what other methods can be used to shield mobile phone signals in addition to electronic jammers?

  • 2022-04-04


There are usually two ways to shield mobile phone signals:

The first way is to use signal interference (shielding), that is, the most commonly used electronic jammer. It applies interference signal to each working frequency band of mobile phone signal, so as to achieve the purpose of shielding mobile phone signal.

The second is to use shielding materials to shield the place where mobile phone signals need to be shielded as a whole, which is equivalent to adding a shielding cover to the place to isolate the wireless signals inside and outside the place. This can also meet the requirements of shielding mobile phone signals. Such shielding materials include: shielding bricks, shielding plates, shielding curtains, shielding doors and so on.

So what are the obvious differences, advantages and disadvantages between the two ways of shielding mobile phone signals?

Method of using electronic jammer: the investment cost is very low and the effect is fast. You can decide when to start the electronic jammer according to the use requirements to achieve the purpose of shielding mobile phone signals. There are no restrictions on the application environment. It can be used indoors and outdoors. Moreover, the shielding range can be determined according to the transmission power of the electronic jammer. The disadvantage is to pay attention to the maintenance of the equipment.

Method of using shielding materials: the investment cost is very high, so it is necessary to plan the place of use in advance, and install the shielding materials in place in advance during basic decoration. At the same time, it also needs to be installed very carefully, and no blank area can be left, otherwise it is easy to cause signal leakage, which will lead to the waste of previous efforts in shielding mobile phone signals. Once completed, the place of use will permanently maintain the state of shielding mobile phone signals.

Finally, it should be noted that the use of shielding materials is almost limited to indoor use. For the outdoor environment, we can only adopt the way of electronic jammer.
