What is a 4g industrial router?
4G industrial router is an IoT communication and networking device that provides fast networking solutions for user equipment through the 4G LTE cellular network. Usually 4g industrial routers use high-performance embedded CPUs with operating frequencies as high as 580MHz or more. Based on a variety of hardware interfaces and powerful software functions, users can quickly build their own application networks. 4G industrial router is also a relatively mature networking device in relatively mature industrial projects. It has been widely used in the M2M industry in the Internet of Things industry chain, providing Reliable solutions for smart grids, personal medical care, smart homes, self-service terminals, industrial automation and other fields. Data transmission networking.
The reason why 4G industrial routers are called “industrial” routers is different from home routers. Its difference is reflected in: it ensures normal communication work in severe cold and hot environments, and provides hardware protection functions such as electromagnetic isolation, anti-static, anti-surge, and anti-interference. It can adopt complex network topology, load sharing and optimal path. A simple classification is as follows:
Different stability: Industrial routers usually provide a stable network environment for data transmission in industrial communications. For example, they have built-in watchdog protection to ensure stability and no downtime 7×24 hours. Data loss due to network failure may cause losses to the entire project . Generally, home routers cannot achieve the working status of the trial set. Especially in outdoor environments, home routers are prone to network disconnection.
The usage environment is different: the industrial environment is complex and diverse, and stable work must be carried out in the four seasons of severe cold and heat, or water conservancy projects need to prevent surges, or underground surveys, or interference caused by high- voltage power environments, etc. The components of industrial routers are different in design from home routers and can ensure stable networking in environments ranging from -35 to 75°C.
Different hardware protection: In the field of industrial networking, usually industrial routers are devices with serial ports or connected to network ports to serial ports to adapt to the serial port devices on the project. There is a lot of interference in the outdoor networking environment. In addition to the high-performance CPU embedded in the components and the precise circuit design, the 4G industrial router also has a metal shell that can shield electromagnetic interference and prevent radiation. At the same time, circuit protection includes EMC electromagnetic compatibility protection, ESD anti-static design, EFT anti-pulse and other hardware protection. Home routers usually have stable operating temperatures and a superior environment, so they do not need this type of hardware protection and can also complete networking functions.
Different software functions: The need for home routers is to achieve ordinary networking, while home routers usually only have networking functions. Some home routers may also come with security functions such as firewalls.In addition to networking functions, 4G industrial routers must have static routing , port forwarding, VPN private network transmission, load balancing, peanut shell intranet penetration, dynamic domain name resolution, remote management and other functions to meet the needs of industrial sites.
