1.3 Demand analysis
1.3.1 Performance requirements of wireless positioning system:
To achieve mobile positioning, that is, to locate the mobile personnel in the mall, it is required to minimize the positioning delay to ensure the real-time performance of the system.
The general positioning accuracy is required to be controlled within the range of 10-20 meters, and the accuracy of individual areas can reach 3-5 meters.
It can be interconnected with the shopping mall APP system platform to achieve coordination between multiple systems.
Method to realize:
Smartphones can be positioned by installing or not installing software, the difference is as follows:
No software installation: AP needs to use U-band or the AP locator specified by U-band to achieve positioning.
Install software: AP can realize positioning function by using U-band or ordinary AP.
