WDM over POF for D-MIMO LiFi system

Optical Wireless Communication (OWC) is an important alternative option that could ease the pressure on the radio spectrum that is now in use for communication. There are several OWC technologies that offer a promising solution for indoor wireless broadband communication over a distance up to a few meters. Potentially, OWC is suitable for very high bandwidth communication over these distances. In addition, a Distributed Multiple-Input and Multiple Output (D-MIMO) concept for indoor communication is increasingly important not just to increase the total network throughput and reliability but also to provide a consistent link performance for high mobility and high user densities. Using POF, this D-MIMO concept can relatively easily be accommodated by using either multiple fibres with spatial division multiplexing [2] or by a single fibre with multiple colours or wavelength division multiplexing [3]. In this work, we propose a concatenation of WDM over POF and Distributed MIMO LiFi to combine them into one elegant solution to deliver high data rates and high Quality of Service (QoS) to the users.
