To install a dedicated cell phone jammer in a place with limited radio waves, we are planning a powerful over-range jamming device. It is a reasonable decision to place the theater or station outside the area. Suppress the communication function of the mobile phone within a certain range, the effect is usually good. In some cases, you may want to make a call so that you cannot use the phone.
Be careful when using cell phone jammers. This is a precaution for some jammers. Due to factors such as differences in the performance of various jammers, PHS phones may take some time to stop using. In certain areas, it may be difficult to disconnect the cell phone signal closer to the base station. Depending on the brand and model of each phone, performance will vary and the effect may vary.
There are some precautions to take to avoid interfering with other people’s mobile phones. Please avoid dismantling, altering and providing illegal products, as this is a criminal offence in violation of the Radio Law. The effective range may be narrowed depending on the specification environment. In addition, depending on the phone manufacturer, some things are easy to respond to, while others are difficult to respond to. In fact, some countries prohibit the use of cell phone jammers.
