Will 5G End WiFi
Dec 24, 2018

With the arrival of 5G, will WiFi still exist?


The first thing to be clear is that 5G is a licensed band technology, and WiFi works in an unlicensed band, so WiFi does not require huge spectrum usage fees. The design concept of WiFi is simple and versatile, but due to the large amount of interference in the unlicensed band, WiFi only provides best-effort services.


Secondly, with the development of mobile networks, WiFi technology is constantly being updated, penetration is stronger, and wider coverage of WiFi technology is emerging. With the continuous development of technology, WiFi is being applied to all aspects of society with unique ideas. For example, on an airplane, the airline provides WiFi access to passengers; in high-speed trains, the railway company can also provide passengers with secure high-speed WiFi Internet access.


In addition, the flexibility and low cost of WiFi makes it one of the most important access methods in the 5G phase. The 3rd Generation Partnership Project (3GPP) is also discussing the convergence of 5G and WiFi. In the end, when the user comes indoors from the outdoor, the user can switch from 5G network to WiFi network smoothly and without perception.


In the future, with the development of the Internet of Things, the network is required to be “always on/always connected”. WiFi may even be combined with the Internet of Things to complement the 5G to complete the seamless connection of “always on/always connected”.


Therefore, the arrival of 5G will not end WiFi.
