Bend the beam like Beckham to defeat anti-jamming tech

Source summary: Wireless jamming attacks are on the rise. Rice University researchers have shown how self-curving radio beams can make a jammer appear to be somewhere it isn't, potentially undermining some anti-jamming defenses. Jamming relies on flooding a wireless receiver with noise that denies service. Some modern receivers identify and block jamming attempts using direction-of-arrival (DoA) estimation technology that pinpoints the jammer's direction and directs an array null that blocks signals emanating …
