Technical guide for planning a voice network migration from analog to P25 Phase 2 in public security organizations. Coverage, interoperability with legacy systems, Zetron dispatch consoles, and operational change management.
Peru's National Police operates a heterogeneous mix of communication equipment: legacy analog VHF from the 1990s, analog UHF from the last decade, some DMR Tier II in Lima, and limited P25 Phase 1 in specialized units (DIROES, DINOES). This fragmentation means officers from different divisions cannot communicate directly during joint operations.
P25 Phase 2 is the reference standard for defense and police in Peru for three concrete reasons: native interoperability with U.S. allies (DEA, Coast Guard, FBI in Pacific counter-narcotics), an existing base of P25 equipment in Peruvian Armed Forces, and spectral efficiency (Phase 2 TDMA doubles channel capacity vs. Phase 1 FDMA in the same spectrum).
A Lima Metropolitan coverage network requires 12-15 repeater sites minimum (20-30 for redundancy). Zetron MAX dispatch console integrates P25, VoIP, voice recording, and CAD in a single workstation. Migration proceeds in 3 phases over 18-36 months, with P25/analog gateway bridges ensuring zero operational degradation during transition. EMAR SYSTEMS provides commissioning support, coverage testing, and personnel training.
