Upon receiving a beacon, a terminal B sends a RTS control message to a terminal A before sending a registration request message to the terminal A. Upon receiving the RTS control message, the terminal A sends a CTS control message. The terminal B measures the time from when the RTS control message is sent to when the CTS control message is received so as to calculate the distance with the terminal A. If the distance with the terminal A is within a predetermined distance X1, the terminal B sends a registration request message to the terminal A. Similarly, the terminal A measures the distance with the terminal B, and sends a registration request acknowledgement message to the terminal B when the distance with the terminal B is within a predetermined distance X2.

A wireless communication network that forms an ad-hoc network without the arrangement of a controlling station sets a period that a communication apparatus can utilize with priority and performs isochronous communication in the period as required. When isochronous communication has not been performed or after isochronous communication has finished in the priority utilization period, other communication apparatuses perform arbitrary communication. When another communication is performed in a communication apparatus's own priority utilization period, the start of isochronous communication is temporarily delayed. In an ad-hoc communication environment, data having a real-time characteristic, such as AV content, can be efficiently transmitted through the isochronous communication.

摘要:
A system and method for performing ranging and positioning as follows by using the procedure for packet transmission and reception between a sender and a recipient. A first radio set transmits packets to a second radio set as a recipient. The second radio set returns the packets without fail after the lapse of time (from the detection of packets) which corresponds to an integral multiple of a prescribed unit time. The first radio set counts, by using its counter, the time which has elapsed from its transmission of packets to its detection of packets from the second radio set. The remainder of the thus counted time after subtraction of the time taken by the second radio set from packet detection to packet return and the processing time of the first radio set itself is converted into the distance of propagation between the first radio set and the second radio set as a recipient.
