Some individual customers often ask us about the performance requirements of mobile phone signal jammer that need to be used outdoors: when used outdoors, the effective interference distance should reach tens of meters or even hundreds of meters. Those who can meet this requirement must be high-power mobile phone signal jammer, but when it comes to the price of high-power jamming devices, these individual customers are often intimidated, because, at the price they expected, it actually belongs to The price of low-power mobile phone signal jammer. Moreover, their original idea was to use low-power interference devices. Even if the use environment was changed to the outdoors, the interference effect should be similar. So, is this the reality? How much difference is the effect of mobile phone signal jammer used indoors and outdoors?

The conclusion we give is: If you use the same cell phone signal jammer, when used indoors and outdoors, the effect of the two will be very different! Moreover, in these two use environments, low-power mobile phone jamming devices are generally used indoors, and high-power mobile phone signal jammer must be used outdoors.

The difference between indoor and outdoor is the difference in the strength of the received signal from the base station. The outdoor signal strength is generally more than ten dB higher than the indoor signal strength, or even more. This depends on the wall material of the building, the size of the doors and windows of the building, and the distance from the base station. A low-power mobile phone signal jammer can effectively interfere more than ten meters indoors, but when it is used outdoors, the effective interference distance may be less than 3 meters.
