We use mobile phones to make phone calls every day, video chat with distant friends, communication at leisure time. The mobile phone has gradually replaced the real friends and become our companion to pass the time. It can be said that the emergence of mobile phones has brought great convenience and funs to our lives, but also brought a lot of troubles. For example, if the phone call in the restaurant is very loud. the mobile phone of the colleague suddenly rings during the meeting, which will affect our work and even life.
But why can a mobile phone allow us to communicate face to face even if we are far away from our friends? The reason the mobile phone can talk is to receive the signal transmitted by the tower. We will find that the closer the signal is to the signal tower, the stronger the signal received by the mobile phone, the faster the network speed, if the distance is too far, it would be impossible to connect to the network. So how do we sometimes mask the signal?
The wifi jammer transmits the same radio wave through it to achieve the purpose of suppressing the other party's signal. The application of wifi jammers is very extensive. Some branches, government departments and university examination rooms will install some high-power wifi jammers to achieve the purpose of shielding mobile phone signals to prevent information leakage and cheating in exams.
In some military fields, the use of wifi jammers is more common, especially in prisons. Prisons can use mobile phone jammers to cover cell phone signals around the prison to prevent prisoners from gaining access to the outside world through some invisible means and conducting illegal transactions.
