GSM is a variation of TDMA and is the most widely used of the three digital wireless technologies, i.e., TDMA, CDMA and GSM. This system operates at 900 MHz and 1800 MHz.

When selecting a frequency disruptor device, it is important to make sure that device’s disruption output has been designed to disrupt several different transmission types used by wireless network service providers. If the device only disrupts a limited number of transmission types, the GSM jammer may not perform as expected on the street. To better ensure the best performance, it is strongly encouraged that the frequency disruptor disrupts CDMA, TDMA and GSM transmission.

A GSM disruptor is a device that blocks transmission or reception of signals, usually by creating some form of interference at the same frequency ranges that cell phones use. As a result, a cell phone user will either lose the signal or experience a significant loss of signal quality.

It is manufactured to block signals in environments where cell phone activity may not be desirable, such as theaters, churches , classroom and operating rooms.

It is not hard to imagine that when you are watching a play in a theater, a telephone ring suddenly rings. Your mood must be very bad. Or when you're studying in the library. Suddenly someone in the neighborhood was talking loudly on the phone. Presumably, you really want to be quiet around. Therefore, the interference when the equipment can play its role. All you need to do is turn on the device and it will be quiet.

Disruptors GSM exist different versions. There are larger channels that can be used in a theater, library or restaurant. In addition, there are also handhelds - which often also resemble a GSM mobile phone - which makes connections in the immediate vicinity (5-20 meters) impossible. The latter can therefore be used individually in, for example, a train compartment, on the terrace or in a restaurant.

In recent years, the number of websites offering "jammers" or similar devices designed to block communications and create a "quiet zone" in vehicles, schools, theaters, restaurants, and other places has increased substantially.

In any case, in the fast pace of modern life, you will need to enjoy a moment's peace. Use a disruptor device when you are upset about the phone ring around you and quickly shut up those rude people.

Whether you're in a library, a restaurant, a movie theater, just turn on the jamming device and you'll be quiet, you can enjoy the quiet time.
