GL601MG

Queclink GL601MG — Solar-Powered LTE Cat M1/NB2 Asset Tracker with 10-Year Standby

The Queclink GL601MG is a solar-assisted LTE Cat M1/NB2 asset tracker engineered for long-term deployment on unpowered assets such as trailers, containers, and agricultural equipment. Its large-area solar panel continuously recharges the internal battery, enabling up to 10 years of standby operation and eliminating the need for manual battery replacement in the field.

Typical Use Cases

• Long-Term Container Fleet Monitoring: Deploy and forget — the GL601MG's solar recharging and 10-year standby means shipping containers can be tracked for their entire operational lifetime without a single maintenance visit.

  
  

• Rail Wagon and Rolling Stock Tracking: Attach to the underside or sides of rail wagons for continuous position and status reporting across national and international rail networks.

  
  

• Intermodal Asset Management: Track containers moving seamlessly between road, rail, and sea transport modes with a single always-on device.

  
  

• Trailer Fleet Visibility: Monitor trailer location, utilisation, and temperature status across large transport fleets without battery management overhead.

  
  

• Temperature-Sensitive Cargo Monitoring: Use the integrated temperature sensor to log and alert on temperature excursions during cold chain pharmaceutical, food, or chemical transport.

  
  

• Port and Depot Asset Management: Track containers and trailers across large port facilities using WiFi positioning to supplement GPS in GNSS-shadowed areas near cranes and warehouses.

  
  

• Agricultural Equipment and Seasonal Assets: Leave the GL601MG fitted to seasonal machinery and let solar recharging keep the device live through extended storage periods.

  
  

• Infrastructure and Utility Equipment: Track generator sets, cable drums, and utility equipment across distributed infrastructure projects without access to vehicle power.

  
  

• Remote Area Asset Tracking: Solar recharging makes the GL601MG ideal for agricultural tracking in areas too remote to return to for battery replacement.

  
  

• Construction and Mining Equipment: Monitor large plant equipment across multi-year project sites with tamper alerts ensuring devices remain in place throughout deployment.

  
  

Frequently Asked Questions

How does the solar charging work on the GL601MG?

The GL601MG incorporates solar panels that continuously recharge the 12,000mAh battery bank during daylight hours. With sufficient solar exposure the device can operate for 10 years without any manual battery replacement, making it effectively maintenance-free for the life of most asset deployments.

What happens if there is no sunlight for extended periods?

Without solar input, the 12,000mAh battery bank provides up to 5 years of standby at 1 report per day. Even through winter months or indoor storage periods, the device will continue operating — and will resume solar charging once sunlight is available again.

Does the GL601MG work worldwide?

Yes — the GL601MG is certified for global deployment with LTE Cat M1/NB2 connectivity and EGPRS fallback covering major network bands worldwide.

What sensors are built into the GL601MG?

The GL601MG includes a temperature sensor for cold chain monitoring, a tamper detection sensor for security alerting, and a light sensor that can detect when a container is opened or a storage cover is removed — providing multiple layers of asset intelligence.

Can the GL601MG be used in areas without 4G coverage?

Yes — the GL601MG falls back to 2G EGPRS on 850/900/1800/1900 MHz when LTE Cat M1/NB2 is unavailable, ensuring connectivity in remote or less developed network regions.
