# LTE EG21-G ## Summary - LTE Cat 1 module - 29.0 mm x 32.0 mm x 2.4 mm - 4.9 g - LGA form factor - Max. 10 Mbps downlink / 5 Mbps uplink under LTE - Extended temperature range of -40 °C to +85 °C ## Key features - Worldwide LTE, UMTS/HSPA+ and GSM/GPRS/EDGE coverage - Compatible with Quectel’s UMTS/HSPA+ module, and multi-mode LTE Standard EC2x series(EC25 series, EC21 series and EC20-CE)/EC200A series/EG25-G modules - Supports DFOTA and DTMF - Multi-constellation GNSS receiver available - USB 2.0 high-speed interface ## Overview Quectel EG21-G is an LTE Cat 1 module optimized specially for M2M and IoT applications. Adopting the 3GPP Rel-11 LTE technology, it delivers maximum data rates up to 10 Mbps downlink and 5 Mbps uplink. Designed in the compact and unified form factor, EG21-G is compatible with Quectel UMTS/HSPA+ module and multi-mode LTE Standard EC2x series (EC25 series, EC21 series and EC20-CE)/EC200A series/EG25-G modules, which allows for flexible migration among them in design and use. EG21-G is backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage. EG21-G supports Qualcomm® IZat location technology Gen8C Lite (GPS, GLONASS, BDS, Galileo and QZSS). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning. A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (USB serial drivers for Windows 7/8/8.1/10/11, Linux, Android) extend the applicability of the module to a wide range of M2M and IoT applications such as smart metering, wearable devices, environmental monitoring, asset tracking, fleet management, smart safety and alarm systems.
