Li-Fi is a wireless communication technology that uses visible light communication to transmit data. It can provide bidirectional, high-speed wireless communication similar to Wi-Fi but uses light rather than radio waves. Li-Fi is a subset of optical wireless communications and can complement existing RF technologies like Wi-Fi and cellular networks. It allows for underwater communications, vehicle-to-vehicle communication, and highly accurate location-based services. The first Li-Fi equipment was developed by Professor Harald Haas and coined during a TED Global talk.

1. Let’s go towards bright future with a lightening speed………..
as coined by Prof.
Harald Haas during his TED
Global talk, is bidirectional, high
speed and fully networked
wireless communications, like Wi-
Fi, using light.
Li-Fi is a subset of optical
wireless communications and can
be a complement to RF
communication, Wi-Fi, cellular
network.
Underwater communications are easily and efficiently
possible.
Vehicle to vehicle and vehicle to roadside
communication.
Location based service with highly accuracy is
possible.
