Small radius jammer is an inevitable product of the security industry

The difficulty of prison management is also impacted by high-tech products. As for the ban on mobile phones, I have been checking it and I have not been clear. The current smart phones do cause problems for prison management. This time, a prison in Guangdong Province installed an illegal cell phone signal jammer detection system, making the problem easier.

The location of the illegal mobile phone detection system is very accurate, and the accurate detection of mobile phone signals can play a very good role in investigating and punishing illegal mobile phone use. After the introduction of mobile phone jammers, the prison conducted a comprehensive survey and detected more than 30 mobile phones at one time, which surprised the managers.

Thieves can obtain illegal small radius cell phone jammer. Their sizes range from small portable devices to large briefcases. They transmit signals at mobile frequencies. This prevents the GPS tracking device in the vehicle from sending and receiving messages. The signals transmitted by these illegal devices form bubbles around the vehicle, very effectively "silent" tracking the device, and no one knows what's going on. This incident happened recently in Congress. Large jammers have been deployed throughout the US Congress, which can effectively block all cell phone signals in the House of Representatives. He can track equipment with three main requirements for anti-interference. First, the mobile phone signal jammer device must be able to detect signal interference. Next, he needs to send an urgent message to tell someone "I'm trapped". The third and most important thing is that you need to be able to send this emergency message at a frequency different from the blocking frequency. Beware of scammers-if there are no other unhindered frequencies, the solution will fail.
