1. An Analysis of 4G Industrial Routers
The 4G industrial router supports all networks of China Mobile, China Telecom, and
China Unicom's 4G/3G/2G networks. It is an IoT wireless communication router that
uses public wireless networks to provide users with wireless long-distance data
transmission capabilities.
The product uses a high-performance 32-bit embedded processor, built-in complete
TCP / IP protocol stack, while providing RS serial and 10/100M Ethernet interface.
Integrated IO terminal block provides serial or GPIO interface. The serial ports
provide transparent transmission modes of RS-232, RS-485, and TTL level interfaces
respectively. The embedded real-time operating system is the software support
platform. The system integrates a full range of communication protocols from the
logical link layer to the application layer, supporting VPN (Including PPTP+L2TP and
IPSEC+GRE), static and dynamic routing, DHCP server and DHCP client, DDNS, firewall,
WEB configuration, APN/VPDN support, auto-dial on power-up, automatic
maintenance of communication link, and link always online, support automatic timed
and offline functions and other functions.
The product has a patented technology that maintains the system's stability, ensuring
that the equipment is always on-line; the whole machine adopts a metal shell,
anti-jamming and radiation protection; the hardware adopts industrial-grade design;
the system is equipped with a watchdog WDT protection; the whole product passes
the European CE certification, through the electric 3000V electric shock test, all
wireless modules have passed FCC certification or CE certification; after rigorous
design, testing and practical application of 10 years, the product performance is
stable and reliable.
Products access test through the telecommunications M2M platform, mobile M2M
platform access testing. Has been widely used in the M2M industry in the Internet of
Things industry chain, such as smart grid, intelligent transportation, smart home,
finance, mobile POS terminals, supply chain automation, industrial automation,
intelligent building, fire protection, public safety, environmental protection, weather,
digital Medical, remote sensing, agriculture, forestry, water, coal, petrochemical and
other fields.
The basic functions are stable and reliable
1. Online maintenance of patented technology: intelligent anti-drop, online detection,

2. online maintenance, dropped automatic redial, abnormal automatic reset, ensure
that the device is always online.
2. Serial ESD protection: Serial RS232 built-in 15KV ESD protection.
3. Metal shell: metal shell, radiation protection, anti-jamming; shell and system
safety isolation, lightning protection design; in line with electrical safety
requirements; protection class IP30; especially suitable for harsh industrial control
areas.
4. All wireless modules have FCC or CE certification.
5. Large memory: There is a large memory to cache the data sent by the client, while
receiving large data packets, the data is not lost.
6. Perfect protocol stack: The new system loads a perfect TCP/IP protocol stack and
adopts a complete TCP/IP protocol stack; it has excellent network communication
performance and greatly reduces the probability of dropped calls.
