We built a coalition of emergency responders and communications manufacturers to form a Compliance Assessment Program (CAP) that tests equipment for P25 compliance.

Features

✔ Public Safety 700-MHz Demonstration Network Study Items

Participate in the study item groups formed for the Public Safety 700-MHz Demonstration Network PSCR is implementing to provide manufacturers a location (view a Google Earth flyover) for early deployment and evaluation of their systems in a multi-vendor environment.

✔ Modified Rhyme Test — A PSCR study to understand how background noise (listen to samples) affects fire fighter LMR voice communications.

✔ PSCR is providing public safety video application research samples to the CDVL, which PSCR helped to launch. Margaret H. Pinson leads the PSCR program’s CDVL efforts. See her ACM SIGMM interview, “An Interview with Video Quality Experts.”

The PSCR program provides research, development, testing, and evaluation to foster nationwide first-responder communications interoperability. The PSCR program provides insight to wireline and wireless standards committees developing standards for voice, data, image, and video communications.

Housed within the U.S. Department of Commerce Labs in Boulder, Colorado, the PSCR program is a joint effort between:

NIST/OLES

NTIA/ITS

The PSCR program has earned five U.S. Department of Commerce Medal Awards (two Gold, one Silver, two Bronze) for the performance of applied engineering and research to advance public safety communications interoperability. The PSCR program’s engineering and research is sponsored by:

Department of Homeland Security
Office for Interoperability and Compatibility

National Telecommunications & Information Administration
First Responder Network Authority
