Analysis of LiFi System Performance Considering Different Bit rates and Link Ranges

Abstract

With the growth in population, the number of devices connected to internet are expected to increase exponentially. The current wireless communication system which is based on radio frequency (RF) technology, is not able to satisfy the requirement of high speed data consumption due to limited spectrum availability and network congestion. In this paper we analyse the performance of LiFi communication system by employing an LED with 450 nm wavelength as optical source for communication using RZ-OOK modulation format. Performance of the system has been evaluated through Q factor and BER values for different bit rates and link ranges. The system can support 50 Mbps data rate upto 3.4 m of link range with a Q Factor of 10.71.
