Mobile phones are communication and entertainment products. The rapid development of science and technology has greatly improved the appearance and functions of smart phones, and more and more people use mobile phones. signal jammer that block cell phone signals 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 jammer preventing the CDMA mobile phone network is smaller than that of GSM mobile phones, but the difference is not much. If necessary, the number of mobile phone signal jammers can be increased to ensure the effect of traffic jams. In some particularly important places, the shielding effect of CDMA mobile phones is very good.
There is a small WiFi Bluetooth jammer, a wireless LAN transmission signal and a mobile phone signal jammer for market surveillance. Adopt advanced foreign technology, work 24 hours a day, 365 days a day, imported parts used for communication suppression equipment, and improved domestic mobile communication with power supply based on advanced high-tech products. It is strongly recommended for school test rooms and 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 opened and closed, and the intensity can be adjusted. In some countries/regions, blocking radio waves without the permission of the communications department may violate the Radio Law. It is difficult to implement this method when you don’t want to use a mobile phone or need a quiet room, and it’s also difficult to improve this method only by attracting viewers. However, when I was reading on the train, people around started stealing my personal mobile phone network, which is very dangerous for protecting personal information.
