Industrial 4g routers are mainly used in industrial, electric power, environmental protection, smart city and other environments, they may be used in station vending machines, bank numbering machines, parking lot gates, and community express cabinets. It can seen from this, industrial 4g routers are commonly used in public areas or factory production lines. And what kind of connection and difference does it have from ordinary home routers, industrial modems and switches?
The difference between industrial 4g routers and 4g routers
Similarity: Similarity is that both are routers, having routing functions. Both have WAN port, LAN port, 4G signal, SIM card slot. The 4G tariffs of the SIM card reflects 4G signal for networking, and then sends the wifi signal through the routing function so as to realize other devices' networking through the wifi signal. In technical terms, the route is automatically selected and set according to the signal, and sends the signal sequentially.
Difference: The difference between the two is that the application environment is different. Ordinary routers are mainly used in home or small business office environments, the working conditions are relatively stable. Industrial 4g routers may be used in underground, dams, oil fields, or at seaside, in relatively harsh environments. Therefore, it must have hardware protection such as power protection, anti-static electricity, lightning protection, etc., at the same time, it also has hardware watchdog without downtime for 24 hours.
If the commercial nature of the transmitted data is relatively high, which requires the encryption way to transmit, industrial 4g routers also support. Or use the VPN/APN virtual private network for data transmission, in this way, the transmission security is much higher than that of the ordinary router.
It can be obviously seen that the key difference between industrial 4g routers and ordinary home routers is in the application environment.
The difference between 4g routers and 4g modems
Similarity: The similarity that industrial 4g routers and industrial modems have is that that they are used in industrial environments. Both realize the wireless network data transparent transmission. They are also a device that meets networking needs for industrial projects. Usually both have hardware protection to provide the hardware foundation for continuous networking.
Difference: The difference between the two mainly comes from the shape and actual project application. Industrial 4g routers usually have a WAN port or a LAN port, some devices also have a serial port, for example, USR-G800 V2 has RS232 interface, suitable for project applications that require serial connection. It is mainly through the bus communication protocol conversion, set the terminal's IP address in advance so that networking can be realized. Realize the serial port to 4g network demand mainly through the dial-up form, if the interface in the project requires a serial port, it is suitable to use the modem device.
If it is distinguished from the terms of the actual project’s appropriateness, the industrial 4g router has better encryption transmission effect, suitable for applying in video surveillance, oilfield data monitoring, streetlight monitoring, etc. and dtu is suitable to be used in the environment where the transmission distance of the charging terminal, environmental monitoring, smart express cabinet and other field terminals are more dispersed.
The difference between industrial 4g routers and industrial switches
Similarity: The similarity that industrial 4g routers and switches have is that both are devices used to implement network data exchange, only the switch is used for the second-layer data exchange for the network data link layer, and the router is used for the third-layer device data exchange.
Difference: Industrial routers usually have less than 4 LAN ports, making instrumented networking through refracting wifi signals; the LAN port of the switch is usually less than 48, without the wifi module, mainly used to access wired devices. They have the difference in the principle(task hierarchy). The data exchanged by the network data exchange layer that the switch is in is relatively simple, when the industrial router performs data transmission, the protocol is rich, so the broadcast domain division of the two is also different.
