The wideband frequency jammer system is a professional modern communication signal jamming technology. Prison is a special environment, so the design requirements for the wideband frequency jammer system of the prison are higher and stricter. For the application of general conference system, the traffic volume is large, the location is fixed, and the blind area of communication shielding is nothing. In the prison, the number of people is dense and the activities are relatively concentrated. As long as the prisoners have a mobile phone, it is easy to search and find the blind spots of interference. Criminals do not deliberately search for blind spots. They will also search for missing blind spots through all kinds of text messages

(1) How to test the shielding effect

In prison, there should be no interference blind spots, repeated tests, professional detectors, and interference to equipment, radiation, and other systems; No omission

(2) Shielding outside the interference range

When the wideband frequency jammer equipment with good quality is completely shielded, it can not affect the communication of surrounding residents, so that the interference area is more accurate, and there is no shielding outside the shielding area.

(3) Hotline service

All excellent manufacturers have the awareness and team of providing high-quality after-sales service, will upgrade products regularly, return damaged machines to the factory, and provide a series of after-sales services to solve the difficult and miscellaneous problems in the use of users.

(4) Upgrade

The wideband frequency jammer systems are modular, which can be easily upgraded according to the changes of the surrounding base station facilities. This can save project investment and maximize the shielding effect with the least cost
