Will the full-screen segment signal blocker affect other devices when it is working?
In our daily life, full-screen segment signal blockers for cell phone are used in many areas, but how much do we know about this type of signal shielding equipment? We probably only know that full-screen segment signal blockers can affect mobile phone signals. Some exams use such equipment to prevent students from cheating with mobile phones. As for how the full-screen segment signal blockers currently in use work, many types of signal shielding equipment do not understand their principles. According to the appearance, these devices are full-screen segment signal blockers with internal antennas and full-screen segment signal blockers with external antennas. The full-screen segment signal blockers with external antennas are plastic shells, and the internal antennas are plastic shells. According to the area of use and the area of use, they can be divided into low-power full-band signal blockers and high-power full-band signal blockers. If used outdoors, the distance between floors is very far, and it is best to use a high-power full-screen segment signal blocker.
The working principle of the full-screen segment signal blocker is to pass the low-level working frequency of the wireless channel at a certain speed during operation, and high-end scanners. The scanning speed can also have an impact on the mobile phone receiving message signals. The mobile phone cannot detect the stable data transmitted from the base station, so that the mobile phone cannot establish a connection with the base station, and the effect of shielding the mobile phone signal is achieved. The mobile phone is reflected as network search, no signal, and no service system.

When the full-band signal blocker is activated, only the mobile phone has a shielding effect, and other electronic products have no harm. This is mainly because the electromagnetic induction signal emitted by the full-band signal blocker is completely within the national mobile phone working frequency band, which can only have a blocking effect on mobile phone communications. And this kind of signal is always in a relatively static state, which is not easy to affect any electronic products.
The full-band signal jammer for sale is not only used in school examination venues, but also in confidential meeting rooms, detention centers, military facilities, etc., especially in prisons, which must be equipped with full-band shielding to prevent criminals from contacting the outside world and not using mobile phones. When the full-band signal jammer is used in prison cells, it is recommended to use a small-power full-band signal jammer. When there is a shielding blind spot, a low-power full-band signal jammer can be used. In large areas, a high-power full-band signal jammer can be used.
