The GPS signal jammer mainly releases radio interference that can disable the GPS locator within the specified electromagnetic waveband and create the same electromagnetic environment as the device to block the signal. Currently, it is mainly used to shield GPS satellite signals so that no data can be uploaded to the platform, so that the device cannot be used normally offline.

In theory, the GPS signal is shielded (the current jammer can be shielded along with the LBS signal) and the car dealer cannot find the vehicle information. The prerequisite, of course, is that the GPS jammer must be constantly powered or that the GPS tracking device is removed, otherwise the car dealer can still position it.

The cell phone signal jammer scans from the lower frequency of the forward channel to the upper end at a certain speed during operation. This scanning speed may cause garbled interference with the message signal received from the cellular phone, and the cellular phone cannot recognize the normal data sent by the base station, so that the cellular phone cannot connect to the base station. The mobile phone manifests itself as the phenomenon of searching the network, the mobile phone with no signal, no service system, etc.

To prevent students from using cell phones, schools usually use jammers to cheat. For security and management reasons, prisons can also use high-performance jammers to prohibit prisoners from communicating with the outside world and to reduce threats to the prison. When used correctly, mobile wireless jammer are definitely an advantage. Regardless of the environment, those who keep talking on the phone may be able to remain silent. Interference transmits high-power signals at the same frequency as the cell phone, causing the two signals to collide and cancel each other out. This is the basic working principle of any jammer. Simple devices only block one set of frequencies. High-end devices can block all frequencies at the same time. Cell phones are full duplex devices, meaning they use two different frequencies. One listens, the other speaks. Some basic jammers can only block one of these frequencies. Advanced jammers not only interfere with all cell phone signals, but also many other signals. It also has a unique frequency switch that can be selected based on your needs.
