P25 Committee Launches Working Group for Radio Programming Compatibility
Monday, February 27, 2017 | Comments

The Telecommunications Industry Association (TIA) announced that its TR-8 Mobile and Personal Private Radio Standards Committee launched several new initiatives, including the development of new working groups, and elected new leaders. The committee develops the Project 25 (P25) standards.

At the recent TIA TR-8 meeting, three engineering committees initiated new technical work and launched new working groups.

TR-8 created a new working group addressing radio programming compatibility requirements. At the request of the National Public Safety Telecommunications Councils (NPSTC), TR-8 members agreed to begin development of a draft schema that will allow the import of certain radio programming parameters from a manufacturer's code plug programming software and allow the export of these parameters into another manufacturer's code plug programming software.

The TR-8.5.1 working group was launched to work on a revision to the P25 Location Services Overview Bulletin TSB-102.BAJA-A. The revision is based on comments that resulted from a review of the published document.

The TR-8.25.1 working group is working on a revision to add tests that are recommended for the Console Subsystem Interface (CSSI) application of the Inter RF Subsystem Interface (ISSI). Once approved, these recommendations will be given to the DHS Office for Interoperability and Compatibility (OIC) P25 Compliance Assessment Program (CAP) advisory panel. The panel will consider incorporating them as they draft a Compliance Assessment Bulletin (CAB) for CSSI testing. 

Committee participants include staff from Motorola Solutions, Harris, Relm Wireless, Airbus DS Communications, the U.S. Department of Homeland Security (DHS) E.F. Johnson Technologies and others.

“TR-8 is led by an incredibly dedicated group of industry volunteers, and their work is having a very real and very positive impact,” said Stephanie Montgomery, TIA vice president for technology and standards. “Public safety is one of the most important areas of focus for the committee, and we are excited about the new initiatives launched at our recent meeting. Because of the critical nature of this work, we hope to expand industry participation and invite anyone with technical expertise or interest in public-safety equipment standards to contact us.”

TIA’s TR-8 committee also elected new leadership. Andy Davis, senior resource manager P25 Standards at Motorola Solutions, was re-elected as chair of the TR-8 Committee on Mobile and Personal Private Radio Standards. Davis will also serve as interim chair of the TR-8.11 Antenna Systems Committee.

Jim Eastwood, distinguished member of the technical staff at Motorola Solutions, was re-elected as chair of the TR-8.5 Committee on Signaling and Data Transmission. Eastwood was also re-elected as chair of the TR-8.15 Committee on Common Air Interface (CAI).

Robert Shapiro, independent LMR industry consultant at Shapiro Consulting Services, was elected as vice chair of the TR-8.18 Wireless Systems Compatibility – Interference and Coverage Committee, which defines terms and methodology for the modeling, simulation and empirical performance verification of LMR systems.

John Lambrou, distinguished member of the technical staff at Motorola Solutions, was re-elected as chair of the TR-8.17 Radio Frequency Exposure Committee, which establishes common terms, definitions, methods of measurements to aid interested parties in evaluating adherence to FCC guidelines concerning RF exposure. Lambrou was also re-elected as chair of the TR-8.21 LMR Intrinsic Safety Consideration Committee.

TR-8 will hold its next meeting in June in Chicago.
