20090257379 | Methods and apparatus for network capacity enhancement for wireless device coexistence - 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. | 10-15-2009 |

20120074988 | ELECTRONIC DEVICE WITH DYNAMIC DRIVE STRENGTH ADJUSTMENT TO MITIGATE IMPACT OF SYSTEM NOISE ON WIRELESS PERFORMANCE - Electronic devices such as portable computers may contain circuits that generate radio-frequency noise. The radio-frequency noise may interfere with the operation of sensitive circuitry such as wireless communications circuitry. The circuits that generate the radio-frequency noise may include differential signal drivers that drive signals onto communications lines such as lines in a bus or output interface. A control circuit may power the drivers at an adjustable driver voltage bias level. The amount of noise that is generated by the drivers may vary as a function of the voltage bias level and may produce different amounts of noise at different wireless frequencies. Computer lid position and other factors may also influence the amount of interference that is generated. The control circuit may determine the current operating state of the device and may make voltage bias level adjustments that minimize interference between the drivers and the wireless circuitry. | 03-29-2012 |
20120207032 | METHODS AND APPARATUS FOR WIRELESS COEXISTENCE BASED ON TRANSCEIVER CHAIN EMPHASIS - 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. | 08-16-2012 |
