As an essential tool in the examination room, the signal blocker in the examination room escorts the security of the examination information. However, if we do not use the device correctly, it may lead to poor shielding effect, or even an accident in the examination room. The following are the key points about the use of signal jammers in the examination room:
1. The effective shielding range of the signal shielding device in the examination room will be different in different use sites. This is closely related to the signal field strength at the scene. Different brands of mobile phones have different shielding effects on the same site. The distance, orientation, and presence of obstacles relative to the base station, the wall material of the on-site building, the installation of the signal shielding device in the examination room, etc., may affect the shielding range;
2. If the surface temperature of the signal shield in the examination room rises rapidly after working for a long time, don't worry about it, this is a normal phenomenon. During use, in order to avoid possible interference to some electronic devices, keep a distance from other common electronic devices as much as possible.
3. When installing the signal jammer in the test room, try to install it in a position where there are no obstacles between the target shielding area and the installation height of 1.8m to 2.5m. Keep the jammer vertically upward during installation.
Topsignaljammer Technology Co., Ltd. specializes in the shielding industry for more than ten years, and can effectively shield 2G, 3G, 4G, 5G and other signals of China Mobile, China Unicom and Telecom.
In this way, the effect of installing a mobile phone signal jammer is doubled:
In our work every day, customers often ask us what kind of environment we can assemble the best mobile phone signal jammer. Why can’t the mobile phone signal jammer on some clothes work, or the effect is relatively poor? ?In fact, this is ultimately related to the surrounding environment when you use the mobile phone signal jammer. So under what circumstances is it less effective to install a mobile phone signal jammer?
