Project 25 Documents & Standards Reference
User Needs
Public safety communication system users are responsible for providing and maintaining their user needs in the form of a system requirements document. The Steering Committee, with the involvement of its P25 UNS, establishes the priorities and scope for technical development by TIA of new and revised P25 standards.
The P25 UNS’ ongoing ongoing development of the P25 SoR, as approved by the Steering Committee, plays an essential role in not only developing standards that meet users’ needs but also to establish the basis upon which equipment and systems can be assessed as being compliant with the P25 standards. The P25 SoR also establishes a feasible migration path for P25 equipment and systems to take advantage of emerging technologies. As a result, the P25 SoR establishes a balance between user needs and what industry is able to implement based on current physical, technological, and regulatory constraints.
