Patent ID: 8805397

Claim:
A method of mitigating interference in a mobile wireless communication device, the method by the mobile communication device comprising: estimating a performance impact to signals received in a first frequency band by a first transceiver of the mobile wireless communication device through a WLAN (wireless local area network) connection with a WLAN partner device from signals transmitted by a second transceiver of the mobile wireless communication device through a wireless cellular connection; determining whether the WLAN connection is in ad hoc mode in response to the estimated performance impact indicating that the signals transmitted by the second transceiver through the wireless cellular connection is interfering with the signal received in the first frequency band by the first receiver through the WLAN connection; determining that the WLAN connection is not in an ad hoc mode, and in response to the determination, further determining whether a proprietary communication is possible with the WLAN connection; determining that the proprietary communication is possible with the WLAN partner device, and in response to the determination, changing the WLAN connection to use a second frequency band, and communicating with the WLAN partner device using the proprietary communication; and repeating periodically the estimating, determining and changing steps while the WLAN and wireless cellular connections are active.
