In the whole local network, covering some local networks and providing roaming network services, in addition to considering the coverage, the network structure and dynamic environmental factors may also make it impossible for telecom operators to roam in the local network. Accuracy, mobile phone positioning should provide different accurate services according to the different service needs of users, and can provide users with accurate choices. For example, the probability of positioning accuracy within 50 meters is 67%, and the probability of positioning accuracy within 150 meters is 90%. On the one hand, the positioning accuracy is related to the positioning technology used, on the other hand, it depends on the external environment of providing services, including the radio transmission environment, the density and geographical location of the base station, the equipment for positioning and so on.
