Example Embodiment
[0060] Hereinafter, in conjunction with the accompanying drawings, a preferred specific embodiment is described in detail to further illustrate the present invention.
[0061] Such as figure 1 As shown, an indoor positioning system is used to locate a target 100. The target 100 can send wireless base station signals and have Internet access, such as 2G, 3G or 4G. Preferably, the target is an intelligent Handheld devices (Mobile Devices) such as iOS or Android mobile phones, the indoor positioning system includes: a number of receivers 200, each receiver 200 includes an omnidirectional antenna and a number of directional antennas, respectively used to scan the target 100. Preferably, each receiver 200 includes an omnidirectional antenna and four directional antennas. The four directional antennas are named Ant1, Ant2, Ant3, and Ant4 respectively, that is, the receiver 200 can Receive 5 sets of wireless base station signal values (RSSI values) at the same time; the processor 300 ...
