Abstract
Method, apparatus and computer program for broadcasting a synchronization signal as a timing reference for slave devices; broadcasting by an impulse radio transceiver a discovery request packet with a given timing offset with relation to the timing reference, for reception by receptive slave devices with matching timing with the given timing offset; receiving by the impulse radio transceiver a response packet from each receptive slave device with the given timing offset; and detecting a timing conflict in which the impulse radio transceiver has simultaneously received two or more response packets, and responsively transmitting by the impulse radio transceiver to the receptive slave devices a response change request packet; the response change request packet requesting one or more of the receptive slave devices to cease sending response packets in response to a following discovery request packet sent with the given timing offset.
