Quectel EC21
IoT/M2M-optimized LTE
Cat 1 Module
Build a Smarter World
Quectel EC21 is a series of LTE category 1 module opmized specially for M2M and IoT applicaons. It features cost-eecve,
low power LTE connecvity, and delivers M2M-opmized speeds of 10Mbit/s downlink and 5Mbit/s uplink. These make EC21
an ideal soluon for numerous IoT applicaons that are not reliant on high speed connecvity but sll require the longevity
and reliability of LTE networks.
EC21 is compable with Quectel UMTS/HSPA+ UC20 module and mul-mode LTE EC20/EC25 module in the compact and
unied form factor. It contains 9 variants: EC21-E, EC21-A, EC21-V, EC21-AU, EC21-AUT, EC21-AUV, EC21-J, EC21-KL and
EC20-CEL. This makes it backward-compable with exisng EDGE and GSM/GPRS networks, ensuring that it can easily
migrate from LTE to 2G or 3G networks.
EC21 supports Qualcomm® IZat™ locaon technology Gen8C Lite (GPS, GLONASS, BeiDou, Galileo and QZSS). The integrated
GNSS greatly simplies product design, and provides quicker, more accurate and more dependable posioning.
A rich set of Internet protocols, industry-standard interfaces and abundant funconalies (USB drivers for Windows XP,
Windows Vista, Windows 7/8/8.1/10, Linux, Android/eCall) extend the applicability of the module to a wide range of M2M
and IoT applicaons such as smart metering, wearable devices, environmental monitoring, asset tracking, eet management,
security and alarm systems, and so on.
