Photometric Analysis in Designing 5G Enabled Smart Indoor-Campus Network Using VLC

In recent decades, there has been a notable surge in interest surrounding visible light communication (VLC), which utilizes visible light as a means of transmission. LEDs have emerged as the preferred light source for VLC due to their rapid switching rate, energy efficiency, and modulation capabilities. Despite the widespread use of radio frequency bands in modern communication systems, VLC stands out for its broad coverage and minimal interference. This research aims to create an energy efficient lighting model for a VLC network and conduct a photometric and financial analysis of the current lighting system. To verify the technical aspects of the LED performance, the DIAlux Evo software is used to redesign and simulate the lighting system. Simulation shows that 12 LED lights in a regular classroom provide the desired illumination levels with an average efficiency of 468 lx and a lighting power density of 5. 57 W/m 2 . After conducting a photometric analysis, a detailed financial assessment is performed to evaluate total power consumption and annual energy expenditure. This involves considering all Fluorescent Lights (FL) and proposing their replacement with LEDs for energy savings. By implementing LEDs, 70% of the cost can be reduced and the average efficiency of 126.4 lm/W can be maintained with CRI value > 80 and CCT as 4000K. Moreover, LED based VLC model is designed by Optisystem for the indoor environment to examine the data rate within 5 <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">m</tex> and this model can transmit data with maximum of 30 Mb/s. This LED-based lighting setup will be used for a 5G-enabled VLC setup.
