1. Global LTE Cat M1/NB2 with 2G fallback using unique antenna solution

2. Up to 7-year standby time

3. Waterproof, compliant to IP67

4. Rapid and flexible installation

5. Ideal for asset monitoring and lot management

*The standby time is estimated under the condition of operating with LTE CAT M1/NB-IoT and the CSQ is greater than 15, working at a constant ambient temperature of 25°C and reporting once a day without any sensors.

The GL520MG is an easy-to-deploy asset tracker built on Queclink’s innovative power management technology. It lasts for up to seven years and features one of the longest battery lives among devices of its size in the market. The built-in light sensors make the product sensitive to tamper attempts and its waterproof design allows it to be used in harsh environments. With internal temperature and light sensors, the product is ideal for a wide range of environmental monitoring applications such as cold chain logistics, warehouse management, cargo trucking, highvalue static asset monitoring and more. The GL520MG supports several mounting alternatives which use unique clip on design to securely attach the device to any asset.
