What is the minimum blocking range of a mobile phone signal jammer? from YIFALIU's blog

Generally speaking, the minimum range of a signal jammer is tens of meters in radius. As long as there are enough jammers, the maximum range is unlimited. Otherwise, how can the prison shield all signals? The range of the mobile phone signal jammer depends on your frequency modulation range. One unit is enough for a house of about 100 square meters. Shenzhen Texin Electronics has a variety of jammers that you can check out.

The shielding range of a mobile phone signal jammer is based on the power of the jammer. If tested in the field, the shielding range will be different depending on the strength of the local environmental signal. For example, the shielding range will be larger if the indoor signal is weak. What are the GSM base stations for outdoor use accessories? Then the GSM signal is within the outdoor shielding range!

Theoretical analysis shows that when the mobile phone signal jammer is working, if the setting is improper and the transmission power is too large, in a small conference room, classroom and other closed spaces, the electromagnetic waves will be superimposed in the small space and pass through the walls and walls that are originally separated from the outside. Multiple reflections from the ceiling and the ground will expose people in the room to serious electromagnetic pollution. According to the survey, the college entrance examination and the high school entrance examination are the occasions where mobile phone signal jammers are used the most. In some examination rooms where cell phone signal jammers are used, some parties (college entrance examination inspectors, candidates and teachers) become irritable and unable to concentrate. Some candidates There may even be headache symptoms. There are various indications that if the transmission power of the mobile phone signal jammer is turned on too high, it will seriously affect the normal thinking of the candidates in the examination room.

When you really need to use a jammer, try to use a low-power mobile phone signal jammer. If one can solve the problem, do not install multiple jammers. The lower the installation position, the better. Do not hang it above people's heads. This is very harmful to human health. The mobile phone signal jammer we set up during the county economic work conference in the province was placed among the flowers on the ground beside the wall of the conference room. It not only achieved the shielding effect, but also did not affect the beauty of the venue, which can be said to be the best of both worlds.
