Bend the beam like Beckham to defeat anti-jamming tech
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.
Training-Free Object-Agnostic Jam Detection in Fulfillment Centers
arXiv:2606.00321v2 Announce Type: replace Abstract: In fulfillment centers, diverse objects move continuously from inbound to outbound operations and can become jammed due to excessive conveyor friction, incorrect orientation, or mechanical failures. Traditional jam detection approaches rely on object detection models to identify objects, followed by tracking algorithms (such as IoU overlap and Kalman filtering) to monitor motion over time. This pipeline requires thousands of manual...
Encoded Jamming Secure Communication for RIS-Assisted Systems
Announce Type: replace Abstract: This paper investigates a cooperative jamming (CJ)-aided secure wireless communication system. Conventional CJ schemes transmit Gaussian noise (GN) to improve security, which inherently degrades the legitimate receiver's performance. While encoded jamming (EJ) mitigates this interference, its superiority over GN is highly channel-dependent.
Nitric oxide overload jams plant immune signals, researchers find
Nitric oxide overload jams plant immune signals, researchers find Gaby Clark Scientific Editor Robert Egan Associate Editor A new study from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) helps explain how plants can lose track of their own disease warnings. Plants do not have blood, nerves or immune cells like people do, but they still have ways to protect themselves. When one leaf is attacked by a pathogen, the plant can send warning signals to...
Jamming-Resilient PRB Reservation for Latency-Critical O-RAN Network Slicing
Announce Type: new Abstract: Open radio access network (O-RAN) architectures enable near real-time, software-driven control of network slicing through programmable xApps deployed on the near-real-time RAN Intelligent Controller (near-RT RIC). In industrial 5G downlink systems, adversarial jamming can abruptly reduce the effective physical resource block (PRB) capacity, triggering queue buildup and persistent latency violations, particularly in the presence of low spectral efficiency cell...
Transforming Police-Car Swerving for Mitigating Isolated Stop-and-Go Traffic Waves: A Practice-Oriented Jam-Absorption Driving Strategy
arXiv:2602.10234v3 Announce Type: replace-cross Abstract: Stop-and-go traffic waves, a major form of freeway congestion, impose severe and persistent adverse impacts, including reduced traffic efficiency, increased safety risks, and elevated vehicle emissions. Among various freeway traffic management strategies, jam-absorption driving (JAD), in which a dedicated vehicle performs "slow-in" and "fast-out" maneuvers before being captured by a stop-and-go wave, has been proposed as a promising...

GPS jammed on RAF jet carrying UK defence secretary close to Russian border
An RAF jet transporting UK Defence Secretary John Healey experienced signal jamming during a three-hour flight near the Russian border. The electronic attack occurred as Healey was returning to the UK after visiting British troops in Estonia. Russia is suspected of obstructing the signal during the flight.
Tests suggest Russian satellites can jam GPS on a continental scale
Russian satellites have been identified as the cause of mysterious, seconds-long bursts of GPS interference across Europe—a rare example of human-made GPS interference coming from space. But uncertainty still hangs over whether such interference is intentional and if it could be more powerfully weaponized as GPS jamming with continental reach in the future. The discovery came from an investigation detailed in a June 2 preprint paper by Todd Humphreys and his student Zach Clements at The...
