More commonly used Wi-Fi technology could be used to locate weapons and explosives found in public places, according to a research led by Rutgers University in New Jersey, USA.
As the BBC says, researchers claim that wireless signals can penetrate bags to be used for dimensional measurements of metallic objects or the volume of liquids. Initial tests have shown that the system they developed has a precision of 95% and could be used as a low-cost alternative to airport security.
For testing purposes, 15 types of items and six types of bags were tested. Wi-fi had a 99% success rate for identifying dangerous objects, 98% for metal objects and 95% for liquids. When these items were hidden in bags, the precision rate fell to 90%.
The system includes a Wi-fi device with two or three antennas and can be integrated into existing Wi-Fi networks. What it does is to analyze what happens when signals penetrate and reflect on objects and materials. It is estimated that it could be used in museums, stadiums, theme parks, schools and other places where it is thought that there may be a risk – at a particularly low cost compared to the existing infrastructure at airports.
The research was also attended by engineers at the Indiana University-Purdue University Indianapolis and Binghamton University.
