About cell phone signal jammer in life
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.
