Jammers are the easiest way to protect yourself

Although wireless networks allow people to easily access the Internet, the problems caused by wireless networks 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 begun to install this desktop wifi filter to protect the network security in certain places and prevent excessive use of the network. The device has been widely used in various countries and regions in the world. It is a typical representative of schools, prisons, libraries, reading rooms and gas stations.

A simple way to protect yourself with a portable jammer is to purchase a universal portable telephone shield in our store. The device can mute the radio signal at a sufficiently large distance. They are usually used in public places, conference rooms and leading offices. The GSM signal blocker can be portable or fixed, thus eliminating the cellular communication channel, wireless camera and microphone communication channel. The range of such equipment depends on many factors: these equipment only interfere with the specified frequency, so any other equipment within its operating range will work as usual. For example, if the GSM network is muted, Wi-Fi will work. The jammer has no effect on any other equipment or personnel.

Sometimes, people may need to truncate signals in different frequency bands in different situations. At present, a jammer with adjustable function will be a good choice. Because it allows you to select the desired interference frequency band, other frequency bands will not be affected and can continue to be used.If you need a high-power 3G signal mobile phone jammer, you can meet your needs.

Therefore, the design has high power, and the interference range of the adjustable GSM 3G signal jammer can reach 40 meters.
