Low-Cost NIST Demo Links Public Safety Radios to Broadband Wireless Network

Credit: N. Hanacek/NIST Engineers at the National Institute of Standards and Technology (NIST) have built a low-cost computer system that connects older public safety radios with the latest wireless communications networks, showing how first responders might easily take advantage of broadband technology offering voice, text, instant messages, video and data capabilities. NIST’s prototype system could help overcome a major barrier to upgrading public safety communications. Many of the 4.6 million U.S. public safety personnel still use traditional analog radios, due to the high cost of switching to digital cellphones and these systems’ slow incorporation of older “push to talk” features that are both familiar and critical to first responders.
