When customers buy cell phone jammer, they often think of the need to block cell phone signals in the conference room after completing the overall decoration of the conference room. After the decoration is completed, it is not difficult to choose a mobile phone signal jammer, but how to install it becomes a difficult problem. The first thing to consider is that the installation of the cell phone signal blocking device will affect the overall appearance of the conference room.
The problem of installing cell phone jammers in conference rooms affects the aesthetics not only when buying new jammers, but even some old cell phone jammers that have been installed before will face the need to upgrade to 5G shielding equipment when they are installed. Upgrading the iterative 5G shield, due to its larger appearance and more antennas, the original installation position is not enough.
Important entrance exams, qualifying exams or final exams require the installation of test room cell phone jammers to block electronic signals around the test room and prevent possible electronic fraud. So, how much area can the mobile phone signal blocker in the test room block? Can only one jammer in the examination room achieve the purpose of shielding? How many jammers should a school building use? First of all, we need to know: the mobile phone signal jammer in the examination room has a theoretical shielding range, which is about a radius of 0-20 meters. But note that this is a theoretical distance. The actual effect depends on the local signal strength, especially whether there is a signal base station nearby. If there is a signal base station within 200 meters, the shielding effect will be reduced.
