Large Range Disruptor for CDMA/GSM

A gsm jammer is a device that emits signals in the same frequency range that cellphones use, effectively blocking their transmissions by creating strong interference. In Europe those frequencies are gsm 900MHZ and gsm 1900 MHz.

Cell phone jammer are radio broadcasting devices that block cellular phone calls within a radius of 30 to 160 feet.

Someone using a cellphone in the range of a jammer will lose signal, but have no way of knowing a jammer was the reason. The phone will simply indicate poor reception strength.

Cell phone jammers come in a variety of sizes, can affect large or small radiuses, and can target a variety of cell phone bands (frequencies used to communicate with towers). Jammers either disrupt phone-to-tower frequencies or tower-to-phone frequencies. The latter is typically more effective.

The right frequencies to choose depend on the devices to be jammed. In order to prevent a cell phone from being able to get reception, one should have the use of a cell phone jammer, which blocks cellular frequencies, hence GSM, 2G, 3G and 4G LTE for the latest Smartphones. In case you don´t know the frequencies on which the mobile phone transmits, the only thing left for you to do is to find out its technical specifications on the internet or somewhere else.

Of course, the choice of a suitable GSM jamming device also needs to take into account the range of interference and portability. A jamming device that works for you will make you feel more comfortable using it. You can maximize the use of jamming devices without affecting others.
