Signal disruptor for prisons

With the continuous development of mobile phones as a communication tool and the continuous improvement of popularization technology, especially the promotion and application of 5G technology, its negative impact on prisons, labor camps, detention centers, drug rehabilitation centers and other similar fields has become more and more prominent. Cell phones are expressly prohibited and not used as communication equipment in prisons, not only for prisoners but also for staff. The use of mobile phones in prisons will bring great harm to the development of prison management. Some prisoners call, send text messages, obtain information, and threaten witnesses through illegal smuggling, mobile phones, and even form gangs to escape from prison. For this reason, it is especially important to install signal jammers in prisons. There are also certain technical parameter requirements for the selection of mobile phone jammers.

At present, the main models of mobile phone jammers (signal jammers) recommended for use in prisons, detention centers and other supervision places mainly include: Shengma SMa-818B full-standard mobile phone signal jammer for low-power models, SMa-818K90 modular for medium-power models Signal jammer and SMa-818K200 high-power signal jammer.

At present, the power and channel of each base station are different, and the distance between each base station and the prison is different. No base station is needed within 200 meters or 300 meters of the prison area where the signal jammer system is installed. If there is a base station, consider the strength of the signal.

1. Influence from various building layouts in prisons. (The design of each prison is different, the size, surrounding buildings, terrain, and the signal strength of the surrounding base stations have a direct impact on the shielding effect of mobile phones)

2. Other influences (surrounding nature, geographical environment, magnetic field.)

Third, the selection and technical indicators of mobile phone jammer equipment. (The shielding range, power size, frequency band distribution, performance stability, and longevity of the mobile phone jammer all have certain requirements for the signal jammer, and which frequency bands are shielded by the signal jammer)
