Why Perimeter Fencing Defense Is Failing Against Modern Drone Warfare
By Marcus Vance
Can high-voltage anti-drone netting replace standard perimeter fencing?
No. Netting cannot support the structural demands or anti-ram vehicle crash ratings of standard perimeter walls. Netting acts purely as an overhead canopy over vulnerable assets, serving as a secondary layer rather than a standalone perimeter replacement.
Why can't private companies buy drone jammers to defend their facilities?
Federal law heavily restricts electronic warfare gear. In the United States, the FCC and FAA ban private companies from buying, testing, or operating jammers because these signals disrupt public radio bands, cellular networks, and civilian aviation navigation. Only specific federal agencies hold legal authority to jam signals on domestic soil.
What is the most effective drone defense for an unprotected facility today?
Deploying an integrated passive detection array using RF monitoring and micro-Doppler radar. While civilian facilities cannot legally down an unauthorized drone, detecting an approach 2 to 3 miles away gives security personnel enough time to shut exterior blast doors, protect personnel, preserve video evidence, and direct law enforcement straight to the operator's takeoff location.
