摘要： A system and method for discovering and tracking communication directions is disclosed herein. In one embodiment, communication directions for two devices with asymmetric antenna systems are discovered. In one embodiment, a contention access period (CAP) is partitioned into an association CAP and a regular CAP, either of which may be further partitioned into sub-CAPs corresponding to different reception directions. In one embodiment, an association request command is transmitted by a device at different association sub-CAPs to train a transmission direction of the device. In one embodiment, further training is performed to find the best communication directions, as collisions may occur when association request commands are transmitted at different association sub-CAPs.

摘要： A system and method for providing a proximity control between devices in a wireless network is disclosed. A test message for a Round Trip Time (RTT) test is transmitted from a first device to a second device via a modified reservation function, wherein the modified reservation function is based on a distributed media access control scheme. A response message for the RTT test is received from the second device via the modified reservation function. A distance between the first device and the second device is computed based on a round trip time delay between the test message and the response message.

摘要： Method and system for transmission of uncompressed video information from a sender to a receiver over wireless channels are disclosed. For example, according to one embodiment, when channel conditions (e.g., noise or interference) worsens, one or more least significant bits (LSB) of pixel data are not transmitted to save bandwidth for more efficient transmission. Furthermore, the remaining one or more of the most significant bits (MSB) of the pixel data are transmitted with coding and/or modulation schemes that provides extra error protection, relative to what is needed in regular channel conditions.
