摘要： A method and system for adapting low noise amplifier gain comprise determining a Bluetooth received signal strength indication of Bluetooth signals transmitted by a Bluetooth peer; determining a WLAN received signal strength indication of WLAN signals transmitted by a WLAN peer; comparing the Bluetooth received signal strength indication to a predetermined Bluetooth signal strength threshold to determine a Bluetooth peer distance of the Bluetooth peer; comparing the WLAN received signal strength indication to a predetermined WLAN signal strength threshold to determine a WLAN peer distance of the WLAN peer; and controlling a gain of a low noise amplifier to be applied to the Bluetooth signals and the WLAN signals based on the Bluetooth peer distance and the WLAN peer distance. In a further embodiment, the gain may be controlled by using a bypass signal to place the low noise amplifier into at least one of (a) a bypass mode in which the Bluetooth signals and the WLAN signals pass through the low noise amplifier without the gain being applied, and (b) a fixed gain mode in which the gain is applied to the Bluetooth signals and the WLAN signals. In another embodiment, the gain may be controlled by using the bypass signal to control an internal WLAN low noise amplifier and an internal Bluetooth low noise amplifier.

摘要： A beginning of a Bluetooth inquiry phase or a Bluetooth paging phase is determined. In response to determining that the Bluetooth inquiry phase or the Bluetooth paging phase is beginning, a power save (PS) mode signal is sent from a first device to a second device via a wireless local area network (WLAN) communication link, wherein the PS mode signal indicates that the first device is in a WLAN PS mode. A PS poll signal is sent from the first device to the second device via the WLAN communication link in a gap between Bluetooth inquiry phase message transmissions during the Bluetooth inquiry phase or between Bluetooth paging phase message transmissions during the Bluetooth paging phase.

摘要： Quality of service for mesh networks is described. In embodiment(s), communication data can be prioritized as priority data and/or non-priority data for communication from a source node to a destination node in a mesh network. A first communication route in the mesh network can be determined to communicate the priority data from the source node to the destination node based on a minimum number of intermediate nodes via which the priority data is communicated. Additionally, a second communication route in the mesh network can be determined to communicate the non-priority data from the source node to the destination node based on a highest bit rate to communicate the non-priority data. A time duration to communicate the priority via the first communication route is less than a time duration to communicate the non-priority data via the second communication route.

摘要： An apparatus has first and second wireless communication modules with respective first and second wireless communication signaling terminals. An arbiter is coupled to receive a request for access to an antenna from one of the first and second wireless communication modules. The arbiter is operable to cause the antenna to be coupled to one of the first and second wireless communication signaling terminals in response to the request, and a coexistence module is operable to prevent the arbiter from receiving a request from the second wireless communication module to thereby allow a communication of the first wireless communication module.
