## Overview
Quectel EG91 is a series of LTE Cat 1 modules optimized especially for M2M and IoT applications. Adopting 3GPP Rel-11 LTE technology, it delivers maximum data rates up to 10 Mbps downlink and 5 Mbps uplink. These make the EG91 series an ideal solution for numerous IoT applications that are not reliant on high-speed connectivity but require the longevity and reliability of LTE network.

EG91 series contains 8 variants: EG91-NA, EG91-JP, EG91-VX, EG91-NAX, EG91-NAXD, EG91-E, EG91-EX, and EG91-AUX. The EG91 series is pin-to-pin compatible with Quectel GSM M95 module and LPWA BG95 series/BG96 modules. It is backward-compatible with existing GSM/GPRS and UMTS/HSPA(+) networks, ensuring that it can be connected even in remote areas devoid of 4G network coverage.

A rich set of Internet protocols, industry-standard interfaces, and abundant functionalities (USB serial drivers for Windows 8.1/10/11, Linux, and Android, etc.) 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.
