and within those emitted pulses, data can travel to and from receivers. Compared to WiFi, Li-Fi can offer advantages of wider bandwidth, in areas otherwise susceptible to electromagnetic interference (e.g. aircraft cabins, hospitals, military), and higher transmission speeds.” It is believed that Li-Fi will help offload crowded Wi-Fi systems, and offer other advantages, such as greater security. Although Li- Fi systems can serve the dual purpose of illumination, they can also exist solely as a communications conduit.

Perhaps more than any other facet of lighting, Li-Fi symbolizes the lighting industry’s intentions to morph into a provider of information technology as well as continuing with more conventional illumination. The idea at EDZCOM is to add Li-Fi to a technology mix that already includes LTE (Long Term Evolution, a telecoms standard), Wi-Fi, and other well-known components of wireless broadband connectivity. Pre-dating Li-Fi, EDZCOM lists projects with airport operators, ports, and port handlers including Finland’s Finavia, Port Oulu, Steveco, and Kalmar. The Espoo-based company also works in the mining, manufacturing, and energy industries, which would all seem to be candidates for Li-Fi. “Combining Truli and EDZCOM’s strengths and capabilities will benefit industries that heavily rely on the cluttered radio spectrum for data communications,” said Signify chief innovation officer Olivia Qiu. “Truli can help to offload conventional radio technologies and offers reliable, secure, and high-speed network connectivity where it’s needed.” Li-Fi emerged commercially around 2012, and the road to mainstream use has yet to reach its destination. Among the reasons is that gadget makers have yet to embed Li-Fi receivers in laptops and phones, so users have to attach dongles to their devices. And in a related matter, a standards battle has yet to settle down. The transportation sector is also on the radar of vendors of another long- evolving lighting technology — OLEDs — which is unrelated to Li-Fi except in the general business sense that both have been a long time coming. Recently we have about OLED possibilities in automobile tail- lights and even in recreational vehicles.
