How It Works with Green-Gps
The L15 transmits location and telemetry to Green-Gps over its 4G cellular link (SIM7500A) and supplements outdoor GPS with BLE, Wi‑Fi and LBS for improved indoor/hybrid positioning. Green-Gps ingests the device’s GPS coordinates, battery and sensor telemetry, SOS events and activity reports so caregivers receive real-time alerts, location history and status updates through the Green-Gps interface or mobile apps.
- Real-time location and telemetry updates via 4G (SIM7500A) with GPS and dual LDS antennas.
- SOS event reporting plus two-way voice calls routed for caregiver response and verification.
- Battery level and charging status for remote monitoring of device availability.
- Activity and motion data from the 3D accelerometer (step counting, movement events, fall detection workflows as configured in Green-Gps).
- BLE 5.0 support for indoor positioning and for pairing Bluetooth sensors or beacons to improve accuracy.
- Optional infrared temperature readings and periodic notifications for wellbeing monitoring.
- Replaceable nano SIM enables straightforward provisioning and carrier management within Green-Gps.
