The 4G gateway is a cost-effective 4G gateway product specifically developed for applications like automation, informatization, and the Internet of Things (IoT).

The 4G gateway offers functions such as serial-to-4G transparent transmission, edge data collection, timed data reporting, data change reporting, and remote control.

The module supports various serial fieldbus communication protocols downstream, including Modbus_RTU/ASCII, DLT645-97/07, S7-200 PPI (S7-Smart 485 interface) PLC, FX2N, FX3U, and more. Its compact design integrates a SIM card slot, IPEX (or SMA) antenna interface, USB configuration interface, and TTL (or RS485) communication interface, making it easy to embed into user instruments, controllers, and other PCBs.

On the upstream side, the module supports TCP, HTTP, MQTT, and other communication protocols, with data reporting in JSON format. It supports private cloud as well as cloud platforms like Alibaba Cloud, Huawei Cloud, Baidu Cloud, ThingsBoard, Airiot, EMQX, Mosquito, RabbitMQ, and MQTT Broker, enabling software developers to quickly build IoT data collection systems and informatization platforms.

The module also features remote management capabilities, allowing remote configuration and upgrades, reducing maintenance costs, and enhancing the user experience.
