This week representatives of the company Philips announced the beginning of the practical testing data transmission technology “Li-Fi”. Ground for running selected a typical office area with high load on network devices is the residence of the Icade, a French investment company in real estate. Besides General convenience, the developers want to test the reliability of the news and the security of data transmission.
The principle of Li-Fi is based on the fact that the signal is not transmitted by radio waves, and using photons of light in the infrared frequencies. Otherwise it’s the same broadband access point to the Internet is the transmitter, connected to the main cable, and USB receivers for your custom gadgets. You could just integrate the Board into the device, but the developers purposely left a large space for the users.
The advantages of Li-Fi include the absence of interference, the link can work side by side with sensitive equipment. The light does not penetrate through walls even made of plywood, no data loss, but if you combine the chain of transmitters, the signal can be fed into the deep bunker without the use of cables. And there is no problem with the quality of reception of the light either comes on the receiver or not.
Cons are also obvious, the transmitter and receiver must be continuously in the zone of direct visibility. And the people in the office have a habit of walking back and forth, to move objects in the workplace to get a laptop in a cozy corner, where no one gets signal. In short, the experiment is the experiment. But as a bonus – speed access to the Internet via Li-Fi from Philips reaches 30 MB/sec.
