Several full-band frequency jammers need to be installed in an examination room

How many full-band frequency jammer should be installed in a classroom? Every year when the college entrance examination is approaching, before this important day, the staff in charge of the college entrance examination examination room are actively preparing for the various materials needed for the examination room. There is also a mechanical device called full-band frequency interference. Instrument, this kind of machine can ensure the order of the examination room, maintain a good environment, and effectively isolate all communication signals in the examination room. Electronic signals are an increasing information transmission tool today. If you want to isolate the signal, you need to install a full-band frequency jammer. But faced with the problem of installing a full-band frequency jammer, many schools are thinking about how many machines should be equipped in a classroom?

To solve this problem, we must first consider the actual interference effect of the full-band frequency jammer, because it does not matter whether there is a base station within 300 meters, and whether it is used through the wall. In general, if there is no base station within 300 meters and it is used in an open area, then a classroom probably needs a machine, but it depends on the actual usage. This cannot be guessed and can only be known in actual use. , so the examination room that is worried about this aspect can borrow a full-band frequency jammer to test the jamming effect on the spot. This also does the trick.

Generally speaking, many people have doubts about the purchase of full-band frequency jammers. At this time, they need to consult professional manufacturers. Therefore, you are welcome to consult with topsignaljammer Technology Co., Ltd. about full-band frequency jammers. The company has professional The technical team provides technical support for products, and is more focused on the production and research and development of jammers. It has many years of high-quality experience and is trustworthy and cooperative.

The communication principle of the 5G mobile phone signal jammer scans from the low-end frequency of the forward channel to the high-end frequency at a certain speed during the working process. The scanning speed will cause garbled code interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent by the base station, resulting in the failure of the mobile phone to establish a connection with the base station. The mobile phone is characterized by searching the Internet, no signal, and no service system.

Our mobile phones must emit electromagnetic waves that meet the requirements in order to access our communication operator's base station. Different communication systems use different frequencies so that everyone can live in peace without interfering with each other.

The basic principle of the mobile phone jamming device is to transmit the same radio frequency signal as the mobile phone. Since the frequency is the same, the mobile phone cannot distinguish which signal is a conventional base station signal, thereby achieving "jamming". As long as there is a machine with the same frequency as the phone, when the base station tries to connect to the phone, there will be a lot of "noise", and you will find that the signal from the phone cannot be recognized.
