How far can a telephone jammer shield?
The shielding distance of the telephone
jammer depends not only on the efficiency of the equipment itself, but also on
the actual site terrain, nearby base stations, building materials, and whether
there are unnecessary obstructions. For example, when the signal passes through
reinforced concrete, glass and wood, the degree of signal attenuation is
different, which will more or less have some impact.
In today's communication era, there are
more and more places where telephone jammers are used, such as examination
halls, gas stations, meeting rooms and other places. Shielding equipment is
used in these places to shield the mobile phone signal, so that the mobile
phone does not need to be turned off, and also avoids some unnecessary trouble.
The working mode of the telephone
jammer is that the frequency band of the transmitted jamming signal is used to
shield the signal band of the mobile phone receiving base station. In general,
the power of the transmitting frequency band of the shielding device is greater
than the power of the received signal of the mobile phone, so that the mobile
phone signal can be shielded. On the contrary, it will not work and will not
affect the use of mobile phones. Therefore, more attention should be paid to
these problems when using these shielding devices. Of course, the effective
coverage area of the telephone jammer is not supported by more accurate data,
and there are many factors that can affect it. Before choosing it, we should
test the interference effect of the device more through the mobile phone,
assess the field environment, and then decide whether it is necessary.
