Product Description
Product Overview
Brief introduction
This router is an industrial IoT communication device that is fully compatible with 5G/4G/3.5G/3G/2.5G networks. It features industrial grade protection, wide temperature, and wide voltage design, making it easy to build high-speed and stable wireless transmission networks. Provide wireless long-distance data transmission services to users using public NR, LTE networks (or VPDN proprietary networks).
This router adopts a high-performance industrial grade 32-bit dual core communication processor and industrial grade communication module, with an embedded real-time operating system as the software support platform. It also provides 2 RS232/485, 1 Ethernet LAN, and 1 Ethernet WAN interface, which can simultaneously connect serial port devices and Ethernet devices to achieve transparent data transmission and routing functions.
Application area
Industries that require remote data transmission, such as industrial control, electricity, petroleum, coal mining, finance, communication, public security, heating, meteorology, water conservancy, transportation, and municipal services.
