Will the full-screen segment signal jammer affect other devices when it is working
In our daily life, full-screen signal jammers are used in many areas, but how much do we know about this kind of equipment that can shield signals? Probably you should only know that the full-screen segment signal jammer can affect the mobile phone signal. Some exams use this type of device to prevent students from cheating with their mobile phones. Regarding how the full-screen segment signal jammer currently in use works, there are many types of signal shielding devices. Understand its principle. According to the appearance of this kind of equipment, they are the full-screen segment signal jammer with built-in antenna and the full-screen segment signal jammer with external antenna. The full-screen segment signal jammer with external antenna is a plastic shell, and the built-in antenna is a plastic shell. The area and area of use can be divided into low-power full-band signal jammers and high-power full-band signal jammers. If it is used outdoors, the distance between floors is very far. It is best to use high-power full-screen signal jammers.
The working principle of the full-screen segment signal jammer is to go to the low-level working frequency of the wireless channel at a certain speed during the operation process, and the high-end scanner. The scanning speed can also have an impact on the mobile phone receiving the message format signal. The mobile phone cannot detect the stable data information transmitted from the base station, so that the mobile phone cannot establish a connection with the base station, so as to achieve the effect of shielding the mobile phone signal. The mobile phone is reflected as a network Search, no signal, no service management system phenomenon.

For network search, no signal, no service management system phenomenon.
When the full-screen segment signal jammer is activated, only the mobile phone has a shielding effect, and other electronic products have no harm. The main reason is that the electromagnetic induction signal sent by the full-screen segment signal jammer is completely within the working frequency band of mobile phones stipulated by the state, which can only block mobile phone communication. And this kind of signal is always in a relatively static state, and it is not easy to affect any electronic products.
The full-screen signal jammer is not only used in the college examination room, but also can be used in the confidential meeting room, the detention center, the army, etc., especially the cell must be equipped with full-band shielding, in order to prevent criminals from contacting the outside world. No, with a mobile phone. If the full-screen signal jammer is used in a prison cell, it is recommended to cooperate with the size output power full-band jammer. When there is a shielding blind spot, you can use a low-power full-band signal screen. In a large-scale area, you can use a high-power one. Full-band signal jammer.
