PTIG P25 Update for IACP Communications and Technology Committee October 2018

The Department of Homeland Security Office of Emergency Communications (OEC) and the Project 25 (P25) Steering Committee sponsored a P25 Executive Summit in Portland, Oregon, May 16 and 17, 2018. Leaders from P25 public safety user agencies at all levels of government and the P25 vendor community were invited to address P25 Land Mobile Radio (LMR) user concerns. Topics included P25 LMR interoperability successes and challenges and opportunities to collaborate to ensure the future sustainment of critical LMR capabilities.
This two day event included an opportunity for the user community to share concerns and lessons learned, and identify topics on specific agenda items to discuss with manufacturers as the Summit progressed. On the second day, both users and vendors met to address key P25 issues and concerns from both the user and manufacturer perspectives and develop collaborative approaches to effectively address the improving and sustaining LMR capabilities.
The primary goals and objectives of the Summit were to provide participants with a better understanding of how the P25 user community and the vendor community can develop an enhanced dialog outside of marketing pressures to resolve the challenges that face public safety, specifically to:
 Address how disparate systems and manufacturers’ interpretations of the standards can negatively impact interoperability
 Develop a process that will lead to an environment where all P25 compliant equipment, regardless of make or model, are interoperable upon delivery
 Articulate the importance of interoperability and critical activities to improve user-to-user communications and user-to-vendor interactions
 Obtain commitments from participants to support identified actions
