ABSTRACT:
A first radio transceiver is operated in close proximity to a second radio transceiver, even when the first and second radio transceivers operate in accordance with incompatible standards. Operation in this manner includes receiving a first signal that indicates whether the second radio transceiver is idle or busy and receiving a second signal that, when the second radio transceiver is idle, indicates when the second radio transceiver must have access to a second channel. Operation includes determining whether to enable the first radio transceiver to use a first channel based at least on the first signal.
