English: With the development of new communication technologies and continuous improvement of the network efficiency and functions of wireless communication, 4G has been widely used. 4G industrial-grade wireless routers are playing an increasingly important role in applications in various industries, and their prices are getting cheaper. Now there are a mixture of optional equipment on the market. How to choose one to ensure long-term use, stability and reliability, and The price is affordable. This is the question that customers think the most. Here is a brief explanation of the 4G industrial-grade wireless router.

Since the 3G era, 4G LTE networks have come a long way. It is not uncommon for 4G connections to have downlink throughput of tens of megabits per second and uplink throughput of several megabits per second. Even if these numbers are far below the theoretical 4G promise, the specifications are still impressive, provided that you may not be able to get similar speeds from a wired broadband connection, depending on your location.

Routers are generally classified into industrial grade and commercial grade according to different usage scenarios. What is the difference between the two? As the name suggests, the former is generally used in industrial occasions, and the latter is mostly used for commercial or household use. Specifically: Design process: 4G industrial-grade wireless routers have built-in high-performance communication modules, and commercial-grade designs are more common Stability: Industrial grade relies on reliable networking + stable communication, and the signal sensitivity is higher; commercial grade stability is often average, especially when it encounters thunder weather, it is easily affected Security: Industrial grade can use the VPN+VPDN private network channel provided by the operator to make data transmission more secure; commercial grade has lower security Application scenarios: Industrial grade can be widely used in smart transportation, security monitoring, environmental monitoring, power and water conservancy and other harsh external environments. Commercial grade is generally used in common use scenarios such as corporate offices and residential homes. Therefore, commercial grade cannot be used for industrial use, because industrial grade equipment has strict operating temperature requirements of -40 to 85°C. But industrial grade can be used in commercial scenarios, of course, the price is higher. Industrial networks generally have a single business, a complex electromagnetic environment, and extremely high reliability requirements. Every effort must be made to wire them. Only scenarios where reliability/real-time requirements are not high will see the existence of such things as CPE. Even in some occasions, WIFI devices are not allowed at all.

Industrial routers are a kind of use of public wireless networks to provide users with wireless data transmission functions. This is like we use mobile phone data to transfer things to another mobile phone or computer. The principle is the same, but the usage is different. At present, industrial routers have been widely used in the M2M industry in the Internet of Things industry chain. Such as smart grid, smart transportation, smart home, financial Internet of Things wireless communication router, mobile POS terminal, supply chain automation, industrial automation, smart building, fire protection, public safety, environmental protection, meteorology, digital medical treatment, remote sensing survey, agriculture, forestry , Water, coal, petrochemical and other fields.

If your goal is to use 4G routers in industry applications, such as branch backup connections, or as the main connection for drone room monitoring, then your 4G router needs to support some advanced features, including firewall, broadband binding, and application-centric Optimization. Ideally, you can use 4G industrial router functions in your main router, such as an SD-WAN router with broadband binding. In this setup, your line can fail over to a set of bonded 4G connections. Bonding two or more 4G wireless connections can not only provide wider bandwidth and higher throughput, but also provide self-healing functions for traffic on the 4G network. Imagine that you add another lane on the highway. Compared with single-lane expressways, two-lane expressways always win.
