Classification of enterprise 4g modem router with ethernet port
There are many types of 4G modems routers with ethernet port, which can be divided into different categories from different perspectives. Different types of 4G industrial routers can be used in different environments. The following sections classify the 4G industrial routers from different perspectives.
According to the structure of the points
The 4G industrial router can be divided into modular router and non-modular router according to the structure Angle.
Modular routing generally only provides basic routing function when leaving the factory. Its interface type and partial extension function are configured according to the actual needs of users. Users can choose corresponding modules according to the network type they need to connect. Different modules can also provide different connectivity and management capabilities. For example, the vast majority of modular routers allow users to choose network interfaces, VPNS, firewalls and other functions, most of which are modular routers.
Non-modular routers are mostly low-end routers, which are mostly used in civilian environments. Primarily used to connect small business customers within homes or isps, supporting virtual private network protocols such as SLIP, PPP, PPTP, and IPSec. These protocols to run on each port, such as ADSL will increase home broadband availability, which will increase the burden of accessing routers. In the future, such router ports will run multiple protocols while avoiding the telephone switched network.
According to the interface points
4G industrial routers can support SDH stm-1 interface, SDH stm-4 interface and SDH stm-16 interface. At present, the router supporting SDH stm-64 interface is high-end 4G industrial router. However, other interfaces are relatively weak, among which stm-1 has two types of optical interface and electrical interface. Stm-1 electrical interface is suitable for local situations where the interference signal is weak. The light interface is usually used for stm-4, stm-16 and stm-64.
