Core skills of industrial wireless 4g routers

Industrial routers use public wireless networks to provide users with wireless data transmission functions.

Industrial-grade 4g wireless routers are mostly used for bus WIFI, automatic terminals, transportation, water conservancy, meteorology, Internet of Things, etc. The industrial-grade 4g wireless router is convenient, cost-saving, and solves the problem of difficult wiring in some projects. It has become more and more popular and has begun to be gradually promoted.

Core skills of industrial wireless 4g routers:

1. Throughput

Throughput is the packet forwarding capability of the core router. Throughput is related to the number of router ports, port speed, data packet length, data packet type, routing calculation method (distributed or centralized), and test method. 4g router manufacturers tell you that it usually refers to the ability of industrial router processors to process data packets.

2. Routing table capability

Routers usually rely on the establishment and maintenance of routing tables to determine packet forwarding. The routing table capacity refers to the limit on the number of routing table entries contained in the routing table. Since the core industrial routers that implement the BGP protocol on the Internet usually have hundreds of thousands of routing table entries, this project is also an important manifestation of the capabilities of industrial routers.

3. The ability of the bottom plate

The backplane refers to the physical path between the input port and the output port. The backplane capability is the internal implementation of the core router. Traditional core routers use a shared backplane. However, as high-performance industrial routers, they will inevitably encounter congestion problems. 4g router manufacturers tell everyone that the backplane capability can only be reflected in the design, and generally cannot be tested.

4. Packet loss rate

The packet loss rate refers to the proportion of data packets that the core router cannot forward due to insufficient resources under continuous and stable load. When an industrial router is overloaded, the packet loss rate is usually used to measure the performance of the core router. The packet loss rate is related to the length of the data packet and the transmission frequency of the data packet. 4g router manufacturers tell you that you can add route jitter or a large number of routes for testing and simulation.

5. Delay jitter

Delay jitter refers to delay variation. Data services are not sensitive to delay jitter, so this indicator is usually not an important indicator for measuring high-speed core routers.

In the Internet of Things industry: such as logistics and transportation, coal, agriculture, environmental protection, finance, meteorology, military and other fields, the data that needs to be collected is often in the wild or in an environment where it is difficult to lay a wired network. Therefore, for the transmission of data here, The wireless transmission function has a very powerful advantage over the wired transmission function.
