The Project 25 Technology Interest Group (PTIG) has published an April 2018 Update to the P25 Steering Committee By-laws as an information resource for the P25 User Community.

Project 25 is a unique user-driven process created to establish current and emerging wireless communications standards that meet the requirements of the public safety community. In this standards development process, Project 25 is directly involved with users and manufacturers. It also involved the development of a partnership with the TIA. Using the TIA Engineering Manual, TIA may develop a suite of technical standards, telecommunications system bulletins and technical white papers that enable the development, manufacture and operation of interoperable Project 25 communications systems and system components that satisfy the Project 25 adopted requirements.

Subsequent to signing the MOU, in 1993 APCO officially changed its name to the Association of Public-Safety Communications Officials-International, Inc. In 2007, NASTD officially changed its name to the National Association of State Technology Directors.
The formal relationship with TIA was established through the execution of a MOU that outlines the responsibilities and obligations of both parties and the framework that TIA and Project 25 agreed to work within.

A key element of the MOU is the clear understanding that the Project 25 Steering Committee may choose to select any standards proposal, telecommunications system bulletin, or white paper as a P25 Standard, but a TIA/Project 25 standard can only be created in accordance with the TIA-approved Engineering Manual, policies, and rules and regulations that coincide with the requirements of the American National Standards Institute (ANSI) process for Standards Development Organizations (SDO).

The Project 25 Standards Process is based on users determining the functionality and critical interfaces that require standardization to ensure interoperability among Project 25 system components produced by any manufacturer. While it is a user driven process, it is done in cooperation with industry to ensure both the expectations and deliverables can be achieved. These functionalities and interface requirements are documented in the Project 25 Statement of Requirements (P25 SOR). The P25 SOR is in turn approved and maintained by the P25 Steering Committee. Formal standard documents are developed, balloted, published, and maintained by the TR-8 Mobile and Personal Private Radio Standards Committee of the Telecommunications Industry Association (TIA).

Summary taken from the Mission Critical Article:

"Motorola contracted the CAP-recognized personnel from Compliance Testing to perform tests in its Motorola Schaumburg labs April 30 – June 1 and to create the detailed test reports (DTRs) that all participants will use to create their respective CAP documents, said Andy Davis, Motorola’s P25 standards manager."

"Motorola, JVCKENWOOD, Harris, EF Johnson, BK Technologies, Tait, Icom America and GME are confirmed to participate. Testing at the event includes P25 Phase 2 requirements and standards for the Common Air Interface (CAI), and the participants will test FDMA, TDMA and inter-wide-area communications network (WACN) functionality."

PTIG Publishes Three New Project 25 Panel Presentations for 2018:

P25 Foundations, P25 User Experience, and a P25 Security Update.

The Project 25 Technology Interest Group is now offering a comprehensive P25 Update through the Power Point presentations presented at the recent IWCE conference in Orlando. The Three Power Point presentations cover:

• P25 Foundations: The latest update to the P25 Standards, and their applications
• P25 User Experience: A series of new P25 case studies from a diverse group of P25 System administrators and directors.
• P25 Security Update: The latest on P25 Security including an overview to the new P25 Link Layer Encryption Standard, P25 Authentication and P25 Key Management improvements.

Copies of the presentations can be downloaded from the PTIG Website:  http://www.Project25.org

• PTIG P25 Conference Presentations
• PTIG P25 System Case Studies

Summaries of the Presentations are below:

P25 Foundations

This PPT delivers information useful to those seeking a deeper understanding and updated awareness of the established P25 standards, the matching equipment capabilities, and the continued evolution of system technologies and interfaces. Completed P25 Standards, recently published updates, and future P25 work priorities are covered. Content includes: A Basic P25 Overview of the P25 Interfaces including: Trunking and Conventional systems Phase 1 and Phase 2 systems, and Wireline interfaces including the systems (ISSI), console (CSSI)and fixed station (FSI). In addition the latest CAP testing Update is included. New topics for 2018 include: Improved Encryption Key Management standards, TDMA Trunking Control Channel, P25 Link Layer Encryption, ISSI and CSSI interoperability, and The P25 Value Proposition. The PPT also includes topics on the use of P25 for Emergency Communications, how to use P25 to develop an RFP, and an update on the P25 Product and Services available in the market.
