Researchers from Rutgers University have published a study that show Wi-Fi can be used to detect weapons and bombs. The study shows Wi-Fi was able to tell the difference between dangerous and non-dangerous items 99 percent of the time. It was also very effective in the detection of liquids and metals. This technology will eventually supplement X-ray and CT scanning at airports to further improve airline safety. I believe if it speeds up security checkpoints it needs to be deployed ASAP.
According to the researchers’ paper, most dangerous objects contain metals or liquids. Those materials interfere with Wi-Fi signals in a way that researchers can detect. And the baggage a person might use to contain a bomb, weapon, or explosive device is typically made of materials — paper or fiber, often — through which Wi-Fi signals pass easily.
