The use of infrared to communicate has a long history, IRDA has built communication protocols for PDAs, printers and laptops for many years," said Boston University professor Thomas Little. "What we are doing now is to seize this opportunity. Embed networking features into the LED lighting revolution. With the replacement of incandescent and fluorescent lamps, we hope to embed networking technology into LED lighting. â€
Currently, LED-based communication functions using infrared LEDs, such as remote control functions, will be suitable for the use of visible light, so that transceivers in digital devices can communicate with the lighting device. These lighting devices will be connected to the Internet via wired devices. Unlike RF-based WiFi access points that must share spectrum among all users, line-of-sight communication via visible light may enable different data streams to be fed into each device.
