Claim 18:
19. A hub station comprising:
a memory; and
a processor coupled to the memory, the processor configured to:
monitor a first channel activity level associated with a first channel of a plurality of channels within a particular frequency range, wherein the hub station communicates with a device using the first channel;
determine that the first channel activity level satisfies a threshold activity level;
switch to a second channel of the plurality of channels to communicate with the device, at least in part, in response to determining that the first channel activity level satisfies the threshold activity level; and
notify the device that the hub station switched to the second channel by sending an acknowledgment message to the device on the second channel in response to receiving a message from the device on the second channel, wherein the message is sent to the hub station on the second channel after at least one unsuccessful attempt to send the message to the hub station on the first channel.
