估计(异步)无线网络中的发送装置的位置的方法和系统
Abstract:
公开了一种用于定位移动装置的系统。在一个实施例中，系统包括具有处理器和接收机的移动装置，以及形成收发机装置的网络的至少三个收发机装置。移动装置和收发机可以由移动装置发送请求(REQ)包；由所述至少三个收发机装置接收REQ包；由接收REQ包的至少三个收发机装置中的第一收发机装置发送响应(RSP)包；以及由至少三个收发机装置中的至少一些接收REQ包和RSP包。针对接收REQ和RSP包两者的至少三个收发机装置，系统确定在接收REQ包和RSP包之间的到达时间差。系统可以基于所确定的到达时间差来确定移动装置的位置。
Abstract(English):

A system for locating a mobile device is disclosed. In one embodiment, the system includes a mobile device having a processor and a receiver, and at least three transceiver devices forming a network of transceiver devices. The mobile device and transceivers can transmit a request (REQ) packet by the mobile device; receive the REQ packet by the at least three transceiver devices; transmit, by a first one of the at least three transceiver devices receiving the REQ packet, a response (RSP) packet; and receive by at least some of the at least three transceiver devices the REQ and the RSP packet. The at least three transceiver devices that receive both the REQ and the RSP packet, the system determines a difference in arrival time between receiving the REQ packet and the RSP packet. The system can determine the location of the mobile device based on determined differences in arrival time.
