Question :

Differentiate between LiFi and WiFi technologies.

Basic difference between LiFi and WiFi technologies are:

1. LiFi stands for Light Fidelity and WiFi stands for Wireless Fidelity.
2.  LiFi Uses light as medium for data communication with the help of LED bulbs where as WiFi uses Elecro-magnetic waves at various radio frequencies for data communication withthe help of WiFi router.
3. LiFi is an optical communication technology where as WiFi is a radio communication technology.
4. LiFi do not have any intereference issues similar to radio frequency waves where as WiFi will have intereference issues from nearby access points(routers).
5. In LiFi, light does not pass through the walls and hence will provide a much secure data trasfer.
   In WiFi, RF signal passess through the walls and hence there is a need to employ techniques to achieve secure data transfer.
