What is the interference distance of cell phone signal jammers?

The jamming range of cell phone jammers is always blurry. Is there a more scientific explanation and what is the scope?

How much range can cell phone signal jammers interfere with?

There is no fixed value for the interference range of the phone signal jammer. It is far from the base station in the environment, and then whether it is used indoors or outdoors, whether it needs to pass through the wall, etc. Only by understanding these can you better choose the right cell phone signal jammer.

Interference distance in ideal environment (no signal base station around, no signal amplifier): the normal market price is below 1000 yuan, the interference range of low-power mobile phone signal jammer is 0-50 meters, and the area is about 10~250 square meters (non-fixed value, according to The distance of the site from the base station is different, and the interference effect is different, and the shielding range is mainly determined by the strength of the magnetic field). Low-power mobile phone signal jammers are small-scale interference products, only for open areas, and have weak ability to penetrate walls.

There is a signal base station nearby, and a signal amplifier is installed in the building: Many customers called and said that I needed a mobile phone signal jammer with a radius of 50 meters, a distance of 500 meters, and a radius of one kilometer, and the signal of each communication operator was required. can be blocked. Is there a problem with the client's request? No problem, and specific distance requirements are also given, but can it be achieved? The answer is not easy to implement.

The frequency emitted by the mobile phone signal jammer interferes with the frequency of the mobile phone to receive the base station. The jammer and the base station are destined to be a contest. If the transmission power of the mobile phone signal jammer is less than the channel power delivered by the base station to the mobile phone in the current environment, then the interference Only the power of the mobile phone signal jammer is greater than the power delivered by the base station to the mobile phone, so that effective interference can be achieved. Therefore, any mobile phone signal jammer will show different shielding distances when used in different signal environments, because the base station density, base station location and base station power built by communication operators cannot be the same. Therefore, in this case, medium and large mobile phone signal jammers are generally used, and professional customer service is required to recommend suitable equipment and technical personnel for model recommendation and on-site test machine.
