LBS is a location based service and there are many ways to get location; gps trackers are just one way to get location. In addition, the location can also be acquired through a mobile base station acquisition method or a combination of a GPS tracker and a mobile base station.

　　But in most cases, GPS tracker is used to obtain location, this is because GPS tracker is free to obtain location, while mobile base station is charged to obtain location.

　　The GPS tracker cannot obtain location information in some special cases; the mobile base station can overcome this problem by obtaining the location.

　　Mobile base stations can determine your current location based on the distance between your phone and different base stations. But they are not necessarily related, gps tracker is just a way to get location data, it's free and simple. Other methods of obtaining location data are charged.

　　The shielding device shields the signal of the GPS tracker, and the LBS signal converted at this time can be positioned by the mobile base station.

　　Therefore, as long as the user's mobile phone is within the effective range of the mobile communication network, location positioning can be performed at any time without being affected by weather, tall buildings, and locations.
