P25 is a standard for the manufacturing of interoperable digital two-way wireless communications products. Sometimes also known as Project 25 or APCO P25, this is a user-driven standard, it is not industry – or Federal government – driven standard.

P25 allows for improved communications within and between agencies – especially emergency service providers. Such intra- and inter-operability is necessary for coordinating efficient and timely responses in our post-911 world.
