Certain commercial entities, equipment, or materials may be identified in this document in order to describe an experimental procedure or concept adequately. Such identification is not intended to imply recommendation or endorsement by NIST, nor is it intended to imply that the entities, materials, or equipment are necessarily the best available for the purpose. There may be references in this publication to other publications currently under development by NIST in accordance with its assigned statutory responsibilities. The information in this publication, including concepts and methodologies, may be used by federal agencies even before the completion of such companion publications. Thus, until each publication is completed, current requirements, guidelines, and procedures, where they exist, remain operative. For planning and transition purposes, federal agencies may wish to closely follow the development of these new publications by NIST. Organizations are encouraged to review all draft publications during public comment periods and provide feedback to NIST. Many NIST cybersecurity publications, other than the ones noted above, are available at http://csrc.nist.gov/publications.

The public safety community is in the process of transitioning from the use of land mobile radios (LMR) to a technology ecosystem including a variety of broadband data sharing platforms. Successful deployment and adoption of new communication technology relies on efficient and effective user interfaces based on a clear understanding of first responder needs, requirements and contexts of use. This project employs a two-phased data collection approach for an in-depth look at the population of first responders, along with their work environment, their tasks, and their communication needs. This report documents the data collection of Phase 1 and the resulting data analysis. Phase 1, the qualitative component, focuses on interviews with approximately 200 first responders (law enforcement, fire fighters, emergency medical services, communications/dispatch) across the country. The results include user needs and requirements expressed by first responders. These needs and requirements have been organized into five categories of technology opportunities. Further analysis identified six user-centered design guidelines for technology development. Finally, the importance the role of trust plays in first responders' adoption and use of communication technology is presented.
