Jammers most commonly operate in the CDMA, GSM, DCS, PHS and 3G ranges


Mobile phones have conquered the market and now their annual sales are increasing. The ability to stay in touch at all times, as well as additional features such as taking photos and videos, listening to your favorite tracks, surfing the internet, and playing games, make mobile phones an indispensable tool for almost every resident of the country.

However, in addition to useful features, mobile phones also have negative impacts that users often forget. These include making phone calls in cinemas, meetings, or other clearly inappropriate places that interfere with others' normal activities. When the neighbor's phone rings in the theater, everyone gets angry at least once.

But not every user is well aware that their phone can also be used as a listening device, which may leak important information. To prevent this from happening, you can use a signal suppressor.

Communication signal jammer (blockers, suppressors) are special devices designed to ensure information security. With their help, you can completely eliminate the possibility of using mobile phones and cellular communication to make calls or listen to conversations. But in order for the muffler to work properly, you should understand the characteristics of its selection.

Jammers can operate in completely different ranges, but are most commonly used - CDMA (operating frequencies from 869 to 894 MHz), GSM (operating frequencies from 925 to 960 MHz), DCS (operating frequencies from 1805 to 1880 MHz), PHS (operating frequencies from 1900 to 1990 MHz), and 3G (operating frequencies from 2010 to 2170 MHz). Due to this, these devices can overwhelm the work of almost all modern digital devices. When making a purchase, you should pay attention to the available channels, quantity, and availability of necessary channels.

The radius of activity is a key characteristic, as the efficiency of working in large spaces will depend on it. Today, the production equipment can cover an area of 5 to 25 meters. But the larger the radius, the faster the battery consumption.

The existence of radio frequency paths provides necessary selectivity and reduces the possibility of mutual interference.

Battery operation makes the suppressor easier to move, but its operating time will be short. That's why being able to connect to the network is important.

Communication signal jammer are the only way to protect oneself in important events.
