The jammer creates a quiet environment for you

Most of today’s electronic devices are mobile phones, which are communication and entertainment products. The rapid development of science and technology has greatly improved the appearance and function of smart phones, and people using mobile phones are very common. A signal blocker, cell phone signal blocking can create a quiet environment for people. More and more people are reading books and newspapers on the subway, and spending too much time on smartphones is not good for us.

Since the anti-interference performance of CDMA mobile phones is much better than that of GSM mobile phones, the portable jammer to prevent CDMA mobile networks are smaller than GSM mobile phones, but they are not much different. If necessary, the number of mobile phone signal interference transmitters can be increased to ensure the effect of traffic congestion. In some particularly important areas, the shielding effect of CDMA mobile phones is very good.

There is a small WiFi Bluetooth jammer, a wireless LAN transmission signal and a cell phone jammer for market surveillance. Using advanced foreign technology, 24 hours a day, 365 days of continuous work, using imported parts of the communication suppression device, improved domestic mobile communication with power based on advanced high-tech products, highly recommended for school test rooms, dormitories, libraries , Prisons, camps, military, troops, churches, secret meeting rooms, etc.

The angle of the signal interference antenna can be adjusted freely. According to the interference frequency, each stop band can be turned on and off, and the intensity can be set. In some countries, blocking radio waves without the permission of the communications department may violate the Radio Law. When you do n’t want to use a mobile phone or need a quiet room, it is difficult to implement this method, and it is difficult to improve it by simply attracting viewers. However, when I was reading on the train, people around me started stealing my personal mobile phone network, which was very dangerous for protecting personal information.
