This measurement technique uses a Received Signal Strength (RSS), a Signal Arrival Time (TOA), a Signal difference Of Arrival (TDOA), a Received Signal Phase (RSP), and the like.

(1) RSS: the attenuation of the transmitted signal strength is a function of the distance between the transmitter and the receiver. And according to the corresponding propagation signal path loss, converting the signal intensity into a distance for positioning, wherein the minimum of 3 reference points are required for the point to be positioned to participate in calculation. RSS based systems typically require adaptive mechanisms to reduce the effects of multipath fading and shadowing in indoor environments.

(2) TOA: the distance between the reference point and the point to be located is proportional to the propagation time of the signal. A time-of-arrival based system requires a minimum of 3 different measurement devices to accomplish two-dimensional positioning. TOA systems require time synchronization between all transmitters and receivers. If there are multiple reference points, a least squares algorithm is used to reduce the positioning error.

(3) TDOA: and converting the time difference into a distance difference according to different time of the signals transmitted by the to-be-positioned points reaching the plurality of measuring devices so as to determine the relative position of the to-be-positioned points. The TDOA method requires at least 3 measuring devices to participate in the measurement of the distance difference, requiring time synchronization between the measuring devices.

(4) RSP: and the distance is estimated by expressing the time delay by using the signal wavelength division. This approach requires the transmitter to be placed in a specific location and assumes that the transmitter transmits a perfectly sinusoidal signal. The position is estimated by measuring the phase value with the same algorithm as TOA, and the position can also be estimated by measuring the phase difference value with the same algorithm as TDOA.

(5) AOA: the position of the point to be positioned is determined by mainly utilizing a directional antenna or an array antenna to measure the angle information of the signal of the point to be positioned which linearly reaches a receiver.
