Quectel EC21 Series

IoT/M2M-optimized

LTE Cat 1 Module

Quectel EC21 is a series of LTE category 1 module opmized specially for M2M and IoT applicaons. It features cost-eecve,

low-power LTE connecvity, and delivers maximum data rates up to 10Mbps downlink and 5Mbps uplink. These make EC21

an ideal soluon for numerous IoT applicaons that are not reliant on high speed connecvity but sll require the longevity

and reliability of LTE networks.

EC21 is compable with Quectel UMTS/HSPA+ UC20/UC200T modules and mul-mode LTE Standard EC25/EC20 R2.0/EC20

R2.1/EG25-G/EG21-G modules in the compact and unied 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-compable with exisng EDGE

and GSM/GPRS networks, ensuring that it can easily migrate from LTE to 2G or 3G network.

EC21 supports Qualcomm® IZat™ locaon technology Gen8C Lite (GPS, GLONASS, BeiDou/Compass, Galileo and QZSS). The

integrated GNSS greatly simplies product design, and provides quicker, more accurate and more dependable posioning.

A rich set of Internet protocols, industry-standard interfaces and abundant funconalies (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 applicaons such

as smart metering, wearable devices, environmental monitoring, asset tracking, eet management, security and alarm

systems, and so on.
