Block A Number From Your Cell Phone

The mobile phone signal jammer is one of the indispensable equipment for examination rooms, prisons, gas stations and other places. Its function is to shield the mobile phone signal and make the mobile phone unable to operate normally. Judging from the size of the examination room Block A Number From Your Cell Phone , it is not very big, and it can be conveniently placed in any position in the examination room without the need for additional space. And there is no noise, and the use of mobile phone jammers will not have a big impact on the candidates. In addition, there is no need to worry about its impact on other electronic equipment, it is mainly to shield the mobile phone signal. At the same time, it is used to cut off the connection between the mobile phone and the base station, and will not cause harm to the human body. At present, with the development of science and technology, the range that this kind of mobile phone signal jammer can cover becomes wider and wider. A large area can be covered at one time, so the cost is greatly reduced. cell phone jammer Using signal jammers to shield wireless signals in secret places is a basic security measure. However, the development of mobile communication technology and the construction of mobile networks have brought great challenges to # in secret places, which are mainly manifested in: Mobile communication and wireless systems adopt a variety of advanced anti-interference technologies. Such as: spread spectrum, frequency hopping, diversity, advanced coding, and anti-interference capabilities are getting stronger; the same place is covered by the wireless signals of multiple mobile communications and wireless systems, and each system uses multiple frequency bands, resulting in more and more frequency bands The more the bandwidth, the wider the bandwidth; the wide deployment of indoor base stations greatly improves the indoor signal strength. However, most of the current mobile phone signal jammers use sweep frequency interference methods, which have higher requirements for interference signal ratio.

Mobile phones have become a modern mainstream communication tool, which facilitates daily life, and is also very common on university campuses, but this will cause problems for classroom management. In order to manage students, the school installed portable high-power Block A Number From Your Cell Phone in some classrooms. Some school administrators have introduced other types of shielding equipment. In the future, we will further expand the control of class suspension signals, and plan to introduce a way to
