Why are 5G routers so expensive? This problem is mainly due to the cost of materials (including chip systems), technology costs, design costs and a series of related costs of 5g routers, so 5g routers are expensive. But expensive is just an appearance. The high cost of 5g routers will eventually give you feedback on various aspects such as good signal stability, long-term stable operation of 5g routers, firmware upgrades to make up for loopholes, and improved service quality, so that you can surf the Internet more comfortably. Instead of the unstable restart of the router every three days and two ends, the signal is suddenly cut off and so on.
1. What is a 5g router
At present, the frequency band used by the general 150M router is 2.4HZ, and 5G is 5HZ, which is generally known as the Gigabit wireless router. In comparison, the advantage of the 5G frequency band is that it is more resistant to interference. The signal is more stable. Coverage is wider. The upper limit of the bottleneck of data transfer is higher.
2. Understand the characteristics of 5g routers, you can know why 5g routers are so expensive
2.1 Good anti-interference, due to the large signal energy of the 5G frequency band, but the weak coverage, that is, the coverage of a large room, the impact of passing through the wall is very large, which leads to less interference between mutual routers, and the use of the same There are different frequency bands for 2.4G router signals, so the signal is very stable.
2.2 The transmission speed is fast. If the home is a 100M broadband, after the router has turned on 5G, the mobile phone connection is measured by the speed measurement software, excluding the attenuation of the network cable signal and the attenuation of the wireless signal, the measured network speed can reach more than 10 megabits per second of download. And the 2.4G signal I measured was 4~6 megabytes. Of course, it has something to do with home broadband. If the broadband is more than 200 megabits, I believe that the 5G speed will be faster, and the 2.4G signal has already reached its peak.
2.3 There are requirements for equipment that receives transmissions. For example, some old mobile phones and laptop wireless receiving devices do not support 5G. Even if the router is turned on 5G, you will not be able to find its signal, and you need to purchase a dedicated wireless network card.
3. 5g routers are so expensive, is it necessary to choose 5g routers
First of all, the 5G WiFi of the router has nothing to do with the 4G/3G on our mobile phones, not an upgraded version of 4G. 5G WiFi is actually Wi-Fi using the 802.11ac protocol, which is the fifth generation technology.
Your bandwidth is equivalent to the performance of the car. The greater the bandwidth, the faster the speed of the car. 2.4GWIFI is equivalent to urban roads, which are more crowded, while 5GWIFI is equivalent to highways, which can increase the upper limit. But no matter how good the road is, if the car is not good, it is useless. So if you use 1M broadband, even 5G WIFI is not as fast as using 2.4G WIFI 100M broadband.
5G Wi-Fi was born to avoid the problem of mutual interference, because this frequency is currently used less. At present, in addition to some flagship mobile phones, most low-end mobile phones only support 2.4G.
4. Why are 5G routers so expensive and still the choice of many users
2.4G and 5G respectively refer to the transmission frequency of wireless routers. Among them, the 2.4GHz frequency is the most widely used, and is supported by almost all computer and smartphone devices.
However, because it is so common, when we turn on the wireless network card of the computer, we will see all kinds of strange Wi-Fi names of neighbors, and observation with special software will find that their frequency bands are seriously overlapping. Our current Bluetooth and wireless mouse transmitters, and even microwave ovens use the 2.4G band. The resulting problem is that severe interference will cause the data transfer rate to slow down.
5G Wi-Fi was born to avoid the problem of mutual interference, because this frequency is currently used less. At present, in addition to some flagship mobile phones, most low-end mobile phones only support 2.4G.
At the same time, routers that support 2.4G and 5G frequencies are more expensive than routers that only support 2.4G single frequency, and not many people use them at present. For example, it is like a newly built expressway, which is unimpeded because there are fewer vehicles on the road, while another 2.4G "old road" is already congested.
The higher carrier frequency also allows 5G Wi-Fi to carry higher transmission rates, which is the 802.11ac we will discuss later.
5. Reasons why 5G routers are expensive: Industrial 5G routers have high requirements
In the 5G era, the Internet of Everything came into being. The frequency band used by 150M routers is 2.4HZ, and 5G is 5HZ, commonly known as Gigabit wireless routers. In contrast, the 5G frequency band has the advantages of stronger anti-interference, more stable signal, wider coverage, and higher data transmission bottleneck. So what are the requirements for 5G industrial routers?
5.1 Normativeness of the communication interface
In the process of designing an industrial-grade 5G router, designers need to standardize the communication interfaces between the modular structures of the devices. Maintenance and updating of industrial grade 5G router modules and the addition of new modules should not affect other communication modules of the component. In addition, industrial 5G router software should have high fault tolerance, and generally minor software failures should not cause various serious system restarts.
5.2 Relative independence
The configuration data and processing programs in the design process of stable industrial 4G routers should be relatively independent, and any changes in configuration data should not cause changes in the running version of the device, so as to facilitate the compatibility of processing programs with any configuration data. In addition, industrial 5G routers should also be designed to prevent other procedures.
5.3 Device update
Industrial 5G routers are designed to change configuration data when increasing or decreasing a device's capacity, affecting normal communication simply by applying common human-machine commands. More importantly, industrial 5G routers should have the function of monitoring software operation failures. Once an industrial 5G router has a major failure such as an infinite loop, it should be able to automatically restart and issue a failure report immediately.
The industrial 5G router provides users with powerful edge computing performance, using ARM Cortex-A8 processor, 1GHz main frequency, up to 1GB DDR3 memory and 8GB eMMC FLASH. Provide computing resources for edge node data optimization, real-time response, agile connection, intelligent application, security and privacy protection, and effectively share the load of cloud computing resources.
Through the Python development platform, users can implement customized APP applications according to their own business. For a wide range of applications in the Internet of Things, the edge computing gateway is compatible with a variety of mainstream industrial real-time Ethernet protocols and industrial bus protocols, and supports the following protocols: Modbus TCP, Modbus RTU, OPC UA, PROFINET, PROFIBUS-DP, EtherCAT, EtherNET/IP, CC-LINK, PPI and other protocols.
The arrival of 5G means opening the door to the Industrial Internet of Things, and the characteristics of connected products will accelerate the emergence of new industry operators, thereby reshaping an industry. Unleashing huge possibilities for high-end manufacturing, telemedicine and driverless development.
