Researchers Create A New Twist On Li-fi Network Bulbs

Researchers at the University of Virginia have taken the innovation know as “Li-Fi”, in which light is used to produce a wireless network, and enhanced it with a new algorithm. The development would enable a wireless network to be established between devices that are fitted with LEDs. In other words, any two appliances or systems that have LEDs lights would be able communicate with one another like two computers on a single network.  This feature could be useful in a range of tech and household applications, but it could also make it possible to transmit more data using less energy.

“Streaming data at around 300 Mbps from each light, any and all LED lights in the vicinity could be used as wireless access points without the limiting bandwidth problems of radio frequency (RF) wireless networks. ‘We developed a modulation algorithm that increases the throughput of data in [visible light communications],’ says [Prof. Maite] Brandt-Pearce. ‘We can transmit more data without using any additional energy. As more light fixtures get replaced with LED lights, you can have different access points to the same network.’”

There are already numerous projections for potential applications of this technology. Hospitals and airplane cabins are an obvious choice, since Li-Fi doesn’t create the same interferences as RF Wi-Fi, but there’s also greater potential for creating networks in public spaces indoors and outdoors.  It could even help advance Vehicle-to-Infrastructure and Vehicle-to-Vehicle projects.
