In order to achieve to achieve the short distance communication the currently using technology such as Bluetooth and Wi-Fi fails to deliver the data with larger bandwidth and greater data rate. Visible light acts as comparable to the present wireless radio frequency communication by achieving larger bandwidth and high data rate. Because with larger frequency spectrum it is possible to provide a greater portion of the bandwidth to each user to shift information. A switching LED can be improbably causing annoyance, but data can there-fore be encoded in the light by varying the rate at the LEDs switch on and off to provide various strings of 1’s and 0’s. Hence the given data can be converted into binary format before transmission. The digital transmission has more advantages compared to the analog communication. The advantages of the Li-Fi are it has high data rates of about 10 Gbps. It has high security as light can’t penetrate into walls. The applications are indoor broadcasting of information such as hospital management, industrial applications like communication inside the Aeroplan.

Bluetooth, radio frequency communication, Visible Light Communication (VLC), high data rate, larger bandwidth.
