20090310617 | Data Distribution by Proxy - A communication device communicates with an originating device during an originating session and receives originating data from the originating device over a wireless communication link and then communicates with a receiving device during a receiving session and sends the originating data to the receiving device over a wireless communication link, such that the originating session and the receiving session occur at different times, and at least one of the sessions is an ad hoc communication session. | 2009-12-17 |
20090310618 | Low Power Receiving - The disclosed methods of low power communications facilitate high speed reception of data from an access point (AP) with low transmission latencies while remaining in power save mode as long as possible. The disclosed methods allow the client to remain in a power save state and involve creating a synchronous client frame exchange with the AP that is independent of a digital traffic indication map and the AP's beacon interval. Two methods to accomplish this goal are disclosed: one which involves sending PS Poll Frames; and one that includes fast CAM switching, both at a self tuning frequency. | 2009-12-17 |
