The L17 is a compact 4G SOS GPS smart bracelet built for personal safety and health monitoring. Designed in a wristwatch form factor (IP67), the L17 combines reliable GNSS positioning, LTE cellular connectivity, and optional Bluetooth sensors to deliver Green-Gps compatible real-time tracking and telemetry for children, seniors, lone workers, and general personal asset protection.
The device pairs sensor-rich health tracking (heart rate, SpO2, blood pressure and temperature) with an SOS button and two-way calling for immediate response. With long battery life, nano-SIM / eSIM support and global LTE/GSM band coverage, the L17 is ideal where continuous location, emergency alerts and compact wearable telemetry are required.
Key Highlights
- Green-Gps compatible GPS tracker: delivers real-time tracking and telemetry to Green-Gps for alerts, history and reports.
- 4G LTE connectivity with global band support: reliable cellular positioning and data transmission for wide-area coverage.
- Integrated health sensors: heart rate, SpO2, blood pressure and temperature combined with activity/fall detection.
- SOS and two-way calling: one-touch emergency alerting plus voice communication to assist in critical events.
- Compact, waterproof wearable: IP67 wristwatch form factor for continuous personal use and comfortable daily wear.
- Optional BLE 5.0: local Bluetooth sensors and beacons can extend telemetry and short-range monitoring.
- Server-side history and alarms: geo-fencing, low-battery and SOS alarms with 30-day server storage for audit and review.
How It Works with Green-Gps
The L17 sends GNSS location fixes and sensor telemetry over its LTE cellular link to cloud services. When configured with Green-Gps, those data streams feed into Green-Gps’s real-time tracking dashboard, alarm engine and historical reports so you can monitor location, health events and SOS alerts from a single interface.
- Real-time location and telemetry updates: GNSS fixes (MTK3333) transmitted over LTE provide live position on Green-Gps maps.
- SOS and voice events: SOS button presses and two-way calls generate instant alerts that Green-Gps can forward to responders.
- Health and activity telemetry: heart rate, SpO2, blood pressure, temperature and accelerometer-based activity/fall data are available to Green-Gps for monitoring and triggers.
- Bluetooth sensors: optional BLE 5.0 enables short-range beacons or sensors; paired data can be relayed to Green-Gps for expanded telemetry.
- Historical tracking & geo-fencing: device history and geo-fence events are stored (up to 30 days on server) and viewable in Green-Gps for compliance and review.

Why Choose This Tracker with Green-Gps
Integrating the L17 with Green-Gps gives you a Green-Gps compatible wearable that focuses on reliable personal safety and health telemetry rather than vehicle-focused features. Use the L17 when you need accurate GNSS location, cellular-backed real-time tracking, and sensor-rich health data from a comfortable wrist device. Its SOS button, two-way calling and server-side history make it straightforward to manage incident response and audit trails.
For organizations and families that rely on Green-Gps for dashboards, alerts and reporting, the L17 offers a compact, sensor-packed GPS tracker that simplifies deployment and ongoing management. While the L17 is optimized for people-first applications, its BLE capability and robust cellular bands enable flexible telemetry integration—useful in scenarios where asset-level monitoring or proximity sensor data must be combined with location and emergency events.
