Rich actual operation: Upin Technology has hundreds of successful WiFi positioning cases at home and abroad, including exhibition halls, office buildings, factories, ports, prisons, coal mines and other industries in various complex environments
2.2.1 Comparison of AP scan mode and terminal scan mode
The real-time positioning system of Youpin Technology supports both AP active scanning mode and terminal scanning mode. The comparison of these two modes is as follows:
AP active scanning mode terminal active scanning mode
There is almost no impact on WiFi network communication. Competing with other WiFi communication devices for bandwidth, which has a great impact
Number of Positioning A single AP locates more than 200 terminals per second, a single AP locates 30-50 within a few seconds
Positioning response time is less than 1 second 3-5 seconds
Positioning accuracy APs do not interfere with each other in active scanning mode, so the AP deployment density can be very high, and the positioning accuracy can reach 1 meter. APs will interfere with each other. The ideal positioning accuracy is 3-5 meters. APs are actually deployed The distance between 20-30 meters is generally not ideal
Power consumption terminal equipment needs to be connected, only a single transmission of the signal is enough, so it is more power-saving, it must be connected to the WiFi network, it needs to be transmitted multiple times, so it is more power-consuming
WiFi terminal device types support any WiFi terminal device, including Apple’s iOS and Windows Mobile devices, only support the ANDROID system
WiFi terminal software requires that the WiFi terminal device does not need to install an APP, and it can also actively locate the WiFi device. The terminal device must be installed with an APP before it can be located.
AP support requires APs to support active scanning mode. Through cooperation with mainstream manufacturers at home and abroad, general APs support any AP of UB Technology’s positioning engine, and there is no requirement
According to comparison, the AP active scanning mode is superior to the terminal active scanning mode in other aspects except that it has requirements for the AP. Moreover, we have also solved AP requirements by cooperating with mainstream manufacturers at home and abroad. This project will adopt AP active scanning mode.

2.4.3 Market positioning
The mall covers a wireless local area network. After the customer’s WiFi smart terminal is connected to the mall’s WiFi, it periodically sends out signals. After receiving the signal, the wireless local area network access point (AP) transmits the signal to the positioning server. The location server judges the location of the person according to the strength of the signal or the time difference of signal arrival, and displays the specific location on the electronic map.
Positioning-based wireless local area networks are different from general communication networks and require that at any location, more than 3 AP signals can be received. The positioning algorithm adopts the positioning method based on RF fingerprint recognition (FINGERPRINTING). Set multiple sampling points in the positioning area, and place the positioning terminal at one sampling point. The scene planning tool can record the characteristics of the signals emitted by the positioning terminal, and establish signal patterns based on these characteristics and signals at different locations to indicate the position of the positioning terminal. After the database is established using the signal pattern and the corresponding position information, the positioning system can calculate the position based on the signal characteristics collected in real time.
