The portable Bluetooth jammer is a special design for confidentiality based on current mobile phones (with wireless network, Bluetooth, wireless transmission, etc.) and tracking (locomotive, mobile phone location, Google network location, etc.). And personal inconvenience. , In view of all current GPS satellite positioning systems and wireless frank characteristics, the GPS satellite signal and wireless frank transmission signal are effectively intercepted within the radius of 5-20 meters using this product, forming an effective protection area, so you don’t have to worry about whereabouts Be tracked.

Wireless communication must ensure sufficient carrier-to-interference ratio (signal-to-noise ratio) in order to receive effectively and complete communication. The mobile communicator destroys the reception conditions of the mobile phone and cuts off the communication connection between the mobile phone and the base station by generating interference signals with the same frequency as that of the mobile phone. To achieve the effect of shielding communication.

The jamming power of the jammer is fixed, and the shielding radius of the unobstructed space is determined by the path attenuation and the signal level of the receiving base station. The following table shows the comparison table of distance and path attenuation. Then the coverage radius can be determined by the output channel power of the jammer, the base station signal level, and the coverage line gain.
