A system and method for detecting and receiving packets that are transmitted over a network that utilizes a plurality of channels is disclosed. The system includes a radio circuit, which can be configured to receive packets over a plurality of channels, a processing unit, and a memory in communication with the processing unit. The processing unit loads a set of operating parameters in the radio circuit, which enables the radio circuit to detect and receive packets on a particular channel. If a preamble is not detected within a predetermined time period, the system hops to a different channel by loading a second set of operating parameters in the radio circuit. This process can be repeated for an arbitrary number of channels.

Software emulation of parallelized packet detection across channels

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.

System and method for low power Z-wave beaming detection

A system and method of allowing a new device to join an existing network are disclosed. The new device comprises a non-RF-based transmitter, such as a light, a speaker or haptic generator, which emits a sequence that can be received by a facilitator device that is already part of the network. The sequence contains the device specific information associated with the new device. This facilitator device may be a mobile phone, a tablet or other component. The facilitator device then provides this device specific information to the gateway. The gateway then uses this device specific information as it performs a joining process with the new device.
