II. Overview

Quectel EC21 Mini PCIe is a series of LTE Cat 1 module adopting standard PCI Express® Mini Card form factor (Mini PCIe). Specially optimized for M2M and IoT applications, it features cost-effective, low-power LTE connectivity, and delivers M2M-optimized speeds of 10 Mbps downlink and 5 Mbps uplink. These make it ideal for numerous IoT applications that are not reliant on high speed connectivity but still require the longevity and reliability of LTE networks.

EC21 series Mini PCIe contains 10 variants: EC21-A Mini PCIe, EC21-V Mini PCIe, EC21-AUT Mini PCIe, EC21-AU Mini PCIe, EC21-AUX Mini PCIe, EC21-E Mini PCIe, EC21-EU Mini PCIe, EC21-EUX Mini PCIe, EC21-KL Mini PCIe and EC21-J Mini PCIe. This makes it backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can easily migrate from LTE to 2G or 3G network.

EC21 series Mini PCIe supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BDS, Galileo and QZSS). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning.

A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB serial drivers for Windows 7/8/8.1/10/11, Linux and Android) extend the applicability of the module to a wide range of M2M applications such as smart metering, tracking and tracing, fleet management, wearable devices, smart home gateways, and  digital signage.
