The dream of wireless networks fast enough to power fully immersive VR and fleets of autonomous vehicles has always run into one humiliating obstacle: walls. High-frequency signals—especially in the sub-terahertz spectrum—carry enormous bandwidth, but they collapse the moment a chair, a bookcase, or a human body gets in the way.
Princeton engineers just rewrote the rules. Their system doesn’t bounce signals around obstacles with clunky reflectors—it bends the signal itself. Think curveball physics applied to Wi-Fi.
