What is a 4G industrial router4G industrial router is a high-speed industrial Internet of Things router, compatible with 4G/3G/2G networks, capable of high-speed and stable data transmission through 4G networks.4G/Cat-1/NB DTUGenerally, 4G industrial routers use industrial-grade high-speed 4G wireless communication modules, and are equipped with 32-bit high-performance processors. FLASH and RAM are doubled to increase the speed of wireless transmission of massive data. High-definition video, animation, pictures and other information that needs to be collected (such as pressure, temperature, flow, displacement, speed, electromagnetic, etc.) are transmitted more smoothly and at high speed.What is the difference between industrial routers and 4G ordinary routers?1. The stability of the products is different: the high stability performance of industrial cellular Industrial Router/Gateway is difficult to achieve with ordinary household routers. It takes a long time to work stably, and it can repair itself when the network fails. However, ordinary home routers cannot work for a long time, especially in outdoor situations, home routers with low security protection functions are prone to network outages.2. The requirements for the environment are different: the working range of a general home router is -10°C to 60°C, which can meet the needs under normal circumstances, but it cannot be applied to the industrial control field where the environment is harsher. Even in winter in the north, the general outdoor environment may not be used normally. Due to differences in components and designs, industrial-grade routers can reach a normal operating temperature of -35 to 75°C.3. Differences in hardware functions: general home routers only have RJ45 interfaces, which can only provide network for devices with network ports. In the field of industrial control, many devices have no network ports and only serial ports. These devices need to use industrial cellular routers with serial ports. In addition, industrial routers also need to be designed for industrial environments such as electromagnetic isolation, anti-static, and wide voltage, so that they have stronger anti-interference capabilities.4. Differences in software functions: general home routers can only provide common Internet access requirements, while industrial cellular routers need to be applied in different industrial control fields, so they need more functions suitable for industrial environment applications. Such as DMZ, static NAT, port forwarding, VPN, firewall, load balancing, watchdog, etc.
