The wireless network facilitates people's access to the Internet, but the problems caused by it cannot be ignored. This is not only a problem of accessing the network, but also a problem of network security. In order to maintain a good network environment, many places have installed wifi shields to prevent excessive use of the network. This equipment has been widely used in countries and regions around the world. Schools, prisons, libraries, reading rooms and gas stations are typical representatives.

Generally speaking, the frequency emitted by the signal jammer interferes with the frequency of the mobile phone to receive the base station. There is a competitive relationship between the jammer and the base station. If the transmission power of the signal jammer is lower than the power delivered by the base station to the mobile phone in the actual environment, then the shield The shielding device cannot be shielded, so effective shielding can be achieved only when the power of the signal shielding device is higher than the power delivered by the base station to the mobile phone.

British "Jane's Defense Weekly" reported on August 15 that due to the increasing commercialization of drones, the threat to military and civilian targets is also increasing. With the increasing popularity of cheap and easy-to-operate drones around the world, there is an urgent need to develop anti-UAV (C-UAV) systems to deal with this threat. This trend can be seen from the recent vigorous development of drone jammer, and the European Defense Exhibition held in Paris in June this year also emphasized this trend.

When the cell phone jammer works, it only shields the cell phone signal and does not affect other electronic devices. At the same time, the radiation generated is very small and will not cause harm to the human body. Studies have shown that long-term use of mobile phones not only damages eyesight, but also interferes with sleep, affects social interaction, and causes rashes. Especially for children at home, shielding mobile phone signals at home allows children to have more learning time.

Cell Phone Jammer is used in many places. If you need to be quiet, you can turn on the jammer and the phone is in signal state to avoid the interference of the phone ring. Of course, jammers are also used in many areas, such as classrooms, which can be used to help prevent student fraud. Prevent jammers from interfering with radio and external jailbreak communications in prisons. This is a very useful tool to prevent signal propagation. We recently designed a variety of jammers for UAVs. These jammers can be very good for drone interference to prevent unmanned The machine seizes privacy.
