How far can a cell phone signal jammer be shielded? This depends not only on the efficiency of the equipment itself, but also on the terrain of the actual site, nearby base stations, the material of buildings and whether there are unnecessary obstructions. For example, if the signal passes through reinforced concrete, glass and wood respectively, the attenuation degree of the signal is different, which will have some influence more or less.

In today's communication era, more and more places use cell phone signal jammers, such as examination rooms, gas stations, conference rooms and other places. In these places, shielding equipment is used to shield the mobile phone signal, so that the mobile phone does not need to be turned off and some unnecessary troubles are avoided.

The transmitted interference signal frequency band is used to shield the signal frequency band of the mobile phone receiving base station, which is the working mode of the cell phone signal jammer. In general, the power of the transmitting frequency band of the shielding equipment is greater than the power of the received signal of the mobile phone, so as to realize the effect that the mobile phone signal is shielded. On the contrary, it will not work, let alone affect the use of mobile phones. Therefore, when using these shielding equipment, we should pay more attention to this problem.

Of course, the effective coverage area of cell phone signal jammer does not have much accurate data to support, and there are many factors that can affect it. Before choosing it, we still need to test the interference effect of the device through the mobile phone, assess the field environment, and then decide whether to use it.
