How to choose the point of the full-band signal jammer

With the development of modern technology, mobile phones have become a necessity for people to carry with them. Examination is an important evaluation tool. In order to ensure fairness, full-band signal jammers are installed in the school examination room. However, when installing a full-band signal jammer, how to choose a suitable point is very critical. This article will introduce how to select the point of the full-band signal jammer to ensure that its shielding effect is stronger.

1. Point selection

The low-power full-band signal jammer is recommended to be placed on a normal teacher's podium or desk. The height of fixed installation is recommended to be about 180cm-220cm from the ground. It is better if the angle can be tilted forward.

2. Obstacle occlusion

Is there any obstacle between the jammer and the mobile phone, or is there a wall or other things between the shielded area and the jammer? During the transmission process, the shielding signal emitted by the jammer will attenuate when encountering obstacles or penetrating through walls, which will affect the shielding effect.

3. Distance from the base station

The distance between the jammer and the communication base station will also affect the shielding effect. The farther the application environment of the full-band signal jammer is from the base station, the better the shielding effect of the jammer will be.

4. Range size

The extent of field shielding should also be considered. If the area in the classroom is not large, you can choose a low-power full-band signal jammer. If the shielding range is large, a high-power shielding device should be selected.

5. Equipment Protection

When using, please be careful not to pile up other items in front of the device, and do not disassemble the machine to remove the antenna inside, so as not to affect the damage of the full-band signal jammer.

6. Installation environment

If the jammer is installed outdoors, it should be waterproof, dustproof and insectproof. At the same time, it is necessary to avoid placing it in an environment with corrosive gases and liquids, so as to prevent the internal aging of the machine or damage to its components, which will affect the life of the machine.

The above is how to choose the point of full-band signal jammer. With this knowledge, you can choose the appropriate spot according to the actual situation, optimize the shielding effect, and ensure a fair test environment.
