摘要： The present invention provides a method and a system for device discovery in wireless communication. One implementation involves scanning one or more wireless channels to discover a partner wireless station for a new transmission, by detecting peak energy and beacons on each scanned channel. If a beacon is not detected, then selecting the clearest channel among the scanned channels, and transmitting beacons on the clearest channel. Upon detecting a beacon from a partner station, establishing association with the partner station and selecting a wireless data channel for communication with the partner station. Another implementation involves discovering a partner wireless station to establish a data channel for communication with a discovering station that is associated with a coordinator station, and transmitting a bandwidth reservation request to the coordinator to reserve channel time for control message exchange between the discovering station and the partner station.

摘要： A system implementing a method for multi-band wireless communication packetizes a block of source video information into a first packet, and packetizes the block of source video information into a second packet corresponding to the first packet, wherein the first packet and the second packet include corresponding video information. The first packet and the second packet are transmitted from a transmitting multi-band wireless station comprising a first radio for communication over a first wireless band, and a second radio for communication over a second wireless band. The first packet is transmitted over the first wireless band and the second packet is transmitted over the second wireless band. The first wireless band operates at a higher transmission rate than the second wireless band. A multi-band receiving wireless station reconstructs the source video based on packets arriving on different bands.

摘要： A high accuracy clock synchronization mechanism between a sender and a receiver in a communication network achieves time synchronization using broadcast beacons, directly at the PHY/MAC layer of the sender and the receiver, to minimize synchronization delay jitter. This provides a more efficient synchronization method than either NTP or SNTP, because multiple handshaking information exchange is avoided. Further, using beacons avoids the overhead of introducing additional synchronization packets in higher layer synchronization.
