Abstract
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.

The conference focuses on leading edge research on Optical Wireless Communication in its different forms and gathers experts from academia and industry to show their latest technical results and showcase their products and services. The application scope is broad and it ranges from Ultra-short range to Ultra-long range.

Conference topics cover visible light communication, infrared optical and ultraviolet communication. These different forms of OWC can potentially be employed in a diverse range of communication applications ranging from optical interconnects within integrated circuits through outdoor inter-building links to free-space satellite communications.

The following topics are being covered during the conference:

• Ultra-short range: for instance chip-to-chip communications in stacked and closely packed multi-chip packages
• Short range: For instance wireless personal area network (WPAN) applications under standard IEEE 802.15.7 and underwater communications.
• Medium range: indoor IR and visible light communications (VLC) for wireless local area networks (WLANs) and inter-vehicular and vehicle-to-infrastructure communications.
• Long range: inter-building connections, also called free-space optical communications (FSO).
• Ultra-long range: Laser communication in space especially for inter-satellite links and establishment of satellite constellations

This paper was presented during the conference which took place during the Photonics Applications Week.
