Due to various factors, for example, the location is relatively close to the base station, resulting in strong local environmental signals. At this time, the effect of the general shield is not very obvious, and it is afraid that the shielding is insufficient and the function is relatively single. Therefore, a high-power shield will be considered at this time. The high-power Signal Jammer uses reasonable methods to transmit ultra-high-power shielding signals to ensure that each frequency band can be fully covered and reasonably avoid other electronic signals. It is applied in prisons, large open areas, secret places and other places.

The design structure of high-power Signal Jammer will be different, and it may be much larger in appearance. Most shielding equipment will choose to use external antenna, which occupies a large space and has a long shielding distance. Of course, the shielding effect is relatively stable. Generally, in the classroom and during the examination, the ideal effect can be achieved by using low-power shielding equipment. The strength of high-power Signal Jammer should be more suitable for open areas. Places such as playground can be shielded in a wide range, which can reach a certain distance and have the ability to pass through the wall. Understand which frequency bands are shielded. Generally, mobile phone signals can be shielded before leaving the factory, and manufacturers can also be asked to shield other frequency bands, such as WiFi, UAV, walkie talkie, etc. These requirements can be met by manufacturers.
