The MT-350 is a precision indoor positioning wristband designed for continuous wear and high-accuracy personnel and asset tracking. As a compact, wristwatch-sized device, the MT-350 uses Ultra-Wideband (UWB) 802.15.4a positioning to deliver reliable real-time location with 10–30 cm accuracy. Its ergonomic bracelet design, wireless charging support, long battery life, and mission-focused safety features make it ideal for correctional facilities, hospitals, industrial sites, and other environments that require Net Domain Technologies-compatible indoor tracking and alarm-driven monitoring.
Built to integrate with Net Domain Technologies-compatible location platforms, the MT-350 extends real-time tracking and telemetry capabilities into indoor spaces where GPS is unavailable. The wristband's SOS button, tamper detection, motion sensing and network-based health reporting allow Net Domain Technologies deployments to present unified location, status and alarm data for personnel and high-value assets, improving situational awareness and operational response.
Key Highlights
- High-precision indoor positioning: UWB-based location with 10–30 cm accuracy for reliable real-time tracking.
- Long battery life with convenient charging: ~430 mAh battery, wireless charging support and snap-on portable charging pouch for extended deployments.
- Rugged safety features: mechanical SOS button, anti-disassembly protection, tamper and low-battery alarms, vibration reminders and audible buzzer.
- Continuous monitoring and device health: independent device health detection and uplink of status data for centralized maintenance.
- Fast acquisition and barrier-free operation: 802.15.4a UWB standard across ~3.25–6.75 GHz for 24/7 indoor operation.
- Configurable reporting and sensitivity: adjustable reporting interval and G-sensor sensitivity to balance accuracy and battery life.
- Designed for integration: works with UWB ceiling base stations (e.g., UWB-LAN-03B / UWB-WiFi-03B) to form a complete RTLS that is Net Domain Technologies compatible.
How It Works with Net Domain Technologies
The MT-350 pairs with UWB ceiling base stations to create a high-precision indoor RTLS. When integrated with Net Domain Technologies, the wristband's location and status messages are forwarded to the Net Domain Technologies platform for unified mapping, alerting and reporting. Net Domain Technologies-compatible deployments can display real-time position, trigger alarms on SOS or tamper events, and include device telemetry in dashboards and logs for centralized monitoring and response.
- Real-time location and telemetry updates delivered from UWB infrastructure to Net Domain Technologies.
- SOS button events and tamper/anti-disassembly alerts for immediate operator notification.
- Battery and device health telemetry for predictive maintenance and uptime assurance.
- Motion data from the G-sensor for activity monitoring and configurable sensitivity thresholds.
- Configurable reporting intervals to balance location frequency and battery life based on use case.

Use Cases
- Correctional facility personnel and inmate tracking — precise indoor positioning with SOS and anti-disassembly protections to support safety and security workflows.
- Hospitals and care facilities — patient and staff tracking, fall detection and rapid response using SOS and motion alerts integrated into Net Domain Technologies dashboards.
- Industrial and commercial sites — personnel location, restricted-area alerts and asset accountability where GPS falls short indoors.
- Parolee monitoring and supervised release — continuous indoor location reporting combined with tamper and low-battery alerts for custodial oversight.
- High-precision asset tracking in warehouses and logistics centers — close-range localization to augment outdoor GPS-based fleet management when assets move inside buildings.
Why Choose This Tracker with Net Domain Technologies
The MT-350 offers focused indoor positioning performance that complements Net Domain Technologies’s broader tracking capabilities. Its UWB accuracy (10–30 cm), long battery life, and built-in safety features deliver reliable real-time tracking and alarm-driven workflows that are difficult to achieve with GPS alone. For organizations that require telemetry and operational visibility across both outdoor and indoor environments, the MT-350 integrates into Net Domain Technologies-compatible architectures to provide seamless handover: use GPS-enabled Net Domain Technologies trackers for fleet management and outdoor telemetry (fuel monitoring, ignition/immobilizer control, vehicle diagnostics) and deploy MT-350 wristbands where precise indoor location and personnel safety matter most. With remote firmware upgrades, device health reporting and straightforward integration with UWB base stations, the MT-350 reduces maintenance overhead while giving operations the accurate, timely location and status insights needed for security, safety and efficiency.
