The primary objective of NIST's Public Safety Communications Research program is "to lead the development of wireless telecommunications and information technology standards, profiles, and guidelines for interoperability, and information sharing, among criminal justice (CJ) and public safety (PS) agencies at state, local, and federal levels. To achieve this it will be necessary to focus on enabling technologies and open architecture standards so that interoperability approaches can be designed and implemented. Proposed techniques and standardized configurations will be verified and validated through simulations and laboratory testing. While standards are being developed, other interim interoperability solutions will be investigated. As a secondary goal, this project will conduct technical evaluations of current and emerging technologies aimed at providing immediate assistance to CJ and PS agencies."
