LED wireless communication technology research

Some people think that electromagnetic radiation may lead to certain diseases, while others feel that living in a wireless environment is simply a chronic suicide. Now, researchers from the Boston University are working on a new technology that uses LED to develop wireless communications without radiation.

The technology uses a low-power light-emitting diode LED, the researchers hope to use visible light instead of radio waves to avoid electromagnetic radiation.

Professor Thomas Little of Boston University points out that "based on LED communication network, can use the existing wire, eliminating the trouble of wiring, and the LED lamp has the advantages of low power consumption, high reliability, no electromagnetic interference etc.. And the system can be applied to the existing lighting system, as long as the bulb is replaced by a light-emitting diode. "

LED wireless network is also the advantage of its disadvantages, when the light is not lit, of course, can not receive the signal. However, because the light can not penetrate the wall, so the security of this LED wireless network is relatively high.

At present, researchers believe that the network transmission speed can reach 10Mbps, but the subsequent product speed will be higher. Moreover, the power consumption of the LED lamp is less than that of the radio frequency technology, and at the same time, the wireless network is also deployed at the same time, which is a long-term energy saving technology without increasing the energy cost.

It is reported that the U.S. government has funded this project is called smart lighting project, and I hope the research can have other applications
