Motorola MTP3100 — Compact Voice-First TETRA at 290g
Compact TETRA portable with a 1.8-inch display and simplified voice-first user interface, 30g lighter than the full-featured MTP850 at 290g. Class 3L 1.8W adaptive RF with basic TEA encryption. Integrated GPS for location tracking — the same positioning core as the MTP850 but without WAP browser and SDS text messaging. IP55 rated with MIL-STD-810F certification, 1,850mAh battery delivering 15 hours, and a simplified keypad without alphanumeric input for pure push-to-talk operations. Built for frontline patrol officers, fire crews, and transit workers where TETRA voice, GPS location and the lighter form factor matter more than data applications.
Motorola MTP3500 — Wi-Fi Provisioning Mainstream with 19-Hour Runtime
Mainstream TETRA portable with a 2.0-inch color display and integrated Wi-Fi for over-the-air programming and firmware updates without a docking station. Class 3L 1.8W adaptive RF output with TEA end-to-end encryption at air interface class 3. GPS tracking for fleet management. IP67 rated with MIL-STD-810G certification and a 2,100mAh battery delivering 19 hours — four hours beyond the MTP3100. The fleet-scale choice when wireless provisioning, longer shifts and higher environmental sealing justify the step up from the entry terminal.

The Field Upgrade Decision
Choose the MTP3100 when the workforce is voice-first: frontline patrol, fire crews and transit workers gain the same TETRA interoperability, GPS core and 1.8W adaptive output in a 290g terminal with a simplified PTT interface — the cost-optimized entry to the Motorola TETRA ecosystem. Choose the MTP3500 when the fleet needs wireless operations: Wi-Fi over-the-air programming removes docking-station logistics for firmware updates, TEA end-to-end encryption at class 3 raises the security tier, and the 2,100mAh battery adds four hours across a 19-hour shift while IP67 extends deployment into harsher environments. MTP3100 optimizes the price of TETRA voice; MTP3500 optimizes the cost of operating a TETRA fleet at scale.
