The RF-enabled TempTale

During system installation, a channel is selected based on which channel offers the best signal-to-noise ratio. On power up, the Gateway scans the three channels transmitting a beacon.

The Repeater responds to the beacon and joins the network on the appropriate channel. If a Repeater loses contact with the Gateway during system operation, it listens for a beacon and reconnects to the network on that channel.

The Gateway periodically compares the signal-to-noise ratio on the current channel to the signal-to-noise ratios on the other channels. If the Gateway finds a better signal-to-noise ratio, it will transmit a beacon to the Repeaters to join the network on that channel.

The TempTale unit scans the same three channels and looks for a network. If one is not found, it sleeps for another cycle. If a network is found, it remains on the channel and waits to be downloaded. The signal used is a narrow band that transmits at +3 dBm. The channel width is 185 kHz, with 99 percent of energy within this channel.
