We know that today’s smartphones are equipped with a navigation system for GPS location, so the location of mobile phones is relatively easy. Since each cell phone has its own identification number, the location changeover of the cell phone takes place faster when transferring from one location to another. Of course, this can be done faster with a dedicated GPS and with a clearer and more precise location.
However, these signals can be easily blocked or overlaid. In this case we need jammers, so-called cell phone jammer or cell phone interceptors. These jammers only interfere with the signals above and do not affect other devices in the area. The jammer sends the same radio wave and suppresses it with a signal to ensure that the cell phone can no longer make contact with the radio cell and therefore cannot receive SMS e-mail or telephone notification.
This type of equipment is small, only ten feet tall, and conveniently stuck in a pocket. In some cases, e.g. B. in a cinema or in a reception room, cell phone calls can cause interference. Even in some of the stricter military bases, cell phone calls are prohibited. Therefore, jammers for cell phones can be placed in prisons to prevent prisoners from using smuggled phones by blocking radio waves.
When using cell phone jammers, we have to pay attention to the area of application and the type of use. Do not use some illegal activities as they also pose security risks if they are not operated properly. They will hinder emergency calls. Different styles and different frequency bands are offered here. Cell phone jammer, the price is between ten and one hundred euros.
In Germany, government agencies can carry out a number of projects, such as the use of jamming equipment in prisons mentioned above to block prisoners’ signals using cell phones. In France, jammers are also common in public places such as theaters and cinemas. Many people agree to use cell phone jammers. You have a good reason: when the mobile phone calls the atmosphere that interferes with performance, it is very annoying. Installing a public phone in the cinema can effectively prevent someone from having a heart attack in the cinema. Attacks, and because the phone signal is poor, the ambulance cannot be called immediately,
