Access point, terminal, and wireless fidelity WIFI indoor positioning method

摘要

Embodiments of the present invention provide an access point, a terminal, and a Wireless Fidelity WiFi indoor positioning method. The WiFi indoor positioning method in the present invention includes: receiving, by a first access point, a first positioning signal sent by a terminal, and recording a moment for receiving the first positioning signal as a first moment t 1 ; receiving, by the first access point, a second positioning signal sent by an i th second access point in n second access points, and recording a fourth moment t i4 ; sending, by the first access point, a response signal of the second positioning signal to the i th second access point, and recording a fifth moment t i5 ; receiving, by the first access point, a second moment t i2 , a third moment t i3 , and a sixth moment t i6 that are sent by the i th second access point; and determining, by the first access point, location coordinates of the terminal according to t 1 , t i2 , t i3 , t i4 , t i5 , and t i6 . In the embodiments of the present invention, clock synchronization is not required. In addition, a delay of processing a received signal by an access point can be obtained accurately, and terminal positioning accuracy is improved.
