Industrial 4G Smart Gateway

The 4G Smart Gateway designed for industrial environment, is equipped with quad-core 64-bit processor RK3308B dedicated to IoT. It fully supports 4G LTE, NB-IoT, and LoRa communications, and has dual 100M Ethernet ports, RS485, CAN, RS232 interfaces; it also supports Chinese commercial cryptography algorithms. The smart gateway can be widely used in industrial fields such as industrial 4G routers, IoT, and automation systems.

Low-power quad-core IoT processor

Rockchip RK3308B IoT processor, with quad-core 64-bit Cortex-A35 core and main frequency up to 1.3GHz, is high-performance and low-power. Compared with the traditional IoT processor’s Soc architecture, this processor is smaller, with the power consumption reduced by 32% while the efficiency increased by 25%.

Wireless communication support

The smart gateway supports 4G LTE Cat1 wireless communication module, which can realize seamless connection to any operator's 4G network. Supporting NB-IOT communication, global frequency band B1/B3/B5/B8/B20/B28 and so on, it is fast and low-power. It also supports industrial-grade long-distance LoRa communication at 868MHz, and the outdoor line-of-sight communication distance is up to 8km, featuring long-distance communication and high stability, etc.

Dual RJ45 Ethernet Ports

Dual RJ45 Ethernet ports with speed up to 100Mbps, are suitable for industrial control equipment, industrial control and other uses.

Abundant interfaces

It provides multiple communication interfaces like RS485, CAN, RS232, and provides relay and opto-isolator I/O, which can meet the needs of different applications.

MQTT protocol supported

Modbus standard industrial protocol to MQTT protocol is possible; Alibaba Cloud and other private cloud are supported. The smart gateway is suitable for IoT PLC data acquisition and equipment control.

Chinese commercial cryptography algorithms

The onboard PSAM card slot is convenient for the system to integrate the PSAM card. It has type approval, powerful data encryption and decryption functions — providing excellent-performance DES/3DES, AES, SHA, RSA, ECC, and Chinese commercial cryptography algorithms SM1/SM2/ SM3/SM4 and others.
