Optical wireless communication transceiver system

An Optical Wireless Communication, OWC, transceiver system, comprising:

• an optical receiver with at least a photodetector and a Trans-Impedance Amplifier, TIA, for amplifying the signal from the at least one photodetector, and
• a two-dimensional array of optical transmitters each having an individual transmitter field-of-view, and corresponding drivers,
• the two-dimensional array arranged to create a combined transmitter field of view that is larger than the individual transmitter field of view, the plurality of optical transmitters arranged such that optical axes of the plurality of optical transmitters are evenly distributed within the combined transmitter field of view;
• a baseband unit configured to modulate outgoing data for transmission by the optical transmitters and to demodulate incoming data from the output of the transimpedance amplifier of the optical receiver;
• a beacon generator configured to generate beacons for output by each respective one of the plurality of optical transmitters, wherein the beacon of a respective one of the plurality of optical transmitters comprises an attribute uniquely identifying the respective optical transmitter and wherein the beacons are transmitted out-of-band from the outgoing data;
• and
• a controller configured to:
• detect a presence of a first attribute of an optical transmitter from a potential communication partner in a beacon received at the OWC transceiver system in the output of the TIA;
• output feedback on the detected first attribute in the beacons of all of the plurality of optical transmitters;
• and
• detect a presence of a second attribute of one of the plurality of optical transmitters of the OWC transceiver system in feedback from a potential communication partner in a beacon received at the OWC transceiver system in the output of the TIA;
• and select which subset of the plurality of optical transmitters in addition to its beacon also transmits the outgoing data from the baseband unit based on the second attribute.
