Queclink GV57CEU

Queclink GV57CEU — LTE Cat 1 Waterproof Vehicle Tracker for E-mobility and Fleet Applications

The Queclink GV57CEU is a versatile LTE Cat 1 vehicle tracker designed for a wide range of transportation and e-mobility applications including micromobility, stolen vehicle recovery, automobile finance and logistics. Its IP67-rated waterproof casing ensures long-term reliability in humid and harsh environments, while its wide operating voltage range of 9–90V DC makes it compatible with electric vehicles including e-bikes, scooters, golf carts and a full range of conventional vehicles.

Measuring just 84 × 50 × 16.6mm and weighing 76g, the GV57CEU delivers LTE Cat 1 connectivity across a broad range of FDD bands (B1/B2/B3/B4/B5/B7/B8/B20/B28) with automatic 2G fallback, ensuring continuous coverage across the UK, Europe and North America. BLE 5.2 enables wireless connectivity to driver identification key fobs, temperature sensors and other Queclink accessories.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV57CEU directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.
