What is the difference between industrial router and switch
With the continuous development of the Internet of things industry, the development of industrial routers is also popular all the way, but many people do not know what is the difference between it and the switch. Let's let the small edition of miaoerqiao technology explain it to you.
1、 Different appearance
The port of industrial router is wan / LAN only, but it is connected through cellular network and refracts WiFi signal. It needs to expand the coverage range of the signal, so its antenna has 5 DBI full frequency rod antenna, WiFi uses 3 DBI high gain antenna, it can also choose full frequency rod antenna for signal external connection, and the signal is more stable.
The switch port is mainly to expand the network and access more networking terminal equipment, so there are many LAN ports, ranging from 8 to 16. There are even 24 port or 48 port switches on the market. At the same time, due to the use of wired networking, it does not need to be used with the antenna.
2、 Different functions (different application scenarios)
Industrial Router: it is used for indirect network, which can connect different networks. At the same time, it is commonly used in outdoor parking lot, intelligent water conservancy, industrial oil field and underground monitoring, pollution source field monitoring, security wireless video monitoring and other projects.
And the switch is just to expand the LAN access point, so that more terminals can realize networking, usually in indoor convenient wiring projects. For example, unattended computer room, building distribution box and other application scenarios.
3、 Different network processing
The industrial router can automatically assign IP and virtual account to LAN; the network layer supports "TCP / IP" protocol, which deals with IP address addressing; the network layer supports "TCP / IP" protocol, which deals with IP address addressing; the network layer supports "TCP / IP" protocol, which deals with IP address addressing; the network layer supports firewall, which guarantees the safe passage of data.
Switch: it is only used to allocate network data; it can only address according to "Mac" address in relay layer; and it does not support firewall.
These are the three major differences between industrial routers and switches, hoping to help you.
