Drone threats are increasing every year and security officials take it seriously
In recent years, drone threats have become increasingly apparent to many security agencies. Today, drones are used by terrorists and criminals for a number of different activities, including dropping small bombs on enemy forces in Syria and Iraq. The same drone is often used for reconnaissance and illegal smuggling of contraband into prisons.
Basically, a drone jammer creates an envelope of obstruction that surrounds the drone. Specifically, the system interferes with the drone's downlink signal to the drone operator and interferes with the signal from GPS satellites.
I also want to ban mobile phones from being brought in by the rules, which can be wrong given that students need to be informed of family needs and internet access information.

Lee also acknowledged that the notice was primarily intended for public places, but did not clarify the regulation that it could be installed in public places, and the school has also applied to the watchdog by the trust. However, no department can approve it.
"I support the school's approach and strongly hope that the school will take steps to tightly control the student's mobile phone," he said in Dongguan. Reporters interviewed parents in junior high and high school and learned that parents almost raised their hands to approve mobile phone jammers on school installation screens.
For one thing, it turns out that for most of the 16 years, we haven't really done that aggressive electronic warfare. When Bacon flew over Iraq, the overwhelming focus was on one mission: the interference of a radio-controlled roadside bomb (RCIEDS).
The Army does not have any of the standard offensive signal jammer, but some are under development and ad hoc kits are rushing to Europe. The Air Force has an EC-130H compass call, which is a large, slow target derived from a C-130 turboprop freighter, and the aircraft is worn.
