Project 25 has been a First Responder driven Standard since its inception 32 years ago. Learn about the current top priorities for the evolution of P25 from the P25 User Needs Working Group (UNWG) and the P25 Steering Committee Chair. Get an Update for P25 Standards recently completed and new Standards in development including LMR interworking with LTE and Mission-Critical PTT. Explore P25 Inter-System Interface (ISSI) capabilities and best practices for multi-agency interoperability through roaming and sharing across stand-alone P25 Systems region-wide, and state-wide.

Project 25 technology is evolving to expand interoperability, add features, and offer improved security for First Responders. See what's new in 2024 including: New P25 Link Layer Security Standards (Cyber Security for P25 Control Channels and Unit IDs), A new "GPS location on every PTT" Standard for P25 subscriber units and a new Multi-vendor "User ID alias" capability to share the First Responder's user-name for each unit across multiple systems and talk groups.

Strong interest in Communications Security and Encryption is growing. Review the new P25 Link Layer Encryption Standards, P25 User Authentication Standards, and improved, interoperable, AES Key Management for Over the Air voice and data security.
