Patent ID: 8412263

Claim:
A method, comprising: operating a first radio in a first coexistence mode between the first radio and a second radio; while in the first coexistence mode, receiving at the first radio from a coexistence controller a first signal on a first line to determine which channel of the second radio is being used by the second radio or that the second radio is active and should be given priority; sending to the coexistence controller from the first radio a second signal on a second line to synchronize the second radio with the first radio or to indicate the first radio is active and priority should be given to the first radio; and monitoring at the first radio a third signal received on the first line from the coexistence controller to determine if a third radio is active, the third signal being different from the first signal; in the event the third radio is active, switching the first radio to a second coexistence mode between the first radio and the third radio and operating the first radio in the second coexistence mode, while in the second coexistence mode, receiving at the first radio from the coexistence controller a fourth signal on a third line indicating that activity of the third radio is occurring and that first radio can be synchronized to start and stop first radio communications to accommodate third radio activity.
