There is no set value for the interference range of a mobile phone signal jammer. It depends on how far it is from the base station in the environment, whether it is used indoors or outdoors, whether it needs to penetrate a wall, etc. Only by understanding these can we better choose a suitable mobile phone signal jammer.
Interference distance in an ideal environment (no base station or signal amplifier for surrounding signals): The normal market price is less than 1,000 yuan. The interference range of a low-power mobile phone signal jammer is 0-50 meters, with an area of about 10-250 square meters (non-fixed value, according to The interference effect varies depending on the distance between the site and the base station, and the shielding range is mainly determined by the strength of the magnetic field). Low-power mobile phone signal jammers are small-range interference products. They are only targeted at open areas and have weak wall penetration capabilities.
There is a signal base station nearby and a signal amplifier is installed in the building: many customers have called me to say that I need a mobile phone signal jammer that can shield a radius of 50 meters, a distance of 500 meters, and a radius of one kilometer. Is there a problem with the customer's request? No problem, and specific distance requirements are given, but can it be achieved? The answer is that it is difficult to implement.
The frequency emitted by the mobile phone signal jammer interferes with the frequency of the mobile phone receiving the base station. There is destined to be a competition between the jammer and the base station. If the transmit power of the mobile phone signal jammer is less than the channel power delivered to the mobile phone by the base station in the current environment, then the interference will The signal jammer cannot be shielded. Only when the power of the mobile phone signal jammer is greater than the power delivered to the mobile phone by the base station can it effectively interfere. Therefore, any mobile phone signal jammer will show different shielding distances when used in different signal environments. The density, location and power of base stations built by different 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 technicians to you for model recommendation and on-site testing.
You need to clearly understand your surrounding environment and the size of the place of use before deciding on the number of mobile phone signal jammers to purchase.
