摘要： A radio receiver is described that processes multiple wireless standards using a single antenna according to embodiments of the invention. The radio receiver includes a single antenna, and a low noise amplifier that is connected to the antenna, without an intervening power divider or power splitter. The output of the low noise amplifier feeds multiple wireless receivers in a parallel arrangement that are operating according to different communications standards, including for example a Bluetooth receiver, and a WLAN 802.11 receiver. Additional wireless standards and their corresponding receivers could be added as well. The input impedance of the low noise amplifier defines the impedance seen by the antenna, regardless of which operational standard is actually in use. Since the input impedance of the low noise amplifier is substantially independent of whether the Bluetooth or WLAN paths are ON or OFF, simultaneous operation can be accomplished.

摘要： Certain embodiments of the invention may be found in a method and system for antenna and radio front-end topologies for a system-on-a-chip (SOC) device that combines Bluetooth and IEEE 802.11 b/g WLAN technologies. A single chip radio device that supports WLAN and Bluetooth technologies receives a WLAN signal in a WLAN processing circuitry of the radio front-end and in a Bluetooth processing circuitry of the radio front-end. Signals generated by the WLAN processing circuitry and the Bluetooth processing circuitry from the received WLAN signal may be combined in a diversity combiner that utilizes selection diversity gain combining or maximal ratio combining (MRC). When a generated signal is below a threshold value, the signal may be dropped from the combining operation. A single antenna usage model may be utilized with the single chip radio device front-end topology to support WLAN and Bluetooth communications.

摘要： A host device may be enabled to support a plurality of wireless interfaces, wherein some of these interfaces may be utilized to support human interface device (HID) based communication. The host device may be enabled to monitor activity of HID devices based on communications via HID capable wireless interfaces, may predict future use of the HID devices based on the monitoring, and may manage sniff communication that is utilized to track and/or detect activities in the HID devices. The management of the sniff communication may comprise adjusting characteristics of the sniff communication to enable improving throughput of other wireless interfaces available via the host device that may be affected by the sniff communication. The adjustment of the characteristics of sniff communication may comprise adjusting, statically and/or dynamically, length of sniff intervals and/or designating of sniff packets as high priority requests.
