Mobile positioning principle-gps/glonass/Beidou + WIFI + Base Station

, deduced the latitude and longitude of unknown WiFi. If there is no known wifi, and the phone happens to be on the GPS, you can also complete the data collection. The user unknowingly collects all the data for the map company. As you can imagine, this amount of data is very large.Base Station positioning:The number of base stations is far less than WiFi, and the base station has public location data, so the acquisition is relatively simple.Precision for multiple positioning pathways:Satellite P

Mobile IP strategy of GPRS

Absrtact: This paper discusses a method of implementing Mobilt IP support on GPRS, and simply analyzes the evolution strategy. First, the introduction The IP protocol does not effectively support moving across subnets because the IP address is associated with a particular network segment, and the movement of the terminal destroys the association so that communication does not work properly. The mobile IP and ETSI proposed by IETF are all designed to solve the problem of the frequent terminal m
