With the development of the communication industry, especially the application of 5G technology, communication technology has brought great improvement to people's lives, and its negative impact on security occasions such as prisons, detention centers, college entrance examinations has become increasingly obvious. In the past two years, college students used 5G mobile phones to cheat, which had a strong warning effect on the monitoring system. If criminals in prisons use mobile phones, the management and security of prisons and detention centers will be seriously affected.

How to block cell phone communication signals in prison? Here we must mention the 5G mobile phone signal jammer in the prison. Establish a truly effective prison cell phone protection system to provide a strong security guarantee for prisons and detention centers.

Technically, the essence of the mobile phone signal jammer is electronic countermeasure or co frequency interference, that is, when the mobile phone uses the band signal sent by the antenna to receive the downlink signal, it cannot identify and receive the network due to the error code, and the mobile phone does not display the network status. This can achieve the effect of signal shielding. In fact, wireless signal shielding is a project with high technical requirements. This cannot be solved simply by purchasing and installing signal shielding equipment. In order to establish a complete prison cell phone signal shielding system, on-site measurement, power calculation, construction scheme and equipment commissioning must be carried out.

Buy hundreds of prison cell phone jammers. In a complex environment, when it is necessary to use a signal jammer for wireless signal shielding, from a professional perspective, high gain antennas should be used for large-scale shielding, and small indoor antennas should be used for further optimization to protect some corner blind areas. The professionals have configured and debugged the local environment for many times to achieve tight shielding inside the prison and perfect shielding outside the prison without interference.
