In the era of science and technology, mobile phone after one generation of upgrades, also more and more perfect on the function, tend to be more intelligent, thus appeared the smartphone popularization, more and more people can't reasonable use of mobile phones, created a series of problems related to mobile phone. In this case, GSM, as a basic communication signal frequency band, is subject to interference. The GSM jammer in the market is a professional equipment to interfere with mobile communication.

The cell phone interrupter interrupts any type of wireless communication related to the cell phone. Cellular telephones operate by communicating with their service networks via cellular towers or base stations. The honeycomb tower divides the city into small areas or communities. When a cell phone user drives into the street, the signal is sent from the tower to the tower. In fact, the technologies behind mobile phone signal interference device is very simple, similar to radio waves, disrupt the mobile phone need to signal frequency, the RF signal retention radio interference in the frequency range of mobile phone set aside, the interference signal, leading to the phone's screen shows "can't use network" or "weak signals. As a result, all mobile phones within the effective range of the scrambler are silent. In fact, the jamming device blocks reception from the phone and is difficult to detect.

While the use of mobile jammers by individuals and local businesses remains controversial, there is a global consensus around the wisdom of fuzzy cell phone jails. All these problems caused by cell phones can be solved by cell phone jammers. I don't think anyone would refuse such a good device to help solve their problems, reasons - there is no reason not to confiscate the prison guards have a walkie-talkie on foot, not influenced by the intruder (they should not have even phone), so that communication is not without interruption. The stuck airspace can be designed and adjusted so as not to affect areas outside the prison. If an emergency is declared and the emergency services must have access to prison, the protocol allows for disabling the scrambler. Cell phone jammers in prisons are designed to interrupt unauthorized cell phone communications in prisons. The device helps control communications between prison criminals. This form of interference is common in court environments and military installations. The mechanism of this type of spoiler is more complex than that of an ordinary mobile phone spoiler because it can detect callers automatically or manually and prevent unauthorized calls.
