That even state intelligence services have had difficulty in determining the source of the gps jammer and whether or not it was deliberate, highlights how effective these tactics can be even during an uneasy peace. With electronic and cyber assaults, Russia has found an effective way to disrupt the military and government activities of its regional opponents while maintaining a surprising amount of plausible deniability.
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. Ideally, the safest and most ideal preventive action would be to stop the drone from ever entering the stadium. A simple way to do this would be to direct a beam of RF energy onto the drone that would disrupt the communications to the operator. This can be done with the kind of Wi-Fi RF jammer that is sold to military and government groups. These Wi-Fi jammers will stop most, if not all, hobbyist, commercial and unsophisticated terrorist drones and cause them to return to where they launched with very little chance of doing much more than interfering with people’s Wi-Fi connection in the very near vicinity.
The VCO is certainly the key component in a mobile phone jamming process. It’s a tad four-terminal gadget (Vcc, RF Output, Voltage Tune, and Ground) which translates into the preferred low-level RF output signal with a nominal degree of hassle.
Propelled by the military’s experience with roadside bombs in Iraq and Afghanistan, jamming technology has evolved to counter bombs triggered by cellphones, garage openers, remote controls for toy cars or other devices that emit radio signals. Federal authorities rank improvised bombs, which are cheap and adaptable, as one of the greatest terrorist threats to the West.
