# LTE EG21-G Mini PCIe ## Summary - LTE Cat 1 module - 51.0 mm x 30.0 mm x 4.9 mm - 9.8 g - Standard PCI Express® Mini Card form factor (Mini PCIe) - Max. 10 Mbps downlink / 5 Mbps uplink under LTE - Extended temperature range of -40 °C to +80 °C ## Key features - Worldwide LTE, UMTS/HSPA+ and GSM/GPRS/EDGE coverage - Supports DFOTA and DTMF - Multi-constellation GNSS receiver available - USB 2.0 high-speed interface ## Overview Quectel EG21-G Mini PCIe is an LTE Cat 1 module adopting standard PCI Express® Mini Card form factor (Mini PCIe). It is optimized specially for M2M and IoT applications, and delivers maximum data rates up to 10 Mbps downlink and 5 Mbps uplink. EG21-G Mini PCIe 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 Mini PCIe 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 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 applications such as smart metering, wearable devices, environmental monitoring, asset tracking, fleet management, smart safety and alarm systems. ## Product Brochure [Download](https://www.quectel.com/content/uploads/2026/05/Quectel_Product_Brochure_V8.6.pdf) ## Documentation and resources -
