How is the performance of cell phone signal jammers in penetrating walls?
Can cell phone signal jammers shield through walls? To answer this question, we need to look at several situations. First, let's look at the cell phone signal jammer itself. The mobile phone jammer transmits a wireless radio frequency signal specifically for mobile phone signals. When it encounters a wall in the transmission path, part of the signal will be reflected back, and part of the signal can directly penetrate the wall, but the signal strength will be attenuated to a certain extent. And facing different walls, the attenuation degree of mobile phone jammers is also different. For example, the wall is a reinforced concrete wall or a brick-concrete wall. If there is a reinforced concrete wall and two consecutive brick-concrete walls, the interference signal emitted by the mobile phone signal jammer is basically attenuated, that is, it cannot be used through the wall. Therefore, the signal emitted by the mobile phone signal jammer usually cannot penetrate the wall. After al
