1. An optical wireless communication (OWC) interface apparatus comprising:
at least one of an input or output configured to transfer data signals at least one of from or to a bus device;
optical interface circuitry configured to transfer OWC signals representative of the data signals between the OWC interface apparatus and at least one of a light transmitter apparatus or light receiver apparatus, wherein at least one of the light transmitter apparatus or light receiver apparatus is configured to at least one of transmit or receive the OWC signals as free space light signals; and
interface control circuitry that is configured to at least one of establish or maintain communication with the bus device in accordance with a bus protocol thereby to enable transfer of the data signals between the OWC interface apparatus and the bus device,
wherein the interface control circuitry is configured to control operation of at least one of the optical interface circuitry, the light transmitter apparatus or the receiver apparatus to at least one of establish or maintain optical wireless communication with a remote device using the free space light signals, and
wherein the remote device comprises a mobile device and at least one of:
the interface control circuitry is configured to monitor quality of communication with the remote device or to at least one of select or vary at least one operating parameter in order to maintain communication with the remote device; or
the interface control circuitry is configured to select at least one operating parameter in dependence on at least one property of the remote device.
