Abstract:
1. A wireless transceiver used within a system for monitoring remote devices, said wireless transceiver comprising: an RF transceiver for communicating in a spread-spectrum communication protocol and a fixed-frequency communication protocol, the RF transceiver comprising: a spread-spectrum communication protocol chipset for communicating in a first modulation scheme at a first radiating-power level; and a fixed-frequency communication protocol chipset for communicating in a second modulation scheme at a second radiating-power level; a data controller coupled to the RF transceiver for processing data communicated by the RF transceiver; and a memory comprising spread-spectrum logic implemented by at least one of the data controller and the RF transceiver, the spread-spectrum logic configured to: prepare a preamble portion and a data portion of a transmit-communication frame, the preamble portion comprising a first data channel index indicative of a first data channel frequency for communicating the data portion of the transmit-communication frame; transmit the preamble portion of the transmit-communication frame at a first frequency channel; and transmit the data portion of the transmit-communication frame at the first data channel frequency, and wherein the memory further comprises fixed-frequency logic implemented by at least one of the data controller and the RF transceiver, the fixed-frequency logic configured to: prepare a preamble portion and a data portion of a fixed frequency communication frame; and transmit the preamble portion and the data portion at a fixed-frequency designated channel frequency.
