An apparatus for use in an optical wireless communication, OWC, system , the apparatus comprising: - a wide beam light source (L5); - two or more narrow beam light sources (L1-L4) each configured to emit in a different direction, wherein a combined field-of-view, FoV, of the narrow beam light sources (L1-L4) is covered by a FoV of the wide beam light source (L5); - a plurality of switches (S1-S5) each configured to turn on or off a corresponding one out of the wide beam light source (L5) and the two or more narrow beam light sources (L1-L4) individually; - a receiver (RX) configured to receive one or more feedback signals from a remote device ; and - a controller (CTR) configured to: o control the plurality of switches (S1-S5) via a control signal; o update the control signal based on the one or more feedback signals received by the receiver (RX); o carry out a beam selection procedure by sending test signals via the wide beam light source (L5) and one or more narrow beam light sources (L1-L4) to the remote device to enable a selection of one out of the narrow beam light sources (L1-L4) for establishing data communication with the remote device , characterized in that the controller is configured to, during the beam selection procedure, set the control signal to: - turn on the wide beam light source (L5); and simultaneously, - turn on at most one of the narrow beam light sources (L1-L4); and wherein the wide beam light source (L5) and the receiver are configured to maintain a low speed bi-directional signaling link with the remote device to assist the beam selection procedure. - a wide beam light source (L5); - two or more narrow beam light sources (L1-L4) each configured to emit in a different direction, wherein a combined field-of-view, FoV, of the narrow beam light sources (L1-L4) is covered by a FoV of the wide beam light source (L5); - a plurality of switches (S1-S5) each configured to turn on or off a corresponding one out of the wide beam light source (L5) and the two or more narrow beam light sources (L1-L4) individually; - a receiver (RX) configured to receive one or more feedback signals from a remote device ; and - a controller (CTR) configured to: o control the plurality of switches (S1-S5) via a control signal; o update the control signal based on the one or more feedback signals received by the receiver (RX); o carry out a beam selection procedure by sending test signals via the wide beam light source (L5) and one or more narrow beam light sources (L1-L4) to the remote device to enable a selection of one out of the narrow beam light sources (L1-L4) for establishing data communication with the remote device , o control the plurality of switches (S1-S5) via a control signal; o update the control signal based on the one or more feedback signals received by the receiver (RX); o carry out a beam selection procedure by sending test signals via the wide beam light source (L5) and one or more narrow beam light sources (L1-L4) to the remote device to enable a selection of one out of the narrow beam light sources (L1-L4) for establishing data communication with the remote device , characterized in that the controller is configured to, during the beam selection procedure, set the control signal to: - turn on the wide beam light source (L5); and simultaneously, - turn on at most one of the narrow beam light sources (L1-L4); - turn on the wide beam light source (L5); and simultaneously, - turn on at most one of the narrow beam light sources (L1-L4); and wherein the wide beam light source (L5) and the receiver are configured to maintain a low speed bi-directional signaling link with the remote device to assist the beam selection procedure. <EOS>
