Quectel EC21 is a series of LTE Cat 1 module optimized specially for M2M and IoT applications. It features cost-effective, low-power LTE connectivity, and delivers maximum data rates up to 10 Mbps downlink and 5 Mbps uplink. These make EC21 series an ideal solution for numerous IoT applications that are not reliant on high speed connectivity but still require the longevity and reliability of LTE networks.

EC21 series is compatible with Quectel multi-mode LTE Standard EC25 series/EC20-CE/EG25-G/EG21-G modules in the compact and unified form factor. It contains 12 variants: EC21-A, EC21-V, EC21-AUT, EC21-AU, EC21-AUX, EC21-E, EC21-EU, EC21-EUX, EC21-EC, EC21-KL, EC21-J and EC21-IN. This makes it backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can easily migrate from LTE to 2G or 3G networks.

EC21 series 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 10/11, Linux and Android) extend the applicability of the module to a wide range of M2M and IoT applications such as smart metering, wearable devices, environmental monitoring, asset tracking, fleet management, smart safety and alarm systems.
