LED white light communication technology first entered Zhuhai

On December 23, Zhuhai Huace Group Co., Ltd. and the State Key Laboratory of Semiconductor Co-Innovation held a cooperation signing ceremony for the LE D white light communication project at the Changzhou Base in Jiangsu Province. The Huace Group officially contracted to transfer the patented technology of the national LED white light communication.

LED white light communication technology is referred to as visible light technology. It is a new communication technology developed and developed by developed countries in the world. The principle is to compile information that needs to be transmitted into a special signal, and this signal is added to the driving current of the LED lamp by a pulse width modulation method, so that the LED lamp blinks at an extremely high frequency. It can also be used as a positioning reference point for every fixture in a wide indoor division, namely the "satellite" in the GPS system, to achieve accurate indoor positioning. Its precision can reach more than 10 times that of traditional technology.
