摘要： A method and system for data communication in a wireless network is provided. A wireless transmitter transmits a locality check message from a wireless transmitter to a wireless receiver over a wireless communication medium. Upon receiving a locality check response message from the wireless receiver, the wireless transmitter marks the locality check response message as valid even if it arrives after an original locality check time period since transmission of the locality check message, but before the end of an adjusted locality check time period. The adjusted locality check time period comprises said original locality check time period adjusted by delays in processing layers at the transmitter and wireless communication medium access delays in data communication between the wireless transmitter and the wireless receiver.

摘要： A system and method for efficiently communicating messages over a low-rate channel between multiple devices in a system for wireless communication of uncompressed video is disclosed. The method includes various control bits in a beacon control field of a beacon frame to improve the efficiency of the beacon processing, thereby reducing beacon processing time and size of the beacon frame itself. The transmitting device can use one or more of the various control bits to indicate whether there are changes in various MAC payload information fields. The receiving station can use one or more of the control bits to eliminate the need to parse one or more MAC payload information fields whose values have not changed from the previous beacon frame.

Pixels in an uncompressed video frame are grouped into groups of pixels for wireless transmission from a transmitter to a receiver, wherein the neighboring pixels in each group possess (have) high spatial correlation. Upon receiving the pixel groups, the receiving station reconstructs the video frame from the received pixel groups, wherein upon detecting an erroneous pixel in a group, information from one or more neighboring pixels in that pixel group are used in place of the erroneous pixel. Further, FEC encoding is utilized recovering bit-errors.

摘要： Reducing latencies for content protection in audio/video networks includes reserving a wireless channel for a time period to accommodate control message exchange for content protection in data communication between a wireless transmitter and wireless receiver over a wireless channel. The control message exchange includes wirelessly transmitting a control request message from the transmitter for content protection to the receiver, and transmitting a control response message from the receiver to the transmitter in reply. Reserving the wireless channel includes reserving the wireless channel for a time period that accommodates the control message exchange. The time period includes a single transmission opportunity period for communication on the wireless channel, to reduce latency for the control message exchange between the transmitter and receiver.

摘要： A method and system for device discovery in a wireless network is provided. The device discovery involves directionally transmitting a data unit from a transmitting station over a channel in different directions to emulate omni-directional transmission, receiving the data unit transmissions from different directions at a receiving station, determining the quality of the transmissions received from the different directions, and detecting location information for the transmitting station relative to the receiving station based on the highest quality transmission among the transmissions received from the different directions. Further, if a channel has sufficient bandwidth to satisfy direct link communication between two stations, then during a direct link set-up stage, the two stations conduct a probing message exchange using omni-direction transmission, and upon successful probing, obtain communication link status information and set proper communication configurations for the two stations based on the communication link status information.
