The principle and use of 4G wireless router

The industrial-grade router is a small industrial-grade wireless router with a single LAN port and a classic industrial-grade design, which is easy to achieve smart, safe, reliable and stable wireless communication requirements. TDD/FDD-LTE, 4G, 3G networks are optional. So what is the difference between 4G wireless routers?

　　 What is the difference between a 4G wireless router?

1. The first is to use the USB interface provided by the device with USB and 4G network cards. It can be used by sharing, 4G network card data services to realize multiple computers sharing the Internet, especially suitable for some inconvenient access to fixed broadband or needs The principle of wireless router setting for mobile users who share the Internet.

　　2. The second type can support access to wireless broadband through the unique wireless WAN port function. That is, in some Wi-Fi urban hotspots, when the ISP's wireless broadband signal is not very strong, the wireless WAN port function can be used to achieve wireless signal amplification and multi-machine sharing Internet access without plugging in the cable. The principle of wireless router setting .

　　3. The third is to support ordinary broadband access by providing WAN interfaces, such as supporting traditional DSL and Cable broadband access. It also has super compatibility, can break through some areas with access, and easily realize multi-machine sharing Internet. In addition to supporting multiple access methods, it also supports a variety of practical functions, such as supporting WDS function, which can wirelessly bridge several wireless devices. Router, expand wireless network coverage. Support QoS bandwidth control function, which can effectively control the download rate of each client. At the same time, a "one-key setup" CD developed for non-professionals is also distributed, allowing you to easily install the router and quickly surf the Internet.

What is the principle of 4G wireless router:

After the 4G network card receives the 4G signal, the 4G wireless router converts the signal into a WLAN signal that can be wirelessly received by the notebook. At the same time, it can also be connected to the computer through the LAN port of the 4G router with a network cable, so that it can be realized by the router function Multi-machine sharing 4G Internet access.

　　Industrial-grade 4G routers are generally more stable than civilian-grade 4G wireless routers on the market, and are more adaptable to continuous work in harsh weather conditions, and at the same time, the cost is higher. It is currently widely used in the M2M industry in the IoT industry chain, such as smart life, smart grid, smart transportation, industrial automation, smart buildings, public safety, environmental monitoring, smart agriculture and other fields.

　　The use of industrial routers

1. In terms of high forwarding performance and high bandwidth, most of the industrial-grade routers are used for data transmission and other functions, and there are hundreds of them. If you want to meet the wireless Internet needs of so many people at the same time, the router's forwarding There are high requirements for performance and bandwidth, and home routers have low density, low signal strength, small coverage, and limited forwarding performance and bandwidth.

　　2. Functional positioning: Industrial-grade routers have superior performance in this regard, and can satisfy more people with high-speed Internet access. Most industrial-grade routers use high-frequency network dedicated processors, with strong data processing capabilities, longer transmission distances, and larger coverage areas, which can greatly increase the transmission speed and throughput of the network, and the operation is also very stable.
