Claim 15:
16. A network for determining the location of a beacon, the network comprising a plurality of electronic devices, which are spaced apart and distributed over an enclosed area or volume such as a building;
wherein each electronic device comprises:
a lighting device, capable of illuminating a room or the like;
a photodetector;
an ultra-wideband (UWB) pulse transmitter;
a UWB pulse receiver;
a controller, adapted for encoding a signal and transmitting the signal to the lighting device and/or to the pulse transmitter, and for decoding a signal received by the photodetector or the pulse receiver;
wherein the lighting device is adapted to transmit the signal as a LiFi signal and the pulse transmitter is adapted to transmit the signal as a UWB signal, and wherein the controller is configured for multiplexing, encoding/decoding and generating data simultaneously as LiFi and UWB signals,
wherein the network further comprises a central processor, connected via wired or wireless communication to the plurality of electronic devices and adapted to determine a position of the beacon relative to the positions of the plurality of electronic devices, by means of LiFi and/or UWB signals transmitted from the beacon to the plurality of electronic devices or vice versa.
