Abstract:
A system and method for detecting and receiving Z-Wave Beams that are transmitted over a plurality of channels is disclosed. The system includes a radio circuit, which includes a Digital Signal Arrival (DSA) circuit and a read channel. The DSA circuit is able to detect the presence of a valid signal on a particular channel, based on received signal power, detected frequency deviation, the magnitude of phase spikes and/or other characteristics. The read channel is able to decode incoming packets. Software is used to control the DSA circuit and the read channel so that, during each wake up period, the FLiRS device monitors all available channels to determine if a Z-Wave Beam is present. If a Z-Wave Beam is detected, the read channel receives the Z-Wave Beam. Otherwise, the FLiRS device returns to sleep mode.
