Jammer Signal

For teaching buildings below the 2nd and 4th floors, when configuring high-power mobile phone signal jammers, they also need to be installed in the front and back of the teaching building, and the number of configurations should be determined according to the strength of the mobile phone signal on site. Under normal circumstances, at least 2 sets of high-power mobile phone signal jammers are required. The cost of high-power mobile phone signal jammers is far higher than that of low-power mobile phone signal jammers.

Therefore, to sum up, it is not recommended to use a high-power mobile phone signal jammer in a 6-story teaching building. The most cost-effective way is to install a low-power mobile phone signal jammer in each classroom, and it can also be connected to the Internet for unified control and management through software.n Recently, a customer inquired whether the police jammer should be equipped with an omnidirectional antenna or a directional antenna when in use. The police frequency jammer is mainly used for auxiliary equipment used by the public security to deal with some special tasks. For example, the police jammer will be used in tasks such as gathering group events, temporary communication control, and arrest of suspects.

Police frequency jammers are generally portable and can be designed as a drag box or backpack. Under normal circumstances, police jammers are equipped with omnidirectional antennas. The advantages of police frequency jammer equipped with omnidirectional antennas are as follows: : 1. It is easy to carry. The omnidirectional antenna is basically a glass fiber reinforced plastic shell. When carrying, just put the antenna in the storage bag. It is best to use a special storage air box for the antenna, which takes up less space and does not need to worry about bumping. 2. Quick disassembly and assembly. When the police arrive at the mission site, they only need to connect the frequency band of the omnidirectional antenna to the frequency band interface of the police jammer, so as to tighten the omnidirectional antenna. It is also very convenient to disassemble. The antenna can be put into the storage bag. It is especially suitable for application scenarios when the police handle the above tasks.

And if the police jammer chooses to be equipped with a directional antenna, it is too inconvenient. The directional antenna is relatively bulky, inconvenient to carry, and takes up a lot of space. It is necessary to carry not only the directional antenna, but also the mounting bracket for the directional antenna, which is also a problem to store. And when disassembling, you need to install the directional antenna on the antenna bracket first, and then connect the police frequency jammer host through the feeder. When the police deal with the above tasks, the preparation time is relatively long, and the operation is relatively cumbersome. Therefore, directional antennas are not suitable for police to use when dealing with outdoor tasks.

The directional antenna is suitable for use in some fixed places. It is only necessary to set up the antenna and adjust the coverage angle before installing the device and the antenna. Use the feeder connection between the antenna and the device host to tighten, and then it can be used normally. We have to go through many exams, including high school entrance exams, college entrance exams, postgraduate exams, etc., CET-4 and CET-6 exams, various qualification certificate exams, and the annual civil service exam, etc. In the exam room, the most common exam room auxiliary equipment is to prevent cheating Cell phone jammers.
