LiFi uses light to transmit data, while WiFi uses electromagnetic waves at radio frequencies to transmit data. Due to the low interference caused by light compared to radio frequency waves, it is used in denser environments.

LiFi is a wireless optical network technology that uses light-emitting diodes to transfer data. LiFi is designed to use LED lamps similar to those currently used in many energy-efficient homes and offices.

Li-Fi is a wireless communication technology that uses light to transmit data and locations between devices. The term was first introduced by Harald Haas during the 2011 TEDGlobal talk in Edinburgh.

LiFi can transmit up to 100 Gbps and maybe more, but this will require a change in lighting technology. The latest news report that LiFi is 100 times faster than WiFi. The average Wi-Fi speeds were supposed to be 10 Mbps and the LiFi speed could reach 1 Gbps.

For example, in corridors, waiting rooms, patient rooms and operating theaters, Li-Fi technology will allow a light communication network, which will eliminate electromagnetic interference problems from smartphones and use of hospital Wi-Fi.
