WEBINAR Overview:

Project 25 (P25) remains critically important to public safety users. With over 2800 systems on the air and 42 State-wide Networks, its continued evolution with new standards, capabilities and applications will be relevant, even as FirstNet and other public safety broadband networks roll out. In this WEBINAR, hear how P25 is adapting and interworking to meet the changing technology marketplace. Hear what’s new…..Hear what is coming…..Hear how it will help you.

Stephen Nichols – Moderator, Executive Director, Project 25 Technology Interest Group (PTIG)

This session will offer a view of what has recently been completed and what is ahead for the P25 Suite of Standards. Details of what new capabilities and applications will be available this year and, in the future will be shared. The key benefits of Project 25 as a Public Safety Grade communications technology will be defined. The Project 25 Technology Interest Group (PTIG) full library of P25 resources and whitepapers including P25 System lists and P25 product and services suppliers will be included.

Robin Grier - President, Catalyst Communications Technologies

Many are asking “What Interworking will be available between my P25 system and the new LTE MCPTT Systems? To that end, a view of future Interworking Standards between P25 LMR systems and Public Safety LTE Systems will be covered by Catalyst.

David Adams – Director Business Development, PCTEL, Inc.

In addition, many are asking “How can I test P25 radio signals and coverage inside buildings and structures. The latest P25 Testing technology applications will be offered by PCTEL.

Robert Kwapisz, P.Eng - Product Manager LMR Solutions, Zetron 

The P25 Digital Fixed Station Interface (DFSI) can maximize integration with data-driven technologies like video, MCPTT, and AVL over LTE networks. A description of what Quality of Service means in the context of P25 and LTE and discuss what performance metrics may be most important will be covered by Zetron.

The Project 25 Technology Interest Group is pleased to publish links to two new P25 Videos: Basics of P25 and Encryption in 3 Minutes. The Videos are from the P25 Steering Committee produced by DHS CISA, P25 Support Team

CISA Video: Basics of P25

By: Jim Downes, P25 Steering Committee Chairman

One only has to talk with public safety personnel who routinely use P25 to get a real sense of its value to communities nationwide. A new five-and-a-half minute CISA video—” Basics of P25”—does just that. Through interviews with responders, communications managers and engineers, emergency operations managers, and Statewide Interoperability Coordinators (SWICs) from across the Nation, the video covers:

  • P25’s role in public safety
  • Its value in both daily operations and emergencies involving mutual aid partners and outside agencies
  • Its advantages for enhancing personnel safety and operational efficiency
  • Cost savings it offers communities, and
  • Practical recommendations for planning and implementing a P25 radio system.

For agencies considering a P25 system, the video offers a clear, practical overview of the technology’s ever-increasing role in law enforcement, fire, and emergency medical organizations and a foundation for exploring P25 in greater detail through CISA’s and SAFECOM’s library of P25 documents.


CISA Video: Encryption in Three Minutes

Drawn from interviews with emergency communications practitioners nationwide, “Encryption in Three Minutes” presents an overview of LMR and P25 encryption in public safety operations. The video outlines encryption’s role in protecting sensitive tactical and operational communications as well as the personal identifiable information and medical status of civilian patients during emergencies. Discussion focuses on implementing a practical, reliable encryption system while preserving interoperability with mutual aid partners and outside agencies. Special attention is given to selecting the most secure encryption algorithm. It is an ideal brief overview of LMR encryption aimed at community leaders and public safety administrators, officials, and responders.
