Communication and function between 5G industrial router and remote computer
The main function of 5G industrial routers is to transmit data. The transmission distance of industrial routers determines the performance of their products. Rational use of industrial routers to maximize the transmission distance. Therefore, it is necessary to understand the factors affecting the transmission distance of industrial routers.
I. Communication between 5G industrial router and remote computer:
1. First, the LAN is connected to the power supply through network cables. When the network port device connects to the industrial router, wifi connects to the LAN port. The industrial router connects to the external network through network cables.
2. When a network port device is connected to an industrial router, the industrial router is connected to the same LAN and computer. The computer terminal to be controlled is also connected to the LAN through WIFI or network cable.
3. Port mapping on an industrial router Map WAN ports and IP addresses to LAN ports.
4. After port mapping is complete, the network port device functions as TCPSever and the computer functions as TCPClient. In this case, the IP addresses of the network port device and computer are on the same LAN of the extranet, so that the network port device and computer can communicate on the same LAN.
5. But in life, we seldom use the same LAN transmission applications, usually we use more remote communication.
6. For example, if I have a network port device at home and a computer in the company, how can I control the network port device at home (such as the home computer)?
7. 4G iot network card is needed to connect industrial routers through private network communication by setting up VPN network port devices (home computers).
8. The next step is to set up an industrial router to connect to the remote VPN network. The WAN port of the industrial router is also mapped to the LAN port, and the PC end of the company is connected to the VPN simultaneously.
II. Functions of wireless client of industrial router:
Wi-Fi bridging, which can be understood as a small trunk function, is not exactly equivalent to the trunk function. For example, in the exportation environment, the external link wifi radiation is within 1 km, but within 1 km.5 km away, there is a network device that wants to connect to the exportation network port. In this case, the industrial router can be placed between the extranet and the network-network device to meet the networking requirements of network-network devices.
