摘要： A system and method for use of a short beacon in a wireless communication network is disclosed. In one embodiment, the method comprises generating a short beacon comprising PHY information, wherein the short beacon excludes MAC information and transmitting the short beacon via the wireless network. In general, three types of short beacons are disclosed, a first type consisting only of a PHY preamble, a second type also including a PHY header, and a third type also including a MAC header. In addition, the scheme of common beacons and individual beacons is described. Common beacons are broadcast omni-directional at the beginning of each superframe with low data rate and individual beacons are unicast to individual devices directionally with high data rate. A common beacon contains information intended for all of the devices of the network. An individual beacon contains information intended for one particular device.

摘要： A system and method for wireless communication of uncompressed media data having media data packet synchronization are disclosed. One embodiment of the system includes a source configured to transmit media data packets such that they propagate over a wireless channel and at least one sink configured to receive the media data packets over the wireless channel from the source. The media data packets are spaced apart from one another by at least one interleaved time. The system is configured to detect propagation of the media data packets, and to determine propagation delays of the media data packets. The source is further configured to determine a jitter between the media data packets based on the determined propagation delays. The source is further configured to adjust the transmission of the media data packets in response to the determination of the jitter.

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.
