If you want to use a cell phone signal blocker to solve the problem of positioning your vehicle, first let’s discuss the working principle of the positioning device.
Positioning devices have many ways to achieve positioning
1. Positioning through operator base stations
There is usually a mobile phone sim card in the positioning device, which can receive base station signals and use data traffic. How to locate the base station? Generally, the triangulation method is used. (You can search on Baidu yourself)
2. Positioning via GPS
Everyone is familiar with this positioning method and will not go into details here.
3. Positioning via WiFi
WiFi positioning is similar to the positioning of operator base stations. Connecting to the network through WiFi is connected to the telecom operator network through a router. The operator will naturally know the approximate location of the router.
To sum up, if you want to use a signal jammer to solve the problem of vehicle location, you must not only interfere with the mobile phone signal, but also interfere with the GPS signal and WiFi signal. Only in this way can all the positioning signals of the positioning device be interfered with.
