Abstract: A system and method for wireless communication over multi-rate channels are disclosed. One embodiment of the system includes source and destination devices that use first and second channels under a contention-based protocol. The first channel is directional with a first frequency and a first range. The second channel is omni-directional with a second frequency and a second range. The second frequency is lower than the first frequency, and the second range is greater than the first range. The source device may send the destination device a request for data transmission via the first channel over the second channel. The destination device may send the source device an approval for the data transmission over the second channel. The source device may further transmit an acknowledgment (ACK) of the approval over the second channel upon receiving the approval to prevent other devices in the system from contending for data transmission.

Abstract: 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.

Abstract: A method and system for wireless communication in a wireless network is provided. One implementation involves a requesting wireless station directionally transmitting a request to a coordinator for access to a communication channel; the request packet includes a field indicating the length of the desired reservation period; and upon successfully receiving the request from the wireless station, the coordinator reserving a channel time period for data transmission by the requesting wireless station, and at least pseudo-omni-directionally broadcasting a packet to all wireless stations in the network indicating the reservation. All other stations refrain from contending the channel during the reserved channel time period.
