Does the signal jammer affect other electronic equipment?
As far as we know about signal jammers, we probably know that shielding machines can interfere with mobile phone signals and can be used in the examination room to prevent candidates from cheating with mobile phones. We are not clear about how shielding machines work and their types. According to the appearance, the signal jammer can be divided into internal antenna and external antenna. The external antenna is metal shell, and the internal antenna is plastic shell. It can be divided into small power and large power according to the area of use and the area of use. If it is used outdoors, the floor distance is far, so it is recommended to use high-power signal jammer.
The working principle of the signal jammer is to scan from the low end frequency of the forward channel to the high end at a certain speed during the working process. This scanning speed can cause random interference in the message signal received by the mobile phone. The mobile phone cannot detect the normal data sent from the base station, so that the mobile phone can not be connected with the base station to shield the mobile phone signal. The mobile phone shows such phenomena as searching the network, no signal, no service system, etc.
Generally speaking, the frequency sent by the signal jammer interferes with the normal frequency of the mobile phone receiving base station, making it impossible for the mobile phone to connect with the base station, thus making calls, receiving and sending SMS messages and surfing the Internet. When the shield machine is turned on, although the mobile phone may have a full signal, there is no signal in the actual use process.
When the signal jammer is turned on, it only has a shielding effect on the mobile phone, and its electronic equipment has no impact. This is because the electromagnetic signal sent by the shielding machine is completely within the national collection working band, which will only block the mobile phone communication. And this signal is always in a relatively static state, which will not affect any electronic equipment.
The signal jammer is not only used in the school examination room, but also in the confidential meeting room, prison detention center, troops and other places. In particular, the prison must be equipped with a shielding machine. In order to prevent prisoners from contacting with the outside world, it is not allowed to use mobile phones. If it is used in prison, it is recommended to use large and small power signal jammers together. In case of shielding blind areas, small power shielding machines can be used, and large power shielding machines can be used in large areas.
