Wireless emergency safety equipment could save lives—if signals are transmitted reliably. But few performance standards exist. Now, tests at the National Institute of Standards and Technology (NIST) are helping to ensure that alarm beacons for firefighters and other emergency responders will operate reliably in the presence of other wireless devices.
NIST is providing technical support for industry consensus standards by developing test methods to evaluate how well these devices work under realistic conditions. The latest NIST study focused on interference between Personal Alert Safety Systems (PASS) with wireless alarm capability, and radio-frequency identification (RFID) systems. The methods developed in the study can test interference in other wireless devices such as radios, hands-free cell phone headsets, local area networks, and urban search and rescue robots. | Read the full NIST "Tech Beat" story
