MTP850 — TETRA with 2.0" Display, Full Keypad, SDS Messaging, WAP Browser, and TEA Encryption
High-tier TETRA portable with 2.0-inch full-color display and alphanumeric keypad supporting SDS text messaging and WAP browser data applications — extending the radio beyond voice into data services. TEA end-to-end encryption secures voice and data. The data-workflow choice for public transport, airport operations, and security dispatch teams whose operations are text-driven: sending assignments, receiving acknowledgements, and querying data services directly from the radio. Where the operator's job is messaging and data access rather than location reporting or power adaptation, MTP850's browser-and-keyboard focus wins — the enterprise TETRA standard for text-centric operations.
MTP6550 — Proven TETRA with Class 3L 1.8W Adaptive Output, GPS, and 16-Hour Battery
Proven high-tier TETRA portable with full-color 2.0-inch display and alphanumeric keypad for SDS messaging. Class 3L 1.8W adaptive RF output self-regulates for battery conservation — extending shift runtime to 16 hours on standard cells. Integrated GPS for workforce tracking. The field-operations choice for utilities, emergency services, and security patrols where adaptive power management and location reporting matter more than data-browsing: the Class 3L self-regulation delivers the battery discipline that keeps crews on-air through full shifts, and GPS keeps supervisors aware of field positions — at a proven, battle-tested platform price point.
