Receiver and associated mobile communications device

An optical wireless communications receiver for a communications device, the optical wireless communications receiver being configured to receive optical radiation signals from different optical transmitting devices on which communication data is encoded, wherein:

• the communications device comprises a first surface and a second surface, and at least one of a perimeter edge or a perimeter side of the communications device which extends between the first surface and the second surface, wherein at least one of a perimeter or a periphery of the communications device extends around at least one of the perimeter edge or the perimeter side, and around the perimeter of at least one of the first surface or the second surface of the communications device;
• the optical wireless communications receiver is comprised at least one of in, on or configured for mounting to at least part of the perimeter edge or the perimeter side or a perimeter corner on the perimeter of the communications device;
• the optical wireless communications receiver comprises a plurality of optical receiver elements configured to receive the optical radiation signals and distributed over the optical wireless communications receiver such that in use when the optical wireless communications receiver is at least one of mounted to, comprised in or on the communications device, the plurality of optical receiver elements are distributed over at least one of the perimeter edge or the perimeter side and over a perimeter corner of the communications device or distributed over at least two or more of the perimeter edges, the perimeter sides or the perimeter corners of the communications device;
• wherein depending on a location of the optical wireless communication receiver at which the optical radiation signals from the different transmitting devices are received, at least one of the plurality of optical receiver elements is configured to receive a first optical radiation signal and at least one of the plurality of optical receiver elements is configured to receive a second different optical radiation signal, to at least one other of the plurality of optical receiver elements;
• and
• wherein the different optical radiation signal is an interfering optical radiation signal from a non-target optical transmitting device and the optical wireless communication receiver is configured to cancel, disregard, or remove signals from the optical receiver elements receiving the interfering optical radiation signal or to deactivate receiver elements most strongly receiving interfering optical radiation signals.
