The company Philips announced that it began testing its technology Li-Fi (Lighting Fidelity) at the offices of the French investment company Icade. At the moment, Li-Fi provides employees with broadband access to the Internet using led’s that transmit information at speeds up to 30 Mbps using light waves.
In the offices of the company Li-Fi works via a special USB dongles, with embedded modems. To use the network of Li-Fi, the user must connect the device to your computer. To access the network dongle uses infrared communication, which is much safer and more reliable Wi-Fi. Communication via visible light works by switching the supply voltage to the LEDs at very high frequency, invisible to the human eye.
From Li-Fi has a number of advantages. For example, the network can operate in conditions where the use of Wi-Fi could interfere with the proper operation of the equipment. As for data transmission Li-Fi uses light from the diodes, the technology can be successfully used under water.
However, despite all the prospects, the difficulties with the widespread introduction of Li-Fi could also be because it has drawbacks. For example, through the wall network signal is not transmitted, this means that to transmit the information necessary line of sight that already complicates equipment Li-Fi-network of a large building, which houses many separate rooms. However, technology definitely has the right to life. Would be very interesting to observe how it will develop in the future.
