Abstract:
A method includes: separately performing, by a requester, time measurement with a plurality of responders, and calculating a location of the requester based on a measurement result. A measurement result obtained by the requester by performing time measurement with each responder includes time stamps t1, t2, t3, and t4, where t1 is a time when the responder sends a measurement frame, t2 is a time at which the requester receives the measurement frame, t3 is a time when the requester sends an acknowledgement frame in response to the measurement frame, and t4 is a time when the responder receives the acknowledgement frame. The acknowledgement frame is sent by the requester after waiting for a randomly generated short interframe spacing after receiving a last symbol of the measurement frame. The randomly generated short interframe spacing is randomly generated within a specified fluctuation range of a nominal short interframe spacing.

Claim (Index 7):
The method according to  claim 1 , wherein the plurality of responders comprise at least three responders that are not in one straight line, and an algorithm for calculating a planimetric location (x, y) of the requester is as follows: { ( x AP \ue89e \ue89e 1 - x ) 2 + ( y AP \ue89e \ue89e 1 - y ) 2 = C * [ ( t \ue89e \ue89e 4 AP \ue89e \ue89e 1 - t \ue89e \ue89e 1 AP \ue89e \ue89e 1 ) - ( t \ue89e \ue89e 3 AP \ue89e \ue89e 1 - t \ue89e \ue89e 2 AP \ue89e \ue89e 1 ) ] / 2 ( x AP \ue89e \ue89e 2 - x ) 2 + ( y AP \ue89e \ue89e 2 - y ) 2 = C * [ ( t \ue89e \ue89e 4 AP \ue89e \ue89e 2 - t \ue89e \ue89e 1 AP \ue89e \ue89e 2 ) - ( t \ue89e \ue89e 3 AP \ue89e \ue89e 2 - t \ue89e \ue89e 2 AP \ue89e \ue89e 2 ) ] / 2 ( x AP \ue89e \ue89e 3 - x ) 2 + ( y AP \ue89e \ue89e 3 - y ) 2 \ue89e = C * [ ( t \ue89e \ue89e 4 AP \ue89e \ue89e 3 - t \ue89e \ue89e 1 AP \ue89e \ue89e 3 ) - ( t \ue89e \ue89e 3 AP \ue89e \ue89e 3 - t \ue89e \ue89e 2 AP \ue89e \ue89e 3 ) ] / 2 , wherein\n (x APm , y APm ) is a known location of a responder APm; t 1 APM , t 2 APm , t 3 APm , and t 4 APm , are measurement results obtained by the requester by performing time measurement with the responder APm; APm\u03f5{AP 1 , AP 2 , AP 3 }; and m is a positive integer and m=1,2,3.
