The signal is easily blocked or superimposed. In this case, we need to use jammers, so-called cell phone jammer or cell phone blocker. These jammers will only interfere with these signals and will not affect other devices in the area. The jammer sends the same radio wave and suppresses it with a signal to ensure that the mobile phone can no longer establish contact with the radio cell and therefore cannot receive any SMS mail or phone notifications.
When using mobile phone jammers, we must pay attention to the application field and the type of use. Avoid using some illegal activities, because they can also bring security risks if they are not handled properly. They will interfere with emergency calls. Different styles and different frequency bands are provided here. Mobile jammers cost between ten and one hundred euros.
When a drone flies over your property and harass you, for example, B. If you take a photo, even if you think that someone else is joking with you, you may not know who is tampering with the drone. If you don’t want to face this risk, you can use jammer drones, which are currently the most effective way to control privacy with drones.
Using drone jammer, you can effectively protect yourself from spying by drones or multi-rotor aircraft. Can you use the drone to jam the weapon and shoot down the drone? This is a very effective way to defend against drones. There are no clear laws in EU countries that allow other drones to fly over your private property or garden without permission. This seriously violated the private property of individuals.
The development of jammer technology is as fast as the development of drones. In the case of jammer operation, in most cases, the device will fly back to the pilot or hover in the air or even land without destroying the drone.
This includes installing high power jammer in the prison, cutting off all cellular signals within a certain range of the prison, and blocking any unknown communications, thereby disconnecting all connections between the prison and the outside world.
