Prison mobile phone signal shielding is an effective measure to combat prisoners' use of mobile phones for criminal activities. However, the implementation of this technology not only involves technical challenges, but also huge economic investment. This article will explore the implementation difficulties of prison signal shielding technology, its economic cost and future development trends.

　　1. Current status of signal shielding implementation

　　Since 2024, the Chilean government has begun to strengthen prison signal shielding measures nationwide. cell phone jammer The initial goal of this measure is to cover facilities that account for about 20% of the country's prisoners, including several large prisons near Pedro Monte and New Century Avenue in the metropolitan area.

　　2. Consideration of economic costs

　　However, the implementation of this measure is not easy. signal jammer The Chilean government's budget for shielding mobile phone signals in the Pedro Monte area alone has exceeded 3 billion pesos. There are 81 prisons in the country. If signal shielding is fully promoted, the budget demand will be as high as 600 billion pesos, equivalent to one-third of the total operating budget of the gendarmerie.

　　Faced with such high costs, the Chilean government had to prioritize 15 construction projects and planned to complete the signal shielding of these facilities between 2024 and 2025. Justice Minister Luis Cordero also admitted that the signal shielding system implemented in the past failed to achieve the expected results due to technical and management problems, which also provided important lessons for future improvements.

　　3. Innovation of technical solutions

　　Unlike the previous signal shielding system, the new system in the future will be more intelligent. The past system completely blocked the prison area, causing unnecessary interference to surrounding residents and staff. Now, the improved system can establish a specific shielding perimeter and accurately lock the devices used by prisoners without affecting residents outside the prison or internal staff.

　　The key to this technological innovation lies in its accuracy. The future signal shielding system will selectively interfere by identifying the signal of each device, rather than conducting a large-scale indiscriminate blockade. This improvement will not only better ensure the safety of the prison, but also reduce interference with other parts of society and improve the effectiveness of signal shielding.
