Recently, the Internet excited the news about running in Moscow city free Wi-Fi network . Fortunately, devices in which to work, users are more than enough. This practical book of the future , and the phone for divers, photographers , and a pocket notebook replacement . But for the Chinese like that, it seems, will soon become irrelevant. After all, scientists from that country have created a wireless network from the LEDs.
The replacement of Wi-Fi found scientists from the Institute for Research in the field of semiconductors Chinese Academy of Sciences. To send a signal they used conventional LEDs located at the Institute of ceiling fixtures.
I must say, the idea is very interesting. It turns out that neither the lamp, then the access point. In this case the Chinese recorded the speed of data transmission is connected to a lamp laptop at two megabits per second.
However, on some commercial uses technology developed by Chinese speech yet. First, it is not yet fully tested. Secondly, such a wireless network signal does not penetrate through obstacles such as walls. But after running technology, it is expected to be interested, for example, developers of "smart homes".
