Different environmental interference effects are also different. The interference range in open areas is greater than in areas with many buildings. This is why the measured interference radius is usually better than the actual range. Because the test is in the open. Equipment reliability will be low as the signal will be blocked/interfered by stone walls, grids forming Faraday cages (including "fake" lead windows) and metals such as tin foil insulation, interfering with indoor coverage areas. This means that if you're using Mount Spokane Cell Phone Blocker Police Radio indoors, the walls may cause glass to block the signal and prevent it from interfering with the signal in another room. First, when the cell phone jammer was built, it was tested. There are many necessary tests, such as battery life, transmission frequency, etc., including the interference radius test.
Because these devices are often tested in open areas, manufacturers consistently assume that test results are more valid than they actually are. You know buildings and various concrete structures can interfere with signal transmission. Most of us live in big cities surrounded by skyscrapers. The signal strength of the local cell phone is also a factor. So don't be surprised if a jamming device doesn't block calls within 30 meters. In this world, there is always someone who can come back from the dead and create new heights. This is especially true for Americans. Although they usually seem to be more playful, once this kind of thing is used in the wrong place, it becomes a real life and death. And now, there is such a person, how will he die the most thoroughly. We all know that there is a thing called Mount Spokane Cell Phone Blocker Police Radio in this world, I believe everyone is familiar with it. When we were in school, it was always in a corner of the classroom as one of the teachers' ultimate weapons against their students. Block all signals and smash students' dreams of "relying on Baidu exams".
