LiFi is a innovative way to set up wireless communication
links by means of the Led lighting networks. The LiFi protocols are distinct by
the international standard IEEE 802.15 established since 2011 by the IEEE
comity. This is the similar comity that has defined before the Ethernet 802.3
and WiFi 802.11 standard. For several specialists, LiFi is a major burst
through technology for the mobile Internet society and for the associated
objects field.
Leds are dissimilar from the other kind of lamps as they are
semiconductors. This feature gives them the ability to switch-on and off within
only some nanoseconds or billionth of a second. Transformed in terms of data
rates, this correspond to 1 Gbits/s. In order to judge against, at best WiFi
can reach 100 Mbits/s data tariff and so 10 times lesser.
