Wi-Fi Can Detect Weapons at Security Checkpoints

This article examines Wi-Fi Can Detect Weapons at Security Checkpoints. It presents the main facts, practical implications, and key points in a clearer, easier-to-follow format.

Understanding Wi-Fi Can Detect Weapons at Security Checkpoints

Wi-Fi was able to see through the wall, so it was possible to think of using technology to see through objects. In the future, it can help protect security by checking bags, luggage without direct infringement, as well as speed up testing compared to manual methods.

Researchers at Rutgers University recently pointed out that conventional Wi-Fi can be used to check bags and estimate the size of things like weapons, laptops, batteries, and the ability to identify them. Moreover, it can identify liquid volumes such as acids, alcohol and other chemicals used to make explosives.

This technology works by separating wireless interference caused by objects, from shapes to their materials. The device only needs 2 to 3 antennas and can use the existing Wi-Fi network.

The researchers experimented with 15 types of objects and 6 types of bags. Accordingly, their Wi-Fi system describes 99% of dangerous objects, 98% of metallic objects and 95% of liquids. Accuracy drops to about 90% when objects in the bag are closed.

Wi-Fi can help people save more on security checks.

Professor Yingying Chen, co-author of the award-winning research report at the IEEE Conference on Communications and Network Security event, said that in a large public area, it is difficult to establish an expensive inspection system. like at the airport, and that they are trying to create a way to reduce the burden on people at security checkpoints.
