Mobile phones were originally invented to talk to someone when needed. But over time, things have changed. Nowadays, mobile phones are not only phones, but also computers, portable entertainment devices, Internet terminals, wallets, GPS navigation items, movie theaters, etc. Now you can see that everyone carries a mobile phone with them every time they go everywhere, sit, walk, eat, shop, and party. So, have you noticed the problem now? When praying in the church, someone said loudly, would there be a problem with the phone? Is there a problem with the phone ringing when watching a movie in the cinema? Or, what if someone yelled to his cell phone in the library? Yes, we can now agree that misuse of mobile phones can cause serious problems. We need to find a way to stop using mobile phones in certain places. For this, we need cell phone jammer.
In the past few years, various types of jammers have been provided on many websites. They are different in size, shape, weight, power, interference distance and frequency range. If you want to use jammers on specific occasions, indoor blackout devices will be your ideal choice. Cell phone jammers designed for indoor use are very effective in blocking cell phone signals. When someone’s mobile phone bothers you, just turn on the jammer and the phone will stop working within a few seconds. In addition, you can also choose a jammer, which can cut different frequency bands: CDMA: 850-960 MHz, GSM: 1805-1880 MHz, GSM: 1920-1990 MHz and 3G: 2110-2170 MHz, which is very convenient. The interference radius of mobile jammers is between 5 and 50 meters. All phones in this range will stop working: their owners will not be able to make/receive calls and send/receive messages. In addition, mobile phone jammers are powerful because they are equipped with omnidirectional antennas that can block signals from different directions. We can guarantee that after turning on the jammer, you will not be disturbed in an environment without mobile phone interference.
