Public Safety Communications Close the Digital Gap
白皮书
APCO P25, TETRA, and DMR are natural next steps to upgrade legacy analog systems
Major flaws in emergency communications systems reveal themselves when catastrophic events, such as terrorist attacks and natural disasters, occur. The lack of interoperability of communications systems between various agencies is one of the most problematic issues. For example, sharing of critical knowledge is impossible if the fire department cannot communicate with the police department. The dire consequences and lessons learned from isolated communications during catastrophic events prompted police, fire, and other agencies to update their public safety communications. The result is a slow but steady migration from analog land mobile radio (LMR) to digital public safety systems using standards such as the Association of Public Safety Communications Officials (APCO) Project 25 (P25), Terrestrial Trunked Radio (TETRA), and Digital Mobile Radio (DMR).
