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 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 dynamically compensating for the effects of interference between multiple wireless communications 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 in the same first band (or proximate to the first band and with a comparatively high transmitter power), where the second wireless communication apparatus operates according to a different communication protocol than the first wireless communication apparatus and further change in physical configuration with respect to one another. Based on the physical configuration, interference is compensated for between the first wireless communication apparatus and the second wireless communication apparatus “on the fly” by selecting and operating according to one of a plurality of operational protocols.

摘要： Methods and apparatus for optimizing wireless network performance by incorporating platform configuration and use case information. In one exemplary scheme, a client device provides the wireless network with an indications of impacted operations based on the client device's platform configuration. The wireless network can adjust the radio link to the client device so as to best accommodate the impacted operation. In one embodiment, a client device that includes a 3×3 Wireless Local Area Network (WLAN) (or 4×4, 2×2, etc.) and Bluetooth (BT) module identifies a subset of modulation and coding schemes (MCS) that are preferred for operation. The client device provides the identified subset to the WLAN access point (AP). Responsively, the WLAN AP selects a MCS, such that the client device's overall performance remains at an acceptable level. In another embodiment, the server/client can adjust MCS and/or active antenna chains based on the noise floor (NF) level.

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 analysis of electronic components such as radio transceivers (for example, WLAN, Bluetooth, cellular, GPS). In one embodiment, a “black box” is diagnosed in its final device application and layout, using a series of software test routines or suites. The test suites provide simultaneous monitoring of multiple non-overlapping status indicators. Each test suite can be selectively enabled or disabled, and may also provide runtime modification of one or more parameters, and or intelligent testing of system operation. In another embodiment, multiple black box modules within a single form factor device are simultaneously run; the interference levels between the black box modules (as well as other parameters) are independently measured, displayed and logged to the user. Exemplary embodiments are described in reference to a Bluetooth module and WLAN module operating within a spatially restricted device (such as a desktop/laptop computer, “smartphone”, Bluetooth mouse and keyboard).
