In the past six months, the news of 5G network has emerged one after another. The 5G commercial license has been officially issued, and the three major operators have indicated that they will cover at least 40 cities by the end of this year, as well as the latest bidding results of China's 5G network. At a time when people showed the greatest enthusiasm for 5G, WiFi6 was born.

Competition and Mutual complement between 5G and WiFi6

In 2019, carrier-based mobile connections (LTE and 5G cellular networks) and unauthorized wireless networks (WiFi6, or 802.11ax) will be close to each other in two main aspects: radio signal coding and resource scheduling. Both wireless systems use the same method to enable each base station or wireless access point to communicate with more devices at the same time. Although the methods used in technology are the same, there are still differences in cost, infrastructure layout and management control for enterprise networks between wireless systems based on operators and unauthorized wireless systems.

In the future, WiFi6 and 5G may change their roles because of their high speed and high bandwidth. With the launch of 5G and WiFi6 in 2019, the world of the Internet of things is quietly changing. Internet of things devices will transmit more information with the least energy consumption. The less energy is consumed, the longer the devices will be used, which is more beneficial to people's lives.

Both WiFi6 and 5G adopt scheduling methods that make resources more deterministic, which is also important for mission-critical Internet of things assets used in automated manufacturing, healthcare, energy, and other industries. In the future, WiFi6 wireless access points will add support for other radio technologies (such as Bluetooth and Zigbee), which will become more powerful Internet of things gateways and even serve as useful wireless sensors to help track and manage devices. It is worth noting that, as an extension of LTE technology (and subsequent 5G technology), CBRS (Citizen Broadband Radio Service) is said to be a complementary technology to WiFi6 to provide wireless connectivity within the building.

Compared with WiFi6, 5G technology also has its own advantages. For enterprise IT, in areas where WiFi is not an ideal choice, 5G will be a revolutionary technology. For example, if there are hundreds or even thousands of Internet of things devices that need to be connected wirelessly, WiFi6 will be a necessary wireless technology to connect Internet of things devices in their own buildings. When the Internet of things is transferred to an area outside the enterprise building, the sensor can still use 5G as the wireless transmission mode to obtain a connection with sufficient speed and reliability. 5G and WiFi6 have made Internet of things devices "alive" and changed the way we use Internet of things devices.

All in all, the possibility of 5G replacing WiFi is not high, on the contrary, WiFi will continue to evolve and upgrade through 5G technology. For quite a long time in the future, 5G and WiFi6 will coexist and complement each other, and they have great application potential and imagination space in industrial production, Internet of things, intelligent driving and many other fields, helping various industries to break out new productivity.
