In recent years, prisons across India have frequently reported cases of prisoners communicating with the outside world through mobile phones, and Brier Model Prison is the "hardest hit area" of such problems. signal jammerAlthough the prison has tried to block signals by installing jammers for many years, the existing 2G jammers have been unable to cope with the more advanced smartphones in the hands of prisoners. cell phone jammer To solve this problem, Brier Prison plans to introduce portable jammers to further block 4G and 5G signals to prevent prisoners from continuing their illegal activities through modern communication technology.GPS jammer

Outdated 2G jammers fail, prison communication management needs to be upgraded

　　Sources inside Brier Model Prison revealed that the 2G signal jammers installed in 2008 are still in use in the prison. Wifi jammer These jammers once played an important role in blocking old mobile phone communications, but with the popularization of 4G and 5G networks, the functions of mobile phones in the hands of prisoners have long been greatly improved. According to prison management, in the 2022 raid alone, the police seized 10 smartphones, multiple Bluetooth devices and chargers from prisoners, showing that the existing jamming system can no longer effectively prevent illegal communications.

　　At present, the new portable jammer solution proposed by Bharat Electronics Limited (BEL) has attracted great attention from prison management. Compared with traditional fixed jammers, these new devices have greater flexibility and adaptability, and can adjust the signal shielding range according to actual needs to ensure the effectiveness of communication management.

　　Advantages and technological innovation of modern jammers

　　The new jammer design idea is portable, intelligent and efficient. The portable jammer can not only adjust its position at any time to deal with the "signal dead spots" that may appear in the prison, but also accurately shield specific frequency bands, such as 4G, 5G networks and WiFi signals. In addition, the new device will also integrate remote control and monitoring functions, and prison managers can monitor signal interference in real time through special software to ensure that the interference effect is as expected.
