Li-fi is a technique that uses LED light to transmit data. use of RGB Leds drastically increases the bandwidth which is already quite large.,..

It also solves the problem of nearby wi-fi zones interfering and limiting bandwidth and you can protect your li-fi network by simply closing the curtains :p
person a) what your wi-fi routers name?
person b) i use li-fi not wi-fi *point at the led sealing lamp*
