Abstract
An optical wireless communication (OWC) transceiver apparatus includes at least one light transmitter configured to transmit light of a first wavelength or first range of wavelengths, driver circuitry configured to receive a data signal and to process the data signal to produce a driving signal to drive the at least one light transmitter such that the at least one light transmitter produces a modulated optical signal representative of said data signal, at least one photodetector configured to receive light of a second wavelength or second range of wavelengths and to produce a detection signal in response to the received light, receiver circuitry configured to receive and process the detection signal to produce a receiver signal, and demodulation circuitry configured to perform a decoding and/or demodulation process in accordance with an OWC protocol thereby to extract data from the receiver signal.
