Patent ID: 8238831

Claim:
A method of mitigating interference in a mobile wireless communication device, the method comprising: estimating a performance impact to signals received by a first transceiver of the mobile wireless communication device through a Bluetooth connection that uses a first frequency band from signals transmitted by a second transceiver of the mobile wireless communication device through a wireless cellular connection; changing the Bluetooth connection to exclude a portion of the first frequency band used by the first transceiver based on the performance impact estimation; and repeating periodically the estimating and changing while the Bluetooth and wireless cellular connections are active; wherein the first frequency band of the Bluetooth connection used by the first wireless transceiver is separate from a second frequency band of the wireless cellular connection used by the second wireless transceiver; and wherein higher order harmonics of transmissions in the second frequency band of the wireless cellular connection output by the second transceiver overlap at least a portion of the first frequency band of the Bluetooth connection received by the first transceiver; and wherein estimating the performance impact to signals received by the first transceiver through the Bluetooth connection by signals transmitted by the second transceiver through the wireless cellular connection depends on a power level of signals transmitted by the second transceiver, an amount of radio frequency antenna isolation between the first and second transceivers, and a receiver sensitivity requirement of the first transceiver.
