How do we install a 4G mobile phone jammer in prison to work normally. We must find the right path. As you know, the situation in prison is very complicated. Usually, there are guards, workshops and offices in the activity square, and criminals in prisons.

First of all, the installation procedure of the workshop is very practical and simple, because the workshop is always open. Just install a mobile phone jammer in every 30-meter open area on each floor. The height can not exceed three meters, only considering the length and scope of the workshop, the number, we can estimate the number of mobile phone signal jammers to be installed. However, it is difficult to install a cell phone jammer in the dormitory. Many concrete walls must increase interference to achieve the penetration of shielded signals. Therefore, we must install a jammer every fifteen meters from each floor to ensure that the shield is shielded. In addition, if blind spots are found during the installation process, we will choose to install many jammers on the outer wall of the dormitory. However, it is necessary to consider the previous water resistance and meet the number of dormitory to know the number of jammers.
