This page provides a summary of the testing and evaluation conducted at NIST on Ultra-Wideband (UWB) location systems for first responders.

The problem we are facing is how to interconnect a wide variety of heterogeneous and un-interoperable networks including wired and wireless networks in order to provide users with ubiquitous connectivity and the ability to roam seamlessly and securely across networks of different types. Our long-term goals are to bridge the technological and measurement gaps between stovepipe and heterogeneous network technologies in order to allow for better interconnectivity, seamless interoperability, and better support for network connectivity and mobility services.

To provide telecommunications designers working in public safety communications with channel propagation models to use in simulation and testing.
