P25 radio systems are built with public safety in mind, with increasing adoption across utilities, transportation and federal. These systems work well for everyday communications, yet are specifically designed to meet operational voice and data requirements for critical communications during instances of community disasters, terrorist threats and other natural catastrophes.
With P25, you can be confident that you have the best radio technology available to meet your communication needs.
The P25 Compliance Assessment Program (P25 CAP) provides independent, standardized testing conducted by accredited laboratories to verify that equipment identified under P25 complies with program standards. L3Harris is credited with the first P25-compliant device and has been committed to the program ever since. This testing and documentation instills confidence in the reliability and performance of communications equipment, and ensures seamless interoperability between agencies and organizations. This matters because it isn’t just about meeting criteria; it’s about instilling confidence in the reliability and performance of your communications equipment.

A key element to P25 is its defined system interfaces that are integral to building P25 communication networks. P25 defines various interfaces to enable seamless communication between different components within the network including:
Provides a standard way for P25 subscriber units to communicate with each other and P25 Radio Frequency Subsystems (RFSSs).
Provides a secure interoperable method to interface P25 RFSSs. These RFSSs may be from different manufacturers or the same manufacturer.
Provides a secure interoperable method to interface P25 consoles with P25 RFSSs.
Provides the capability to interface P25 Conventional systems with Dispatch.
Provides a standard capability to interface a keyloader with 25 Subscriber Units (SU).
The P25 standard is a mature and versatile technology that can easily adapt to unique user needs and budget constraints. Its flexible configurations make it an ideal choice for various applications, providing a reliable and cost-effective solution for critical communications.
