Overview
The GL330MG is an upgraded version of Queclink’s classic GL3xx series, which is one of the most popular products in their range of asset trackers with worldwide deployment. It is with optimised power consumption and BLE/Wi-Fi added, which can be used for a wide range of applications which require real-time location, such as private investigations, package delivery, temporary tracking of vehicles, long distance transportation, endurance racing and animal management.
The tracker runs on LTE Cat M1, NB1 and NB2. BLE 5.2 and 2.4 GHz Wi-Fi scanning support indoor positioning or a mode switch. A USB Type-C port is used for external power and configuration.
Internal cellular, GNSS and BLE/Wi-Fi antennas sit in a 77.9 × 39.9 × 26.7 mm case. CELL, GPS and PWR LEDs show status, and a function button sends an emergency alert.
LTE Cat M1, NB1 and NB2 in one device, with region Global, according to the datasheet.
A function button sends an SOS or emergency alarm, with vibration feedback.
USB Type-C is used for external power and configuration; charging voltage is 5 V DC.
GPS, BeiDou, Galileo and GLONASS, with Wi-Fi scanning for indoor positioning or a mode switch.
BLE 5.2 at 2.4 GHz, according to the datasheet.
Up to 10 geo-fence regions, plus scheduled reports by time, distance or mileage.
Configuration and firmware can be updated over the air, according to the product page.
Always online without reporting is rated at 2000 hours, according to the datasheet.

Compliance
Approvals listed on the Queclink datasheet.
Applications
Reports real-time location for package delivery, temporary vehicle tracking and long-distance transport. GPS, BeiDou, Galileo and GLONASS, with Wi-Fi scanning, keep a fix indoors and out.
A function button sends an SOS or emergency alarm, with vibration feedback, for personal safety management.
Used for temporary tracking of vehicles. Geo-fences cover up to 10 regions, and motion detection uses the internal 3-axis accelerometer.
