Did the White House Use Drone Killing Technology?

At about 3 a.m. on Monday 26th January, a small quadcopter drone, or unmanned aerial vehicle, crashed on the White House lawn. White House officials said that the drone, by itself, was unarmed and didn't represent a threat. Authorities quickly located the owner, a government employee, who has managed (so far at least) to convince the Secret Service that he made an innocent mistake flying his drone outside of the White House in the wee hours of the morning.

The White House won't comment on whether or not they took any special steps to bring down the small UAV. But the White House may have employed the same anti-drone technology that the military is trying to perfect to protect ships and planes from future drone swarms. There are plenty of ways to knock a drone out of the sky, everything from surface to air missiles to hunter-killer robots to, yes, lasers. But for a cheap off-the-shelf drones operating off a simple radio or Wi-Fi signal, the best method is simple jamming.

For the military, signal jamming is an increasingly important component of electromagnetic warfare, or EW. It's an area of growing concern as the electromagnetic spectrum, an area where the United States once enjoyed sole dominance, is becoming increasingly crowded.
