Ow To Block Unknown Calleers From Cell Phones Focus

The basic theoretical analysis shows that when Ow To Block Unknown Calleers From Cell Phones is working, if the signal strength is too high due to unreasonable settings, in a closed indoor space such as a small-scale conference hall, classroom, etc., the radio waves will accumulate in the narrow indoor space, according to The walls, suspended ceilings, and road surfaces that were originally separated from the outside have several reflection surfaces, which will expose the staff in the room to relatively serious electromagnetic radiation. According to the research, the college entrance examination, junior high school and high school are the places where many mobile phone signal jammers are used, and in some test rooms where cell phone jammer is used, some defendants (gaokao inspection staff, students and teachers) are upset and cannot concentrate their energy. In some cases, some students even suffer from headaches. There are many indications that if the signal strength of the mobile phone signal jammer is too large, it will seriously endanger the normal thinking of the students in the examination room.

To put it bluntly, the high efficiency of shielding means whether there are blind spots and loopholes in the actual effect of shielding. Around some prisons, it is very likely that there are transmitting communication base stations with strong mobile phone signals. In order to better achieve a very good shielding effect, it will take a correspondingly large amount of raw materials and vitality, and the cost will be corresponding. will be greatly increased. Therefore, the better the actual shielding effect, the higher the cost. In specific applications, the Ow To Block Unknown Calleers From Cell Phones shielding regulations in the prison area are generally higher, with slight loopholes and blind spots. The staff who violate the regulations are likely to grasp the loopholes in this system, so that the originally required shielded areas can be used on mobile phones. It is impossible to shield the original intention on the mobile phone.
