Lighting positioning new LED Communications Technology Expo debut

The application of new technology will LED lighting has become more intelligent and humane. In the days before the end of the fifteenth China International Optoelectronics Expo, LED light communication technology made its debut in Shenzhen.

It is understood that the "white light communication technology is an emerging technology communication currently competing research and development in developed countries, the technology principle is to compile will need to transmit information into a modulated signal, attached to the drive current of LED lamp with pulse width modulation light source, using indoor everywhere as transmitting vector. Through the professional terminal or any intelligent terminal to receive and decode, thus completing the information transmission through lighting purpose.

The new communication technology uses the LED module to load the transmitter module, which is not easy to be disturbed by the object and the weather, the positioning accuracy can reach 1 meters, and it is more than 10 times higher than the wireless indoor positioning technology.

According to R & D side said that this technology will be the first to promote the future in Shenzhen. Compared with the traditional technology, this new technology is the first in the country, five times increase in positioning accuracy, but the cost can be reduced by 80%, both have a great advantage in the communication positioning or cost control.
