Quectel EC21 is a series of LTE category 1 module optimized specially for M2M and IoT applications. It features cost-effective,
low-power LTE connectivity, and delivers maximum data rates up to 10Mbps downlink and 5Mbps uplink. These make EC21
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 is compatible with Quectel UMTS/HSPA+ UC20/UC200T modules and multi-mode LTE Standard EC25/EC20 R2.0/EC20
R2.1/EG25-G/EG21-G modules in the compact and unified form factor. It contains 10 variants: EC21-E, EC21-EU, EC21-EUX,
EC21-A, EC21-V, EC21-AUT, EC21-AU, EC21-AUX, EC21-KL and EC21-J. 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 supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BeiDou/Compass, 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, Linux, Android/eCall*) 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, security and alarm
systems, and so on.
