APX 4500 — 110W P25 Phase 2 Mobile with Dual Control Head, 3.4kg, and OTAR Key Management
Full-size P25 Phase 2 mobile with 110W RF output — the highest power class in this comparison — in a 3.4kg chassis. Dual control heads support two-position operation, letting command vehicles run dispatch from front and rear seats with one radio. Enhanced audio architecture for high-noise patrol environments. AES-256 encryption with OTAR over-the-air key management, standard for public-safety interoperability. GPS/GLONASS. Designed for police interceptors, fire command units, and EMS supervisor vehicles where P25 Phase 2 trunking compliance, 110W coverage reach, and encrypted multi-agency interoperability are contractual requirements rather than optional features.
DM4601e — 1-45W DMR Mobile with SINC+ 102 Phon Audio, 2.4" QVGA, and Wi-Fi OTA Programming
High-tier DMR mobile with 1-45W variable RF output for power conservation on short-range deployments — 65W below APX4500's peak but 45W covers citywide fleet coverage in most commercial applications. SINC+ AI noise cancellation delivers 102 phon loudness. 2.4-inch QVGA full-color display with numeric keypad and text messaging. Wi-Fi OTA for wireless programming and software updates without pulling the unit from the vehicle. GPS/GLONASS. Capacity Max / DMR Tier III trunking ready. The fleet-optimized choice for logistics companies, utilities, and municipal service fleets where MOTOTRBO ecosystem economics, variable power control, and Wi-Fi field programming outweigh P25 public-safety protocol requirements.
