The EG91-EX from Quectel is a LTE Cat 1 Module that supports 3GPP Release 11 LTE technology. It delivers an uplink data rate of up to 5.76 Mbps and a downlink data rate of up to 42 Mbps. This module is backward-compatible with existing GSM/GPRS and UMTS/HSPA+ networks and hence can be connected even in remote areas devoid of 4G network coverage. It is designed for use in the EMEA region and also supports GPS, GLONASS, BeiDou, Galileo and QZSS GNSS constellations. This module supports eCall, (U)SIM, DTMF, QMI/RmNet, QuecLocator® and QuecFile features. It has echo cancellation & noise suppression arithmetic features and supports Digital Audio & VoLTE.
The EG91-EX requires a DC supply of 3.8 V and has an embedded power management unit (PMU) that enables ultra-low deep-sleep current consumption. It can be controlled via UART, USB 2.0, I2C, SPI and PCM interfaces. This module is available in an LGA package that measures 29.0 x 25.0 x 2.3 mm and is ideal for M2M and IoT applications such as smart metering, wearable devices, environmental monitoring, asset tracking, fleet management, security and alarm systems.
