Overview
GM191 is a wireless communication module based on LTE Cat.1 standard and designed for M2M and IoT applications, compatible with GosuncnWelink 4G LCC module 30x30mm package.
Under the LTE standard, it can support up to 5Mbps uplink rate and 10Mbps downlink rate and can be backward compatible with existing GSM (EDGE and GPRS) networks, ensuring that it can work normally in remote areas lacking 3G and 4G networks. Satisfy customers' application requirements for high-cost performance and low power consumption, especially suitable for occasions that do not require high network speed but require stable and reliable LTE network connection..
GM191 module supports multiple network protocols (TCP / UDP / FTP / HTTP/FILE*/MQTT*/SSL*) and multiple functions (remote wake-up, WeFOTA, multiple APN, multiple sockets, serial port transparent transmission, WelinkOpen, etc. ), support dual SIM card, dual standby, VoLTE.
GM191 can be widely used in industries such as smart data transmission, wearable devices, POS, industrial control, asset tracking, POC, and shared terminals in the M2M and IoT fields.
