A system and method for a second wireless device to establish distance and location of a first device which is transmitting radio waves includes the first and second devices. Each second device includes two or more (N in number) receiving antennas. An angle between the directions in which adjacent receiving antennas receive the strongest signals is 360°/N. The second device obtains a received signal strength indicator (RSSI) of each receiving antenna receiving signals from the first device, and from the two strongest receiving antennas, calculation of an angle between the first device and one of the adjacent receiving antennas can be performed. The distance between the first device and the second device can also be calculated.
A positioning system comprising:
A positioning method, used for a first device to determine at least one second device, each of the second device comprising at least two receiving antennas, wherein a number of the at least two receiving antennas is defined as N, an angle between the directions in which adjacent two of the receiving antennas receive the strongest signals is 360°/N, the positioning method comprising:
