I recently received a consultation from a customer, and the college entrance examination is about to take place. I need to use a mobile phone signal blocker. However, because there is a Unicom base station within 300 meters of the school examination room, the previous signal blocker is not very effective. It is just now that it can block 5G mobile phones. Signal jammer, is there any suitable full-band Microwave Block Cell Phone Signal recommendation? There is a Unicom base station within 300 meters of the test room. This distance can be said to have a relatively large impact on the shielding effect of the signal jammer. In this case, it is necessary to use a mobile phone signal jammer with a higher power to ensure the shielding effect. In the process of domestic college entrance examination, adult college entrance examination, self-study examination and various colleges and universities, some criminals use mobile phones to cheat. According to the actual situation of domestic mobile communication, a high-tech product has been carefully developed and can be used in a radius of 1-30 meters. The range cuts off the mobile phone signal and WIFI wireless signal, so that the mobile phone cannot talk and surf the Internet, and the WIFI cannot work normally.

The development of smart phone wireless network plays an important role in improving the speed of development. Mobile phones can solve network problems, and mobile phones play a more important role in people's life, mobile communication and mobile Internet. Because of this, it caused a lot of problems. Especially in the home network, children are addicted to the network mainly because of the wifi network. Therefore, many families gradually began to install Microwave Block Cell Phone Signal to block the Internet in order to control their children's Internet time. 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 access to the network, but also of network security. In order to maintain a good network environment, Cell Phone Jammer is installed in many places to prevent the network from being overused. This equipment has been widely used in countries and regions around the world. Schools, prisons, libraries, reading rooms and gas stations are typical examples.
