Wireless interference mitigation

A mobile wireless communication device, comprising:

• a first transceiver configured to receive signals through a WLAN (wireless local area network) connection with a WLAN partner device;
• a second transceiver configured to transmit signals through a wireless cellular connection;
• and
• a control processor coupled to the first and second transceivers, wherein the control processor is configured to mitigate interference in the mobile wireless communication device by:
• estimating a performance impact to signals received by the first transceiver from signals transmitted by the second transceiver;
• determining whether the WLAN connection is in ad hoc mode in response to the estimated performance impact indicating that the signals transmitted in a first frequency band 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 a 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.
