Project 25: Standards & Measurement

Project 25 (P25 or APCO-25) is a suite of standards for interoperable Land mobile radio system (LMR) systems designed primarily for public safety users. The standards allow analog conventional, digital conventional, digital trunked, or mixed-mode systems. P25 was originally developed for public safety users in the United States but has also gained…
