Project 25 Documents & Standards Reference
Welcome
Project 25 (P25) is a partnership between the public safety communications community and industry manufacturers. The Project 25 Standard was originally developed as a suite of P25 standards, published by TIA, to enable the offering, procurement, and operation of interoperable, narrowband digital two-way wireless communications P25 products and systems that meet the mission-critical needs of public safety practitioners. The P25 standards were also intended to enable governmental and private sector organizations to implement standardized, narrowband LMR products and systems for other communication purposes.
Project 25 was established by joint efforts of:
■ The Association of Public Safety Communications
Officials International (APCO)
■ National Association of State Technology
(formerly Telecommunications) Directors (NASTD)
■ Selected Federal Agencies
■ The National Communications System (NCS).
Project 25 was set up to address the need for common digital public safety radio communications standards for First Responders and Homeland Security/Emergency Response professionals.
In 2011, the Project 25 Steering Committee and TIA established revised procedures based on their reinterpretation of the MoU such that TIA now develops and publishes generic, narrowband LMR standards that may be adopted by the Project 25 Steering Committee to become part of the Project 25 Standard. Thus, TIA now develops open standards to serve the broad LMR marketplace, but which may also be be adopted by the Project 25 Steering Committee.
The P25 DSR tracks the current state of TIA standards documents, expected to be or adopted as part of the Project 25 Standard by the Project 25 Steering Committee, to help public safety and other LMR system managers make planning and procurement decisions. The P25 DSR also describes the organization and relationships of the TIA standards relevant to the components of a TIA LMR system. Understanding the TIA standards organization and relationships provides users, manufacturers, and government agencies a useful roadmap for charting progress and prioritizing TIA LMR standards development efforts in relation to the Project 25 Standard.
The TIA TR-8 Committee meets quarterly to develop, revise, and approve TIA LMR standards documents. The P25 DSR section of this site is updated after each TR-8 Committee meeting to reflect document progress of TIA standards expected to be adopted as part of the Project 25 Standard by the Project 25 Steering Committee. The PSCR program has developed this site on behalf of DHS/OIC to assist in outreach efforts regarding TIA standards relevant for use by the public safety communications community. (P25 Communications Resources provides links to more information.)
P25 DSR updates stem from public TIA P25 standards document publication announcements. The PSCR program and its sponsoring organizations make no claims, promises, or guarantees about the accuracy, completeness, or adequacy of the information contained in the P25 DSR. The P25 DSR is not official TIA/TR-8/P25 content and should be used for general reference only.
