Talking about Mobile Phone Signal Blocking

Due to the development of communication technology, personal mobile communication has brought convenience to people's lives, and the impact of blocking mobile phone signals on similar occasions such as prisons and detention centers is becoming increasingly prominent. Once mobile phones are illegally brought into prison and put into practice, it will bring great harm to the management and security of prisons, detention centers, and other places. So establishing a truly effective mobile phone blocking system can provide strong technological support for prisons and detention centers. However, due to the current mixed market, many cheap mobile phone blockers are mainly suitable for general civilian use due to limitations such as performance indicators, reliability, and operating conditions. In large places such as prisons and detention centers, there may be certain problems, such as external interference, and some may even seriously affect public communication.
