What factors will affect the shielding range of wireless signal jammers?

For all kinds of school examination rooms, supervision places, and secret-related units, wireless signal jammers are a very common device, because in some cases where mobile phones need to be shielded, wifi signal jammers will inevitably be used. So in order to ensure the full coverage of the shielded area of ​​the jammer, in what environment can the wireless wifi frequency jammer be installed and the effect is better. And why sometimes the installation of the jammer does not have the shielding effect or the effect is very poor? In fact, this is closely related to the environment in which it is used. When using a jammer, the following factors must be considered:

① Distance from the base station: Since the jammer blocks the connection between the base station and the mobile phone by transmitting interference signals during operation, the closer the mobile phone is to the base station, the higher the shielding difficulty, the effective shielding range of the jammer is also smaller

②Environment of the shielded area: The decoration materials of the house and the shielding effect of the building itself, as well as the proportion of indoor metal and non-metal, make the shielding range of the wireless wifi signal jammer greatly reduced after passing through the wall.

③The size of its own power: the larger the power of the device, the larger the shielding range, and the smaller the same power, the smaller the shielding range.

Generally, it is used in an open environment, that is, there is no signal tower within a distance of 500 meters. If there is a base station or a wall, the shielding distance will be difficult to reach a reasonable range, so the use depends on the specific situation.
