4G industrial routers typically refer to devices that use industrial grade design concepts and utilize 4G networks for data transmission. The product is equipped with a high-performance industrial grade communication processor and an embedded operating system as a software support platform.
The
4G Industrial Router system integrates communication protocols from the logical link layer to the application layer, supporting VPN, firewall, static/dynamic routing, PPP Server and PPP Client, DHCP Server and DHCP Client, etc. After being powered on, it can achieve autonomous dialing, automatically maintain communication paths, and ensure no disconnection; Support automatic scheduled online and offline functions.
The 4G
Industrial Router system is stable, equipped with an all metal casing, and has stronger anti-interference and radiation resistance performance. The product system comes with watchdog software and hardware protection to ensure 24-hour stable operation without downtime.
Classification of 4G wireless routers
4G routers can be divided into industrial 4G routers and commercial industrial grade 4G routers according to their purpose. From the perspective of WiFi LAN speed, 4G routers are further divided into 54M, 150M, 300M, etc.
Working principle of 4G
Wireless Router The 4G router mainly embeds wireless 4G modules into the original router. Firstly, users use a SIM card to plug in the 4G router and dial up the operator's 4G network WCDMA, CDMA2000, TD-SCDMA to achieve data transmission, internet access, etc. The router has WIFI function to achieve shared internet access. As long as the phone, computer, or PSP has a wireless network card or has WiFi function, they can access the internet through the 4G wireless router, It provides great convenience for realizing the sharing of 4G wireless networks in wireless local area networks. Some manufacturers also come with wired broadband interfaces, allowing for normal internet access without 4G. Through 4G wireless routers, broadband connections can be achieved, reaching or exceeding the current ADSL network bandwidth, becoming very widespread in applications such as office and travel or the Internet of Things.
The Function of 4G Wireless Router
4G routers are mainly used for 4G users' internet access and wireless coverage. Wireless routers can be directly connected to all Ethernet connected ADSL MODEM or CABLE MODEM, or can be re connected through LAN methods such as switches/hubs, broadband routers, etc. during use. It is equipped with a simple virtual dialing software that can store user names and passwords for dial-up internet access. It can provide automatic dialing functions for ADSL, CM, and other dial-up internet users without the need for manual dialing or occupying a computer as a server. In addition, wireless routers generally have relatively more comprehensive security protection functions.
At present, 4G industrial routers are mainly used in industries such as smart transportation, intelligent monitoring, water conservancy and environmental protection, power data monitoring, postal systems, meteorological monitoring, and mobile Internet of Things.
