However, as a rule, portable modifications are purchased, which are convenient to carry with you or take in the car. Their radius of action is 8 meters. The radio frequencies with which GSM format devices operate are jammed.
Speaking of modern technologies, it is necessary to distinguish the principle of operation of jammers into two halves. Previously, they were used for their intended purpose in public places, for example, in cinemas, where it is important to maintain silence during a session. But today the purpose of such devices has changed 180 degrees, as mobile devices are now used as a means of surveillance and eavesdropping.
And what does abroad have to do with it?
Over the past year, everyone has heard stories about how foreign governments monitor ordinary citizens using modern means of communication. Since intelligence services have almost unlimited resources, they can easily take over your device. And although a cell phone jammer in this case cannot protect against all risks, it will not be superfluous.
Such devices are especially useful for businessmen who travel abroad for their financial affairs. Here, attackers have a huge space for maneuver: from banal eavesdropping and subsequent blackmail to theft of important data. Relatively new are jammers for Wi-Fi. In this range, there is also a danger for mobile phones, especially new ones.
On the other hand, a cell phone jammer will come in handy as a shield against attackers trying to steal your confidential data: logins and passwords from websites on the Internet, correspondence, phone book, and generally everything stored on a mobile device (not necessarily a phone). Moreover, today's criminals use zombie devices to transfer money from the phone itself to their accounts, and in the worst case, from a bank card.
There are also banal scammers who send links to phishing sites, letters with requests, or even groundless threats to the potential victim's phone, playing on the recipient's feelings.
If you do not want to face the problems described below, try to protect yourself from encroachments on privacy and just comfort. It is the cell phone jammer that will become a formidable weapon in your hands.
