摘要： A time-of-propagation distance-determining method involves sending a probe request from a handset to an AP and receiving a return ACK. The time it takes for the probe request to propagate to the AP, the turnaround time, and the time it takes the ACK to propagate back to the handset is measured on the handset. The turnaround time is subtracted from the measured time, and the result is used to make a distance determination. In order to reduce power consumption, the “lowest overall transmit energy” setting that will give acceptable reception of a probe request sent by the handset to the AP station is determined. The lowest overall transmit energy setting involves a bit rate setting and a transmit power setting. The lowest overall transmit energy setting is used to send probe requests when probe requests are sent from the handset in carrying out a time-of-propagation distance-determining transaction.
摘要翻译：传播时间距离确定方法包括从手机向AP发送探测请求并接收返回ACK。在手机上测量探测请求传播到AP所需的时间，周转时间以及ACK传播回手机所花费的时间。从测量时间中减去周转时间，结果用于进行距离确定。为了降低功耗，确定了能够接收手机向AP站发送的探测请求的最低总的发射能量设定。最低的总发射能量设置涉及比特率设置和发射功率设置。当进行传播时间距离确定交易时，从手机发送探测请求时，最低的总发射能量设置用于发送探测请求。
