摘要： Methods and apparatus for reduction of interference between a plurality of wireless interfaces. In one exemplary embodiment, a device having a first (e.g., Wi-Fi) interface and a second (e.g., Bluetooth) interface monitors interference between its interfaces. A reduction in transmit power of the Wi-Fi module causes a disproportionately larger reduction in undesirable interference experienced at the Bluetooth antennas. For example, when the Bluetooth interface detects interference levels above acceptable thresholds, the Wi-Fi interface adjusts operation of one or more of its transmit chains based on various conditions such as duty cycle, Received Signal Strength Indication (RSSI), etc. Various embodiments of the present invention provide simultaneous operation of WLAN and PAN interfaces, without requiring time division coexistence, by reducing power on a subset of interfering antennas.

摘要： Methods and apparatus for enhancing network capacity in a network comprising multiple wireless communication that overlap at least partly in frequency spectrum. In one embodiment, the apparatus comprises a portable device such as a laptop or smartphone having both a WLAN (e.g., Wi-Fi) interface and a PAN (e.g., Bluetooth) interface which each operate with approximately the same frequency range. One variant places the WLAN interface into a power-saving mode as a default, thereby mitigating interference with the PAN interface in cases where the WLAN interface is not in active use. In another variant, an aggressive PAN management algorithm is used to enforce network policy on the PAN interface, thereby mitigating interference between the PAN interface and the WLAN interfaces of other devices in the network (as well as the parent device). AP-based variants are also described. Methods of operation and doing business utilizing the aforementioned apparatus are also disclosed.

摘要： 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.

摘要： Methods and apparatus for compensating for the effects of interference between multiple wireless communication apparatus. In one embodiment, the method comprises providing a first wireless communication apparatus operating in a first band and a second wireless communication apparatus operating at least partly in the first band, where the second wireless communication apparatus operates according to a different communication protocol than the first wireless communication apparatus. Interference is compensated for between the first wireless communication apparatus and the second wireless communication apparatus by selecting and operating according to one of a plurality of operational protocols. In another embodiment, the first wireless communication apparatus and the second wireless communication apparatus operate in a closed-loop relationship to cooperatively compensate for communication interference.
