High Speed Mode Division Multiplexing based Visible Light Communication for IoT Applications

Today, high bandwidth and high capacity optical wireless networks for internet of things application are growing. The economical light emitting diode (LED) basics visible light communication (VLC) is a fast growing optical wireless scenario. Thus, a high speed 12×20Gbps hybrid VLC and mode division multiplexing system considering laguerre-gaussian (LG)[00] and LG [01] modes is proposed. Two sets of six LEDs are used for signal transmission where each set operates at different LG modes. OptiSystem is incorporated to design and investigate the system performance at 10
⁻³
bit error rate. The results indicate that faithful VLC range of 30-50m is obtained successfully for LG[00] as well as LG [01] operating modes for red LED, with supportable 60 internet of things devices. The comparative analysis of the proposed design indicates its superiority over other existing ones. This system can be incorporated for future based high bandwidth next generation optical access networks.
