Claim 19:
20. A non-transitory computer-readable medium comprising instructions that, when executed by a processor within a hub station, causes the processor to perform operations comprising:
monitoring 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;
determining that the first channel activity level satisfies a threshold activity level;
switching 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
notifying 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.
