Abstract: An access point, a terminal, and a Wireless Fidelity indoor positioning method are provided. The method 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 t1; receiving, a second positioning signal sent by an ith second access point in n second access points, and recording a fourth moment ti4; sending, a response signal of the second positioning signal to the ith second access point, and recording a fifth moment ti5; receiving, a second moment ti2, a third moment ti3, and a sixth moment ti6 that are sent by the ith second access point; and determining, location coordinates of the terminal. In the embodiments of the present disclosure, clock synchronization is not required. In addition, terminal positioning accuracy is improved.
