Abstract: An optical wireless communication (OWC) enabled luminaire system comprises at least one radiation source; a driver apparatus configured to drive the at least one radiation source to produce modulated radiation comprising or representing an OWC signal; a plurality of outputs configured to output modulated light that comprises or is generated using the modulated radiation produced by the at least one radiation source, wherein the plurality of outputs are positioned at substantially different locations that are remote from the at least one radiation source; and at least one guide configured to guide the modulated radiation from the at least one radiation source to the plurality of outputs.
