The EC21 is an LTE category-1 module optimized specially for M2M and IoT applications. It delivers power-enhanced performance and M2M-optimized speeds of 10Mbit/s downlink and 5Mbit/s uplink, and features low-power, low-cost LTE connectivity. These make it ideally suitable for numerous IoT applications that are not rely on high speed connectivity but still require the longevity and reliability of LTE networks.
EC21 is fallback compatible with UMTS/HSPA+ UC20 module and multi-mode LTE EC20 module in the compact and unified form factor. EC21 contains 5 variants: EC21-V, EC21-A, EC21-E, EC21-AUT, and EC21-AUTL. This makes it backward compatible with existing EDGE and GSM/GPRS networks, which ensures that it can easily migrate from LTE to 2G or 3G networks.
A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB drivers for Windows XP, Windows Vista, Windows 7, Windows 8/8.1, Linux, Android/eCall) extend the applicability of the module to a wide range of M2M and IoT applications such as metering, wearable devices, digital signs, industrial routers, tracking and tracing, fleet management, smart home gateways and even drones.
