Quectel EC21-A LCC Module is LTE Cat 1 module optimized specially for M2M and IoT applications delivering maximum data rates up to 10 Mbps downlink and 5 Mbps uplink
Quectel EC21-A LCC Module Product Overview
Quectel EC21-A LCC Module is a LTE Cat 1 module delivering maximum data rates up to 10 Mbps downlink and 5 Mbps uplink. It is optimized specially for M2M and IoT applications featuring cost-effective, low-power LTE connectivity making it 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+ UC200T series modules and multi-mode LTE Standard EC25 series/EC20 R2.1/EG25-G/EG21-G modules in the compact and unified 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-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can easily migrate from LTE to 2G or 3G network.
