Method and system for a dual modulation low data rate network

摘要

A dual modulation network is disclosed. The dual modulation network includes a primary network hub (PNH) having a PNH Long range transceiver and a PNH microcontroller. The PNH microcontroller has communication firmware for long range spread spectrum (SS) and narrowband frequency shift keying (FSK) signal communication via the PNH Long range transceiver, and includes a PNH clock signal. The dual modulation network also includes a peripheral device (PD). The PD includes an actuation mechanism, a PD Long range transceiver, and a PD microcontroller. The PD microcontroller has actuation firmware, communication firmware for communication via the PD Long range transceiver, and location firmware, and includes a clock signal. The location firmware instructs the PD long range transceiver to transmit a location signal encoded with a PD transmit time stamp notifying a receiving device of the time the PD transmitted the location signal.
