This light bulb could work as your next wireless router.
At the University of Virginia, researchers have unveiled a new way to transmit wireless data in light waves from LED lights — a much more reliable and faster alternative to radio wave Wi-Fi.
“We developed a modulation algorithm that increases the throughput of data in [visible light communications],” Maite Brandt-Pearce, an engineering professor at the University of Virginia, told Phys.org. “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.”
Brandt-Pearce and with her former student Mohammad Noshad, who is now a postdoctoral fellow at Harvard, developed this new way to connect to the Internet.
