P25
P25, or Project 25, is a digital radio standard used primarily by public safety organizations in North America. It was developed to ensure reliable communication among emergency services, such as police, fire, and medical responders. P25 systems allow for interoperability, meaning different agencies can communicate effectively during emergencies.
The P25 standard includes various phases, with Phase 1 using analog and digital voice channels, while Phase 2 offers improved capacity and efficiency through time division multiple access (TDMA). This technology enhances the clarity and security of communications, making it essential for first responders in critical situations.
