GL521MG Queclink Asset Tracker
Description: The GL521MG is derived from our successful GL500MG by supporting NB2 and adding Qi wireless charging and BLE. Our customers love the battery-powered GL500MG but still wanted a rechargeable version for certain scenarios. We designed this version without impacting the waterproof and robust enclosure. Adding BLE allows connectivity to diverse wireless accessories. 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, high-value static asset monitoring and more. The GL521MG supports several mounting alternatives which use unique clip on design to securely attach the device to any asset. **Data Cable Sold Separately: GL500 Data Cable **WIRELESS CHARGER SOLD SEPARATELY: GL521MG Wireless Charger Queclink Flyer - Click to Open PDF Features: Rapid & Covert Install 1-Year Standby Time with Internal Battery Supports Wireless Charging OTA Control Scheduled Timing Report Geo-fences Waterproof Low Power Alarm Wakeup Report Motion Detection Automatic Mode Switching Temperature Monitoring Tamper Detection Supports BLE 4.2 Magnetic or Tapping Screw Mounting (Optional Ad-on) Specifications: Operating Band Cat M1/Cat NB2:Cat M1:LTE-FDD: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B26/B27/B28/B66/B85Cat NB2:LTE-FDD: B1/B2/B3/B4/B5/B8/B12/B13/B18/B19/B20/B25/B28/B66/B71/B85EGPRS: 850/900/1800/1900 MHz Data Transmission eMTC (DL) 588 KbpseMTC (UL) 1119 KbpsNB2 (DL) 127 KbpsNB2 (UL) 158.5 Kbps Frequency EGPRS 850 / 900 / 1800 / 1900 MHz Data Transmission GPRS multi-slot class 33 (33 by default)EDGE multi-slot class 33 (33 by default) GNSS Type u-blox All-in-One GNSS receiver Sensitivity Autonomous: -147 dBmHot Start: -156 dBmReacquisition: -160 dBmTracking: -162 dBm Position Accuracy (CEP) Autonomous: < 2.5m TTFF (Open Sky) Cold Start: 27s averageWarm Start: 27s averageHot Start: 1s average Dimensions 87 × 51 × 30mm3.43’’(L) × 2.01’’(W) × 1.18’’(H)87 × 51 × 33.5mm3.43’’(L) × 2.01’’(W) × 1.32’’(H) (magnetic case mounting version) Weight 150g (5.29oz)170g (6.0oz) (magnet-mounted version) Internal Battery Li-Polymer 3.7V/2400mAH Standby Time Standby current: < 10 µA1 report per day: 1 year*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.
