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 10 Mbps downlink and 5 Mbps 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+ UC200T series modules and mul-mode LTE Standard EC25 series/EC20 R2.1/
EG25-G/EG21-G modules in the compact and unied form factor. It contains 10 variants: EC21-A, EC21-V, EC21-AUT,
EC21-AU, EC21-AUX, EC21-E, EC21-EU, EC21-EUX, 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, 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) 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.
