We use our mobile phones every day to find signals, why do we need cell phone signal blockers? In fact, there are two aspects of this fact. For people who can use mobile phones, of course they hope that the mobile phone signal is as strong as possible. However, for special places such as prisoners and confidential units, it is of course necessary to effectively interfere with mobile phone signals in order to achieve safety and absolute confidentiality.
Take the prison as an example. For the prisoners held here, signal jammer is a must to maintain contact with the outside world. Otherwise, how can they accept the reform with peace of mind? In addition, there is no mobile phone signal. Even if you have a mobile phone in your hand, you cannot communicate with the outside world. Contact reduces the occurrence of inappropriate things such as escape.
However, there are still many staff in prisons who need to have normal contact with the outside world and accept the leadership of higher-level units. Their external contacts are necessary and this is also their right. The mobile phone signal blocking system here can effectively and targetedly block mobile phone signals in areas that should be blocked, such as prison cells, etc. Otherwise, the signals in other places can be normal.
For some enterprises and institutions that require a high degree of confidentiality, it is also necessary to selectively block mobile phone signals to open some signal areas and close the signals in some areas, so as to prevent the occurrence of secret theft incidents. Although the use of mobile phone signal shielding systems is a small-scale market demand, this market cannot be ignored. Shielding work must be done well to ensure the normal operation of this institution.
