Rather than jamming a drone, the Army Cyber Institute at West Point built an antenna-and-computer rifle that fed information into an open channel of an unlocked Parrot drone. This allowed the cyber rifle to send an override code to the Parrot drone, crashing it, without violating FCC and FAA rules on signal jammer. At a training exercise this summer, West Point cadets encountered a drone on a simulated raid, and had to use the cyber-rifle to knock it out of the sky. The consequence, for a team that failed to plan around the drone, was an artillery strike that took out the entire machine gun section of the platoon.
So worst case you would have an old cellfone with a small circuit board sandwiched to it externally which would have a PIC or other microntroller on it.Or even better, invest some time into deciphering how to download a new firmware program into the phone’s main CPU. If you can do that, it would be simple enough to write a small program to do nothing more than send random noise, at full power, on the correct frequency.
So, sometimes we need to rely on some means to maintain their own enjoyment of the right quiet. For example, signal jammers.Desktop wifi jammer usually can block all cellphone, can be a good guarantee of the surrounding quiet. At the same time, desktop jammers also have a large jamming range, jamming signal stability characteristics. For the user, this is a very good feature.
Also, you’ll need a good RF-testing equipment, an aluminium box, ultra-high frequency connectors which can be found in old phones, 9-volt battery, and a voltage regulator. RF input (which is this port of the mixer) connects to the first 800MHz cell phone antenna, and the RF output is sent to the mini-circuit amplifier. This amplifier increases the output power for 15-16dbm. The amplified signal is then sent to the second cell phone antenna.
With the popularization of smartphones, more and more children are beginning to indulge in mobile sms and various kinds of social. This is a national and international problem. Kids use their gadget crutches just as much as adults do. And there seems little you can do to stop them.Chinese and Indian schools use jammers to stop cheaters. Mexico allows jammers in churches and hospitals. And Pakistan allows jamming in banks and libraries.
