Product ID: DM4401e
The MOTOTRBO DM4401e mobile radio is an advanced transceiver featuring a numeric display, integrated GNSS (GPS/GLONASS) location tracking, Bluetooth 4.0, Wi-Fi, and full support for DMR Tier II and Tier III trunked systems.
Product features:
DMR – analogue and digital operation with support for DMR Tier II and Tier III trunking 
Integrated GNSS (GPS and GLONASS) for outdoor tracking and indoor location tracking capability 
Built-in Bluetooth 4.0 for wireless audio accessories and data connectivity 
Integrated Wi-Fi enabling over-the-air software updates (OTAP) 
IMPRES™ Audio architecture, Intelligent Audio, and certified IP54 and MIL-STD 810 durability • Product description
The MOTOTRBO DM4401e enhances mobile operations by incorporating integrated GNSS (GPS and GLONASS) and Bluetooth 4.0 as standard features. This enables precise real-time vehicle location tracking outdoors alongside indoor positioning capabilities. Integrated Bluetooth allows drivers to connect wireless audio accessories and transfer data effortlessly without extra cabling in the vehicle cab.
Featuring IMPRES™ audio architecture and Intelligent Audio, the DM4401e dynamically suppresses background noise, prevents acoustic feedback, and balances speaker volume based on cabin noise levels. Built-in Wi-Fi enables seamless over-the-air firmware maintenance, keeping fleet devices updated without taking vehicles offline.
Designed for critical environments, the DM4401e features AES256 encryption support, Lone Worker monitoring, Transmit Interrupt prioritization, and digital emergency alerts. It integrates across all MOTOTRBO system architectures, from Conventional and IP Site Connect to Capacity Plus and Capacity Max trunked networks. Tested to MIL-STD 810 and IP54 standards, it ensures total reliability in demanding field conditions.
The MOTOTRBO DM4401e is engineered for logistics fleets, emergency services, mining, energy, and public transit organizations that require location tracking and wireless accessory integration.
Emergency & utility services: real-time GNSS location dispatching combined with wireless Bluetooth headset support.
Transport & logistics: safe fleet management across wide-area DMR Tier III trunked networks.
Mining & industrial sites: reliable voice communications with indoor location tracking and AES256 data encryption.
