Have you ever encountered such a problem that you have installed a radio frequency jammer, but the signal source of the base station is about 100 meters away. Can the jammer still interfere on such a site?

In this case, it can basically be determined that the test room cannot be interfered with by installing a jammer. The distance between the base stations is too close, and the signal from the base stations to the site is very strong. A low-power radio frequency jammer is basically ineffective at this site. Even if a high-power wireless frequency jammer is used, the interference range may not meet the requirements of the site, and it is unlikely that an examination room is equipped with too many high-power machines. After all, the cost is too high.

The reason why the jammer can interfere with the cell phone signal is that the signal transmitted by the jammer and the cell phone signal transmitted by the base station are white noise signals in the same frequency band. This white noise is also called interference signal. Within the coverage range of the jammer, the wireless signal strength is submerged by the interference signal, and the cell phone cannot recognize the signal of the base station, so the cell phone cannot connect to the base station, and the cell phone cannot log in to the base station, Of course, you cannot enjoy the services provided by the BTS.

Is there any way to interfere with mobile phone signals? You can try to coordinate with the base station operator to adjust the transmission power of the base station, or adjust the direction of the antenna on the base station so that the antenna is not facing the site. This is to reduce the on-site signal strength, so as to play the real role of the radio frequency jammer. Normally, you can only coordinate processing from the perspective of the base station. The purpose of adjusting the base station is to reduce the strength of the on-site mobile phone signal. At this time, the radio frequency jammer can be used to interfere with the mobile phone signal.
