Toronto Pearson is located in Mississauga, west of Toronto, in Ontario, Canada. It is Canada's largest airport and the sixth-most-connected airport in the world. "As the first airport in the world to test HEXWAVE, we see the potential benefits of utilizing this innovative solution as part of our broader airport security program following further testing and evaluation," said Dwayne MacIntosh, Director, Corporate Safety and Security, GTAA. "We were impressed with the HEXWAVE's seamless screening during beta testing and look forward to working with Liberty Defense on the enhanced detection the HEXWAVE would bring to the airport." HEXWAVE uses millimeter wave, advanced 3D imaging, and AI to detect all types of concealed metallic and non-metallic weapons and other prohibited items – without having to divest common items.

In 2014, scientists at MIT began working to develop an artificial intelligence-powered security system. Atlanta-based company Liberty Defense licensed that technology, called Hexwave, and is now making it commercially available for sports stadiums and other venues. Hexwave uses AI to search for potentially dangerous metallic and non-metallic objects. The system uses radar to scan an individual, then creates a digital 3D image from which it can determine whether the person is carrying a possible threat such as a weapon or a bottle of alcohol. The entire scanning and decision process takes less than 0.2 seconds, reducing the amount of time that is usually taken for fans to file through security scanners when entering sports stadiums.

Cruise passengers traveling out of Port Tampa Bay next spring could play a role in the testing of a new weapons detection system designed to improve safety in public places. Liberty Defense Holdings created HEXWAVE, which uses low-power, radar imaging and artificial intelligence to detect and identify weapons. The company has been developing the technology since 2018 and is ready to test it in 11 locations nationwide, CEO Bill Riker said. Similar to a metal detector, the system requires people to walk through portals one at a time as they are scanned. But unlike their more common counterpart, these scanners can detect both metal and non-metal items and use artificial intelligence to identify almost instantly what the item is and where it's located.

Canada's busiest airport will soon be using artificial intelligence-powered technology to detect weapons. The operator of Toronto's Pearson International Airport says it has agreed to test the new system developed at an Ivy League American university and marketed by a B.C. company. Vancouver-based Liberty Defense Holdings Ltd. says the technology, known as Hexwave, can detect both metallic and non-metallic weapons ranging from guns and knives to explosives. It operates by capturing radar images, then using artificial intelligence to analyze those images for signs of a weapon concealed in bags or under clothing. Liberty says the technology is not able to recognize facial features and therefore does not pose a privacy risk, a position experts in the field view with some skepticism.
