Motorola MTP3500 — New-Gen TETRA with Wi-Fi OTA Provisioning
Full-featured TETRA portable with 1.8W Class 3L adaptive RF output and 2.0-inch color display. Integrated Wi-Fi for over-the-air programming and firmware updates — eliminating docking-station dependency for fleet management — plus GPS tracking for outdoor fleet visibility. TEA end-to-end encryption with air interface class 3, IP67 with MIL-STD-810G certification, and a 2,100mAh battery delivering 19 hours with intelligent power management. The provisioning-light answer for fleets that re-program radios remotely.
Motorola MTP6550 — Proven TETRA Data Terminal with Full Keypad
High-tier TETRA portable built for data-heavy operations: full alphanumeric keypad for SDS text messaging and status dispatch, full-color 2.0-inch display, and WAP browser for on-radio data applications. Class 3L 1.8W adaptive RF output self-regulates for battery conservation, extending shift runtime to 16 hours on the 1,850mAh Li-Ion cell. Integrated GPS for workforce tracking, TEA end-to-end encryption, IP55 with MIL-STD-810F, and a 310g form factor with large tactile buttons for gloved-hand operation. The workforce-management workhorse of utilities and emergency services.

The Fleet Upgrade Decision
Choose the MTP3500 when your TETRA fleet is distributed and every truck-roll to a docking station costs money: Wi-Fi OTA provisioning and firmware updates let you re-program radios over the air, while the 19-hour battery and IP67 rating carry patrols through extended shifts and weather. Choose the MTP6550 when the job is text-driven: field supervisors and dispatch teams that live in SDS status messages, job assignments and WAP data lookups across a full shift benefit from the alphanumeric keypad workflow, and the 310g gloved-hand form factor suits emergency-service operations. The MTP3500 buys remote fleet manageability and runtime; the MTP6550 buys a keyboard-centric data workflow proven across European police and utility fleets.
