First of all, it is necessary to clarify what place is used. Generally, the wireless frequency jammer of the examination room type is used in the school, because it is more suitable for long-term work and is more durable. Secondly, how big is the area that needs to be shielded? If the area is larger, you should choose a larger power point, and if the area is small, you can choose a smaller shielding power. Also, which frequency bands need to be shielded, are China Mobile, China Unicom, and Telecom all shielded? Still just need to block some frequency bands.

At this point, we recommend that you want to achieve the best results after purchasing a wireless frequency jammer, depending on the method used. There are:

①Indoor bluetooth signal jammer is recommended to be placed at a height of about 180cm-250cm, preferably with an angle of forward tilt.

②Whether there are obstructions (such as walls, metal products) between the jammer and the mobile communication equipment. The interference signal emitted by the radio frequency jammer will be attenuated to varying degrees after passing through the obstruction, please try to avoid it.

③The farther the environment where the jammer is applied is from the base station, the stronger the shielding effect of the jammer will be.
