With the development of modern technology, mobile phones have become an item that people carry along with their voices. For the fairness of examinations, all-band jammers are installed in school examination rooms. Wherever they are installed, the shielding effect is stronger.
1. The low-power full-band signal blocker is recommended to be placed on a normal teacher's podium or desk. For fixed installation, it is recommended to have a height of about 180cm-220cm above the ground. It is better if the angle can be tilted forward.
2. Is there any obstacle between the jammer and the mobile phone, or whether there is a wall or other things between the shielded area and the jammer. During the transmission process, the shielding signal emitted by the shielding device will be attenuated if it encounters obstacles or penetrates the wall, which will affect the shielding effect.
3. The distance between the jammer and the communication base station, the farther the full-band jammer application environment is from the base station, the better the shielding effect of the jammer. 】
4. The scope of on-site shielding, if the area in the classroom is small, you can choose a low-power full-band jammer, and if you need to shield a large range, you can choose a high-power jammer.
5. Do not stack other items in front of the equipment when the equipment is working, and do not disassemble the machine to remove the antenna inside, which will affect the damage of the full-band jammer.
6. The shielding device is installed outdoors, and attention should be paid to waterproof, dustproof and insect-proof. Keep away from corrosive gases and liquids, the internal aging of the machine will affect or damage the internal components and affect the life of the machine.
