Optical wireless communication system and adaptive optical wireless communication network

A full-duplex communication system, comprising:

• a plurality of network members, each one comprising at least one first communication interface adapted to communicatively couple to any other one of the of said plurality of network members and at least one user device via optical wireless communication (OWC);
• at least one gateway member, comprising at least one second communication interface adapted to communicatively couple to any one of said plurality of network members via optical wireless communication (OWC), said at least one second communication interface is further adapted to communicatively couple to at least one external communication network;
• at least one portable access member, operably connectable to a user device and comprising at least one third communication interface adapted to communicatively couple said user device to any one of said plurality of network members via optical wireless communication (OWC), and
• wherein said communication system is adapted to form any one of a duplex ring network topology and a duplex mesh network topology, utilising said plurality of network members and said at least one gateway member;
• characterized in that, the at least one portable access member is a user access dongle connected to a user device, wherein the user device is a smart device and one or more of said at least one gateway member is adapted to control any one of said plurality of network members, wherein the gateway member provides a unique id and address to each network member and the network member starts transmitting a beacon, the portable access member captures the beacon and performs CSMA-CA (Carrier Sense Multiple Access-Collision Avoidance) for association, so as to determine at least one data communication path to the at least one user device.
