The term Li-Fi
is increasingly being used to refer to the use of Visible Light Communication (VLC) technology in wireless computer networking. (Note: This is different from "LiFi" projection TV technology introducted by Panasonic in 2007.) Li-Fi made news last year as researchers demonstrated VLC running at rates up to 800 Mbps
. Research and development work on VLC continues, with no real products expected to arrive on the market anytime soon, yet the technology intrigues those looking for alternatives to Wi-Fi
A unique aspect of VLC is that connections only work when the device has a direct line of sight to the light transmitter. In some cases, especially when using mobile devices, this could become a major annoyance. Others, though, see it as a helpful security feature: Neighbors (or even people in the next room) will have a hard time sniffing your VLC connection.
