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 Plaspy-compatible indoor tracking and alarm-driven monitoring.
Built to integrate with Plaspy-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 Plaspy 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 Plaspy compatible.
How It Works with Plaspy
The MT-350 pairs with UWB ceiling base stations to create a high-precision indoor RTLS. When integrated with Plaspy, the wristband's location and status messages are forwarded to the Plaspy platform for unified mapping, alerting and reporting. Plaspy-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 Plaspy.
- 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 Plaspy 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 Plaspy
The MT-350 offers focused indoor positioning performance that complements Plaspy’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 Plaspy-compatible architectures to provide seamless handover: use GPS-enabled Plaspy 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.
