The Queclink GL501MG is a compact, battery-powered GPS tracker designed for long-term unattended asset monitoring and is Plaspy compatible out of the box. Based on the proven GL500MG platform, the GL501MG adds LTE Cat M1 / NB1 connectivity with 2G fallback, Qi wireless charging and Bluetooth Low Energy (BLE) to deliver reliable real-time tracking and low-power telemetry for lot management, cold-chain and warehouse assets.
Engineered for durability and low maintenance, the GL501MG combines an internal u‑blox GNSS receiver (<2.5 m CEP autonomous), IP67 waterproofing, internal temperature and light sensors, and an ultra low standby current to provide up to one year of standby life at one report per day. Its sealed enclosure, internal antennas and optional magnetic case make it easy to deploy while maintaining a secure, Plaspy-compatible data feed for fleet management, anti-theft monitoring and environmental telemetry.
Key Highlights
- Plaspy compatible GPS tracker with LTE Cat M1 / Cat NB1 and EGPRS (2G) fallback for global coverage and low-power reporting.
- High-sensitivity u‑blox GNSS with <2.5 m CEP autonomous accuracy and fast TTFF for dependable real-time tracking.
- Long battery life from an internal 3.7V / 2400mAh Li‑Polymer battery and ultra low standby (<10 µA) — up to one year at 1 report/day.
- Built-in BLE 4.2 for accessory connectivity and configuration, enabling Bluetooth sensors and proximity workflows.
- IP67 waterproof enclosure, internal sensors (temperature and light) and internal 3-axis accelerometer for telemetry and tamper detection.
- Qi wireless charging (5V/1A) and vibration motor for convenient user operation; optional magnetic-case mounting for metal surfaces.
- Plaspy-ready data transport via @Track protocol over TCP, UDP or SMS to support scheduled reports, wake-up events and alerts.
How It Works with Plaspy
The GL501MG transmits location and onboard telemetry using the @Track protocol and supports TCP, UDP or SMS transport, making it straightforward to integrate with Plaspy’s ingestion endpoints. Once paired in Plaspy, the tracker supplies frequent location updates, motion and tamper signals, and internal sensor readings so you can monitor assets in real time and trigger automated workflows.
- Real-time location and telemetry updates via LTE Cat M1/NB1 (with 2G fallback) for resilient connectivity.
- Onboard status: motion, low battery alarm, tamper (light sensor + accelerometer) and wakeup reports for reliable anti-theft alerts.
- Internal temperature sensor and light sensor telemetry suitable for cold-chain or warehouse environmental monitoring.
- BLE 4.2 support for Bluetooth sensors and accessory pairing to extend telemetry capabilities (e.g., temperature probes or beacons).
- Flexible reporting: scheduled timing reports, intelligent reporting frequency adjustment and up to 20 internal geo-fence regions for geofencing alerts in Plaspy.
