Free Space Optics and Radio Frequency Signals in Spacial Communication

Light as a medium to transmit Data is used in LiFi Technology. LiFi is a wireless communication system which makes use of Free Space Optics to transmit and receive data instead of traditional radio frequency as in WiFi. This paper gives a comparison between Free Space optics and Radio Frequency wireless communication signals in terms of efficiency, transmission rate and capacity in Space communication. It gives the introduction to Hybrid System which can be used in Spatial Communication.
