Is there a difference between mobile phone signal jammers when used outdoors and indoors?

There is a difference between indoor and outdoor mobile phone signal jammers. For example, Greatjammer jammer SQ-B35 mobile phone signal jammer, you put the same power in the room, and there are walls around the house to block the signal from the base station, so see The effect is much better. The Greatjammer jammer SQ-B35 mobile phone signal jammer is placed outdoors, there is relatively no obstruction outdoors, the base station signal is also stronger, and the coverage distance is slightly closer. It is generally recommended to use Greatjammer SQ-B30 high power jammer for outdoor use in playgrounds, prison squares, and large open areas!

The effective shielding distance (30-40 meters) of the mobile phone signal jammer generally refers to the indoor distance. In an open outdoor area, the effective distance of shielding can reach several hundred meters. It should be pointed out that whether it is used indoors or outdoors, the effective shielding distance of the jammer has a certain relationship with the environmental conditions at the time, such as the distance from the base station, and the location where it is placed. Therefore, when using a mobile phone signal jammer, this factor should be fully considered to avoid shielding dead angles that affect the shielding effect.

First of all, the effect comparison must be the same mobile phone signal jammer, because the effect of different power mobile phone jammers is different, and the comparison is meaningless. Secondly, because indoor and outdoor signal strengths are different, the shielding distance of the signal jammer must be different, but it is impossible to distinguish who is near and who is far. If a signal amplifier is installed on the indoor ceiling, but there is no outdoor nearby, then the distance used for the jammer must be smaller indoors than outdoors. On the contrary, if there is no signal amplifier indoors, regardless of whether there is outdoor, the effect of the jammer must be stronger indoors than outdoors. Of course it must be an empty room indoors.
