The P25 Capabilities Guide document can be downloaded using the link below.

Project 25 Capabilities Guide V 1.8 May 2025

This document is intended as a guide that lists the capabilities of subscriber and infrastructure equipment enabled by the TIA-102 series of published standards. These standards are referred to as the “Project 25 Standard”.

The most common differentiator for both subscriber and infrastructure equipment are the air interfaces. This guide groups the listed equipment capabilities by the currently available standardized air interfaces:

FDMA Conventional
FDMA Trunking
TDMA Trunking

For each air interface grouping, this guide provides both a summary of capabilities and a more detailed listing which expands on the capabilities identified in the summary. This approach is used for both subscriber and infrastructure equipment. Within the tables of this guide, detailed references to the TIA-102 series documents are included.

At a minimum, two types of tables are provided in each section. There will be a high-level summary table titled “Feature Summary” for the services followed by a second table with details about the features under each service titled “Feature Detail.” The high-level summary will also list the frequency bands.

It should not be expected that ALL of the services and features contained in these tables will be included in P25 Infrastructure or in a P25 subscriber unit. The P25/TIA-102 Standard defines many services and features. System operators and users will need to make choices as to which features and services are required for their particular situation.
