  The shielding range of the mobile phone signal shield is determined by the power of the shield. However, in some examination halls where mobile phone signal blockers are used, some parties (invigilators, examinees and teachers of the college entrance examination) are upset and powerless . attentively. Even headaches. The mobile phone signal shield we set during the provincial and county economic work conference was placed in the flowers on the floor next to the wall of the conference room, which not only achieved the shielding effect, but also did not affect the beauty of the site.

  Then GSM signal is close to outdoor shielding range! The theoretical analysis shows that when the mobile phone signal shield is working, if the transmission power is too large due to improper setting, in small conference rooms, classrooms and other confined spaces, the electromagnetic wave will overlap in a narrow space, and the electromagnetic wave will pass through the wall originally separated from the outside.

  All kinds of signs indicate that the transmitting power of the mobile phone signal shield is too large, which will seriously affect the normal thinking of examinees in the examination room. If it is a field test, the local environmental signals are different according to the strength of the shielding range.

  When it is really necessary to use an gsm jammer, try to use a low-power mobile phone signal jammer. A house of about 100 square meters is enough. Multiple reflections from the ceiling and the ground will lead to more serious electromagnetic pollution when people in the room are exposed to the outside. For example, the weak shielding range of indoor signals is large, and there are GSM base stations for outdoor use. According to the survey, the college entrance examination and the high school entrance examination are the places where mobile phone signal jammers are most used.

  It can be said that it is very bad for human health. The range of the cell phone signal blocker depends on the range of your FM. If one can solve the problem, do not set more than one. The lower the installation position, the better. Otherwise, how can the prison achieve all signal shielding.
