The common way of networking of industrial 4G routers will be achieved through WAN port or LAN port. Wireless WAN port plus 4G networking mode The network has two interfaces that can be connected to the wide area network (the WAN port of Ethernet port and the 4G port of the M2M network). The two channels form complementary and backup channels. At the same time, the WAN ports with Ethernet ports are connected to ensure the flow of data and save the traffic of 4G. When the WAN port appears abnormal, it cannot be connected to the wide area. When the network is used, the router can also connect to the server through the 4G network port, ensuring the integrity, reliability and stability of data. In this way of networking, Wireless WAN router
does not need to have any settings. When it is connected to the Internet cable, plugs in SIM cards with 4G traffic, and then it can work with power. In this way, the process of setting up of customers is reduced to the greatest extent. Also, the WIFI function of the router can work at the same time, which maximizes the number of users access to the LAN. This method is mainly applied to the high stability of the network. When the network is deployed, there are already existing WAN lines that can connect to WAN. And the data is required to have a backup line, such as factory buildings, intelligent buildings, smart cities and other related industries.
