Li-Fi Amplified: Industrial Connectivity through Distributed MIMO

Abstract

We have embedded billions of things and made it possible to continuously share data across numerous applications in the framework of IoT. This indicates that OWC can likely help fill prevailing RF-based networks' gaps, such as spectrum scarcity and signal attenuation. OWC employs visible light, infrared or ultraviolet spectrum to convey information, which has the following advantages: large bandwidth, energy consumption, and enhanced security. Thus, this article elaborates on a distributed multi-user MIMO for mobile devices supported by optical wireless infrastructure. The system comprises a base unit connected to several dispersed and more extensive optical front ends. This integration intends to establish a MIMO-VLC system by properly integrating several antennas with possible VLC-incorporated devices, including LED lights. MIMO spatial diversity is employed to increase the data rates and connection reliability by freeing from interference and signal fading and reducing the consequences of fading. Because of this uniqueness, the visible light spectrum can be used as a substitute in cases where everyday radio-frequency-based communication is challenging or prohibited.
