Performance Evaluation of Visible Light Communication System Design in Indoor Scenario

Abstract

The successor of the fifth-generation (5G) cellular technology is the sixth-generation (6G) wireless communication network. It is one of the most anticipated technologies because the 6G network operates at considerably higher frequencies, has far greater capacity, and has much-reduced latency than 5G networks now do. Visible Light Communication (VLC) is a new technology in Optical Wireless Communication (OWC) that has the potential to become the communication medium for a 6G network through the visible light from Light Emitting Diode (LED) that can be implemented for indoor and outdoor communication systems. We have done simulations with the assumption that communication occurs indoors and uses the line of sight channel model. We also consider a high bit rate of up to 1 Gbps to meet future needs. For indoor VLC systems, the LED placement technique is very influential on the coverage of a room, and this research proposes designing VLC systems in a closed indoor room, measuring $5\times 5\times 3\ \mathrm{m}^{3}$. The computer simulation obtained the highest received power at −18 dBm with the best coverage link communication 1.88 m2 and receiver propagation distance to the transmitter at 2.397 m.
