why not buy same wave bubble rf jammer for yourself

Cellular phone blockers can be used in hospitals, churches, movie theaters, theaters and other places where using a cell phone may leak sensitive information. In this case, its operation does not interfere with electronic medical equipment (for example, a pacemaker), and mobile phones can make emergency calls. cell phone jammer are retained by the police, used by the police, and tested in prisons, and are being used in more and more fields.Some people are very confused. In the face of more and more cheating techniques in school examinations, it is difficult to stop them only by traditional means.

cell phone jammer cut off all mobile radio waves, including smartphones, because Wi-Fi and Bluetooth cannot pass, making communication almost impossible. The mobile jammer did not block, but issued a "pseudo base station radio wave", forcing the mobile phone out of range. Since the fake base station radio has no location information or line type information, communication cannot be performed even if the fake radio broadcast is received through a mobile phone, so the line was determined to be unavailable and was judged to be service interrupted .

Where GPS signals are unreachable or difficult to reach, the location information will be checked against the base station of the mobile phone operator. In this case, the location information will be relevant, but you will know where you are right now. In order to completely disable the GPS signal, the mobile phone must be stopped, that is, using a mobile phone GPS jammer.In this case, the school is the first to use a mobile phone signal jammer to deal with cheating on rogue mobile networks and using technologies such as Bluetooth, which works well.
