Hytera MD612i
Fleet-Wide Coverage. High-Power Transmissions. In-Vehicle Reliability.
Hytera MD612i Commercial Digital Mobile Radio
The Hytera MD612i is a powerful, entry-level Digital Mobile Radio (DMR) engineered specifically for vehicle fleets and dispatch command centers. Operating at up to 50 Watts of power, it delivers a significantly wider coverage footprint than any handheld device. Whether mounted in delivery trucks, school buses, agriculture equipment, or set up as a desk-based control station, the MD612i provides reliable, crystal-clear digital communication that keeps your mobile workforce connected across vast geographic areas.
EQUIP YOUR FLEET WITH RUGGED, IN-VEHICLE COMMUNICATIONS.

High-Visibility LED Display
Aluminum Die-Cast Heatsink
High-Power Extended Range
Handheld portable radios max out at 4 or 5 Watts, limiting their reach. The MD612i operates at up to 50 Watts on VHF (45 Watts on UHF), giving your communications a massive power boost. This allows drivers to stay connected with dispatch across expansive rural routes, sprawling agricultural fields, and dense city grids where weaker signals would drop.
Flexible Installation Options
Every vehicle cabin is different. The MD612i features a sleek, compact profile that can be easily mounted under the dash or between seats using the included heavy-duty bracket. For vehicles with tight space constraints, it supports an optional Remote Control Head, allowing the main radio brain to be securely stored in the trunk or under a seat while only the control panel is mounted on the dashboard.
Seamless Fleet Migration
Upgrading an entire fleet of vehicles can be a massive undertaking. The MD612i features Analog and Digital Auto-Detect, meaning it simultaneously monitors both modes and automatically responds in the correct format. This allows you to upgrade your trucks to digital radios one by one, without losing communication with the older analog units still on the road.
Advanced Digital Efficiency
Maximize your licensed radio spectrum. Built to DMR Tier II standards, the MD612i utilizes Pseudo Trunking technology. This virtual trunking feature automatically scans and assigns whichever digital time slot is currently free, drastically improving call connectivity and frequency efficiency when your fleet is operating during high-traffic hours.

Professional Vehicle Installation
Installing high-power radio equipment in modern commercial vehicles requires specialized knowledge of automotive electrical systems to prevent battery drain or computer interference.
Our mobile installation technicians will professionally mount your MD612i radios, hardwire the power leads directly to the ignition block, and ensure all cables are safely hidden and secured for a factory-finish look.
Command Center Configuration
If you are using the MD612i as a desk-based dispatcher station, we provide the complete desktop ecosystem required to make it functional.
We supply and configure the necessary AC-to-DC power converters, set up high-gain rooftop base station antennas, and run the required low-loss coaxial cabling down to your administrative offices.
Mobile Antenna Tuning
A 50-watt radio will only perform as well as the antenna mounted on the roof. Simply screwing an antenna onto a truck is not enough.
We provide precision RF tuning for every vehicle in your fleet, using specialized meters to optimize the Standing Wave Ratio (SWR) of your mobile NMO antennas, guaranteeing maximum signal projection and protecting the radio from feedback damage.
Wide-Area FCC Licensing
Mobile vehicle fleets often cover entire counties or cross state lines, which heavily complicates the FCC licensing process compared to a single-building operation.
We manage the specialized geographic coordination required for wide-area mobile frequency assignments, ensuring your fleet is legally authorized to transmit high-power signals wherever your routes take you.
How Teltra Can Help
Outfitting a fleet of vehicles with communications gear is vastly different from handing out portable radios. It requires expert automotive installation, precise antenna tuning, and wide-area frequency planning. At Teltra, we specialize in mobile fleet deployments. Whether you need the Hytera MD612i installed in a dozen delivery trucks, integrated into heavy agricultural machinery, or set up as a powerful desk-bound control station for your dispatchers, our engineering team ensures your mobile workforce is connected, optimized, and ready to hit the road safely.
