WiFi (including WiFi6) has limited coverage, but it undertakes most of the data traffic of mobile terminals such as mobile phones and tablet computers. Although the mobile communication network (including 5G) covers a wide range, its cost is high (a large number of base stations and computer rooms are needed, and the maintenance cost is high and the power consumption is high). The data flow of mobile communication network is mainly used in outdoor mobile environment.
5G is the fifth generation wireless communication technology, the latest generation cellular mobile communication technology and the extension of 4G system. The performance goals of 5G are high data rate, low latency, energy saving, low cost, high system capacity and large-scale equipment connection. WiFi6 is the sixth generation wifi technology, also known as 802. 1 1ax. As the latest WiFi standard, it can provide higher transmission speed, lower delay time and greater device density.
Therefore, there are still essential differences between 5G and WiFi6. WiFi6 only needs to bring a WiFi6 router to connect to the home broadband, and 5G needs to use the SIM card of the mobile operator to charge according to the traffic. Speed comparison between 5G and WiFi6 In the middle of 20 19, network equipment manufacturers officially launched WiFi6 router products. At present, flagship machine, a major mobile phone manufacturer, has started to support WiFi6 as standard. The theoretical maximum rate of WiFi6 is 9.6Gbps, which is difficult to achieve in practice. ?
Since the 20 19 Ministry of Industry and Information Technology issued the 5G license, the 5G base stations of China Mobile, China Unicom and China Telecom have achieved 5G signal coverage in more than 50 key cities. The theoretical uplink peak transmission rate of 5G is 10Gbps, and the theoretical downlink peak transmission rate is 20Gbps, which is difficult to realize in practice.
In practical applications, the speeds of 5G and WiFi6 are basically the same. The speed of 5G will be limited by the distance and the number of users using the same base station, and the speed of WiFi6 will be limited by the broadband network speed accessed and the number of terminals connected to the same WiFi. WIFi6 and 5G are both expected new wireless connection methods. These two technical support supplements can help improve the data transmission rate (which is conducive to supporting new applications) and network capacity (which is conducive to connecting more devices).
The difference between 5G and WiFi6 application scenarios From the perspective of the improvement of network speed and capacity, both 5G and WiFi6 can bring better outdoor Internet experience. However, in terms of specific usage scenarios (for example, in a car speeding on a high-speed railway fire highway with a speed of more than 300 kilometers per hour), 5G is undoubtedly the first choice for wireless Internet access.
WiFi6 is very suitable for indoor wireless networks (such as home, business hall, office, conference center, etc.). Its deployment, maintenance and expansion costs are also kept at a reasonable level, at least you don't have to worry about running out of traffic.
To sum up, there is no need to separate 5G from WiFi6. Each of them has its own application scenarios. For a long time to come, 5G will coexist with WiFi6*** and complement each other. 5G and WiFi6 will have great application potential and imagination in many fields such as industrial production and Internet of Things.
