The game between technology and communication problems in prison Although mobile phone signal jammers have been installed in Puzhal Prison, prisoners still manage to break through the barriers and use mobile phones illegally. cell phone jammerThis phenomenon not only reflects the technical difficulties in modern prison management, but also reveals the means by which prisoners cleverly circumvent control. The case of Puzhal Prison shows that relying solely on signal jammers is not enough to eliminate illegal communications, and prison management is facing new challenges.GPS jammer

　　The hidden proliferation of mobile phones in prisons In the latest raid, the Puzhal Prison Administration seized a total of 9 mobile phones and related accessories in multiple areas. Wifi jammerThese devices were not only hidden in the prisoners' personal belongings, but also appeared in key areas such as the highly guarded Building 1. These seized items show that although the signal jammer was installed two months ago, it failed to completely prevent prisoners from communicating with the outside world. According to statistics, there were 72 cases of illegal use of mobile phones throughout last year, and this year has not yet ended. The number of such cases is close to last year's level, showing that the effectiveness of jammers is limited.

　　Prisoners' "technical" breakthroughs: skills for hiding and avoiding interference Prison officials revealed that prisoners are very sophisticated in hiding their mobile phones, and their methods are constantly upgrading. For example, they will hide their mobile phones in toilet drains, soles of shoes, or even the heels of slippers to avoid routine searches. Prisoners use personal items such as tableware, clothing, or daily cleaning supplies to cleverly disguise their mobile phones, making them difficult to detect. In addition, some experienced repeat offenders have even found "signal blind spots" in prisons, where the signal coverage of jammers is weak, allowing them to use their mobile phones unimpeded.

　　Prison guards "cooperate": supervision loopholes of internal personnel In addition to prisoners trying to find their own way, some prison guards accept bribes to provide prisoners with mobile phones, chargers and other equipment, further exacerbating the difficulty of management. Especially after the jammer is installed, prisoners rely more on the help of internal personnel to obtain mobile phone signals. Once prisoners obtain communication tools, they can continue to plan criminal activities and direct the actions of their accomplices outside. This situation not only threatens the safety of prisons, but also poses a hidden danger to social security.
