Abstract
Methods and apparatus for mitigating the effects of interference between multiple air interfaces located on an electronic device. In one embodiment, the air interfaces include a WLAN interface and PAN (e.g., Bluetooth) interface, and information such as Receiver Signal Strength Index (RSSI) as well as system noise level information are used in order to intelligently execute interference mitigation methodologies, including the selective application of modified frequency selection, variation of transmitter power, and/or change of operating mode (e.g., from multiple-in multiple-out (MIMO) to single-in, single-out (SISO)) so as to reduce isolation requirements between the interfaces. These methods and apparatus are particularly well suited to use cases where the WLAN interface is operating with high data transmission rates. Business methods associated with the foregoing technology are also described.
