Industrial router is a kind of communication equipment of Internet of Things, which can be divided into 2G router, 2.5g router, 3G router 4G router and 5G router according to network type. Because industrial routers use the network provided by the operator for dial-up networking, they can be used wherever the operator's network covers them.
How does an industrial router work? Users can communicate with the Internet by setting up a default gateway on a PC or network device. In fact, the default gateway set up on network devices is the exit of network devices' packets. As long as the packets are sent to the Ethernet port of the router, the next work is done by the router, so it can be said that the router is the relay station of the Internet.
So how do routers forward packets? It's like if you're going somewhere, you need to schedule a route, and that route is the routing table. The routing table contains all the destination network addresses that the router knows and the best paths to those networks through the router. Due to the existence of routing table, the router can carry out packet forwarding based on it, so this is the working principle of the router.
Industrial routers in the IoT Industry: At present, industrial routers are mainly used in the Internet of Things industry, such as electric power, water conservancy, transportation, finance, agriculture, forestry, coal mine, petrochemical industry , environmental monitoring and protection, meteorology, fire protection, public safety, smart home, automation and other fields.
