The phones we use every day need a signal, so why use a wireless signal jammer? In fact, for those who can use mobile phones, of course, they hope that the stronger the mobile phone signal, the better. But for prisoners, secret units and other special places, it is of course necessary to effectively interfere with the mobile phone signal in order to make it safe and absolutely confidential.
Take the prison as an example. For the prisoners detained here, it is a necessary requirement to avoid contact with the outside world. Otherwise, how can they be rehabilitated with peace of mind? In addition, without a mobile phone signal, even if you have a mobile phone in your hand, you cannot communicate with them. External contact, which reduces the occurrence of inappropriate things such as escape.
However, there are still many staff in the prison. They need to communicate with the outside world from time to time, and they also need to receive instructions from the leaders of the superior units. Their external communication is very necessary, and this is also their right. The use of wireless wifi signal jammer here can effectively shield mobile phone signals in areas that should be shielded, such as prison cells, etc. In addition, signals in other office areas can also be received normally.
For some companies and units that need high confidentiality, it is also necessary to selectively block mobile phone signals, open some signal areas, and close some areas of signals, so as to prevent the occurrence of secret theft. The use of wireless signal jammer cannot be ignored, and shielding must be done to ensure the normal operation of the work.
