A master device selects a channel from a band of channels for communications with a slave device. The master transmits information identifying the selected to the slave device using a packet modulated as a series of energy pulses on the selected channel. The slave device performs wideband energy detection on the band of channels and receives the modulated pulses. The slave device decodes the modulated pulses to retrieve the selected channel, and tunes to the selected channel for further communications.
