The signal blocker mainly intercepts radio waves from the base station and creates an unserviced shielded area. Like the concert hall, where quiet is needed, a gsm jammer is placed to shield the mobile phone's wireless signal.

In many places that need to be quiet, such as hospitals, libraries, churches, etc., irritating cell phone calls, mobile game noise, etc. can make people very unpleasant, in these places with GSM jammers, once activated, can interrupte all mobile signals in a certain area around, shielding nearby cell phone signals.

In banks or hospitals, telephones that ignore etiquette are very common and are very annoying. Using an gsm jammer can only interfere with cell phone signals without affecting other electronic devices, bank hospital machines, etc. Some powerful gsm blocker can also interfere with gps tracking devices, keep personal tracking privacy and location secret, long running time, significant functions, and low price. It is the easiest and most reliable way to stop radio waves.

With the advancement of society, more people will use drones, and drones will become more popular, which will make it more and more difficult to control drones. Some people do not obey the ethics and laws, use drones to sneak shots of other people's privacy, and even use remote control drones to steal other people's confidential information, resulting in information leakage and other irreparable major losses. At this time, there is drone jammer, It is very necessary.

When the signal blocker is turned on, it scans from the low-end frequency of the forward channel to the high-end at a certain speed. The scanning speed can form garbled interference in the message received by the mobile phone, so that the mobile phone cannot detect the normal data sent from the base station, and the mobile phone cannot establish a connection with the base station. Mobile phones are characterized by search networks, no signals on mobile phones, and no service systems.

The mobile phone itself is a eavesdropping device. The mobile phone in the call state will send all the surrounding sounds to the receiver. Even if the mobile phone is turned off, the surrounding sound can be obtained by the proprietary eavesdropping device as long as the battery is not removed. jammer devices are designed to block all signals in a particular area to avoid eavesdropping and help block signals such as GSM 3G 4G WIFI GPS.
