Patent ID: 8532650

Claim:
An electronic device comprising: a host controller; a first radio coupled to the host controller, the first radio comprising a Wireless Local Area Network (WLAN) radio configured to operate in a first operating frequency region; and a second radio coupled to the host controller, the second radio comprising a Wireless Personal Area Network (WPAN) radio configured to operate in a second operating frequency region exclusive of the first operating frequency region; the first and second radios configured to employ time division multiplexing; and the host controller configured to: inform the second radio whenever the first radio requests operation at a proposed operating frequency region containing frequencies within the second operating frequency region; ensure that the second radio updates the second operating frequency region to exclude frequencies in the proposed operating frequency region, prior to allowing the first radio to probe for operation at the proposed operating frequency region; inform the first radio to probe for operation at the proposed operating frequency region, after receiving an acknowledgement from the second radio that the second operating frequency region has been updated; and instruct the second radio based on the result of the probe; the second radio configured to update, if the probe is successful, the second operating frequency region to comprise frequencies in the first operating frequency region; and the second radio configured to update, the second operating frequency region to reclaim the frequencies in the proposed operating frequency region if the probe is unsuccessful and the first radio cannot operate in the proposed operating frequency region.
