APX900 — 48-Channel Dual-Mode No-Display with IP68
The value rung of the P25 APX line: 48-channel capacity, dual-mode P25 Phase 1/2 plus analog operation for incremental migration, no-display form factor for rugged simplicity, and IP68 submersible rating. The migration argument: departments keep legacy analog channels alive today while standardizing on P25 interoperability for mutual aid, with AES-256 encryption readiness as funding allows. The APX900 delivers P25 compliance and the APX ruggedness standard at the lowest acquisition cost in the line — the pragmatic entry point for agencies where budget is the binding constraint.
MTP850 — TETRA Flagship with Full Keypad, SDS, WAP, and TEA
The TETRA flagship: 2.0-inch display with full alphanumeric keypad, SDS text messaging for workforce dispatch, WAP data services for field applications, and TEA encryption — the complete secure-communications feature set for government and utility agencies. The infrastructure argument: TETRA trunking delivers guaranteed spectral efficiency, standardized encryption, and cross-agency interoperability as native features, at a premium infrastructure cost that agencies with mandated secure-interoperability requirements are obligated to bear. P25 and TETRA serve the same mission from different regulatory ecosystems.
