When testing the interference effect of the mobile phone signal jammer, people often encounter some problems, which are quite incomprehensible. That is, when the same mobile phone signal jammer is tested in different places, the interference effect will vary greatly. What is the reason for this situation? Next, I'll give you some popular science.

What many people do not know is that there is such a device, which may have a serious impact on the effect of the mobile phone signal jammer, that is, the interference range. This is a problem that every user of the mobile phone signal jammer needs to consider.

What is this device? It is the base station of the operator, commonly known as the signal tower, because if there is a base station near the use site, the interference effect of the mobile phone signal jammer will be affected. Of course, this means that the signal strength from the base station within 500m around the site to the site will be very strong, so the interference range of the mobile phone jammer will be reduced. If the base station is 500 meters away from the examination room, the impact on the mobile phone jammer is very small. As for the reason why the influence is caused, it is because the base station itself will carry strong electromagnetic signals when transmitting signals to the surrounding areas. The electromagnetic signals transmitted by the base station will decrease with the increase of distance. The strength of the electromagnetic signal field is one of the most important factors affecting the interference effect of the mobile phone signal jammer.
