The presence of jammers is no accident

Why do people need signal jammer?

There is a little control in the schools in the UK, but only to lock your phone to their WiFi. Only school stuff is allowed to be searched up , sites on educational things and student/teacher email etc. Although if you don’t opt for the school WiFi network when it flashes up on your phone first time you try using your internet there, just ignore it and use your cellular data. Although most kids I know don’t have any most of the time. Hope the are trying to find a way of blocking the waves so kids can’t use their phones during lessons at least, just so distracting for everyone around the idiot who can’t live without social media.

To build the school to cell phone jammer, it would cost so much money that the school would be deep in debt. The school could also use a jammer to jam the phone signals.

Almost everyone makes use of the mobile phones everywhere whether it is a theatre, educational institute, café, restaurant, office or any other place. People nowadays spend their most of time on mobile phones rather than spending a good time with their families or focusing on their organizational goals. Though mobile phones may help you in a number of ways, it has distracted many lives as well. This is where the cell phone network gps jammer comes into the play. Jamming refers to the act of obstructing something and therefore mobile jamming refers to obstructing the network signals to reach your mobile phone and thereby denying the access to the internet, sending text messages or phone calls.

These "drone rifles" typically target GPS first as it is easy to jam. If that doesn't work they will start jamming in the typical frequency range of commercial drones to break the link of the controller. On most off the shelf drones if you break either GPS or controller link it will go into "return to home" mode or will slowly hover to the ground and land.

It doesn’t appear that the drone was hit by a projectile or laser in its descent (though evidence of such would certainly change this analysis). Barring a physical projectile, the known non-kinetic methods for stopping a drone are threefold: radio frequency (RF) jamming, global navigation satellite system (GNSS) jamming, and spoofing. With RF gsm jammer, the link between the drone and its operator is severed, usually causing the drone to descend or return to home. With GNSS, the drone’s link to satellite navigation is lost, and the drone then usually hovers in place, lands, or returns home. With spoofing, the attacker feeds the drone new information to take control of its flight.

None of these methods require any bright flashing lights, which could easily be a cosmetic feature of the counter-drone system. Given the drone’s sudden spiraling descent in the released video, it’s likeliest that the system featured is a radio-frequency jammer. It is also likely, given the system’s employment on the side of the Russian-backed separatists, that the system is another Russian-made electronic warfare weapon, fielded on the front lines of a proxy war as much for battlefield impact as it is for research and test purposes.

The jammer generally causes a drone to either perform a vertical controlled landing or return to its starting point – the default actions of most drones that lose communication – “assisting an investigation to identify the pilot,” the company said.

The U.S. Army wants drone-mounted signal jammers now to dominate future electronic warfare and is switching to a little-understood and lightly regulated contracting method to get them.
