How to choose network jammer in prison

How to choose network jammer in prison

  • 2022-05-12
In today's information age, with the rapid development of communication technology, mobile communication plays an important role in people's life, industrial and agricultural production and other fields. Mobile phones not only bring great convenience to people's life, but also produce some problems that can not be ignored. Due to the wide coverage of mobile communication network, the emergence of mobile phones on some occasions brings trouble to people and even potential safety hazards. Improper use of mobile phones has become a tool for disclosure in confidential places, posing a threat to the confidentiality of signals. Using mobile phones in prison will become a means of crime and have an impact on social stability. Therefore, in some places, we should be able to artificially destroy or limit this kind of network to avoid the harm brought by mobile network. Network jammer has been fully applied in this context.

In order to make the network jammer effectively interfere with the mobile phone signal, it must be ensured that the signal field strength sent by the jammer should be much greater than that of the mobile signal in the interference area. The signal field strength of each place is different. Therefore, the interference distance of the same jammer in different places is different, and the effective distance of interference will be different. The closer the base station is, the stronger the signal is, and the shorter the interference distance is; The farther away from the base station, the weaker the signal, the farther the interference distance. Therefore, before using the network jammer, the mobile phone signal strength at the interference site should be fully considered, and then the power, quantity and combination mode of the jammer should be determined according to the range of the interference area.

Generally, small power jammers are installed in indoor prisons; It is recommended to use high-power jammer outdoors. The two are combined to achieve full coverage of the whole prison.
