Light Fidelity or LiFi is a revolutionary high speed, bi-directional, fully networked wireless communication technology similar to WiFi. It is touted to be the ‘next big thing’ in the field of Internet technology. Unlike WiFi (Wireless Fidelity), that operates on a radio frequency (RF) of upto 5 GHz, LiFi can transmit about 10,000 times the data available on RF spectrum.
LiFi is estimated to be more than 100 times faster than existing WiFi systems and will usher in an era where machines will literally fulfill all our needs. LiFi can be used in denser medium like sea water.
It can be accessed in places where WiFi is normally un-operational like airplanes, submarines and hospitals. The following infographic from cabotsolutions.com. outlines the distinction between WiFi and LiFi.
