Will 5G replace WiFi? Not in the short term

As global operators begin to pave the way for commercial 5G, the topic of 5G has also attracted more attention, and now an interesting point of view is: whether 5G will replace WIFI. Recently, both domestic and foreign operators have come up with a term - unlimited package traffic.

It is understood that major mobile operators in the United States have begun to provide unlimited data packages. Consumers will no longer need to switch back and forth between cellular networks and WiFi to avoid high data charges. Domestic operators are not far behind, China Unicom's Ice Cream Package, China Mobile's Apollo Package, and China Telecom's 4G Bangbo Card. Let's not complain about how "unlimited" these three unlimited packages are. This move has confirmed the direction of wireless mobile networks.

5G replaces WIFI: Impossible in the short term

WiFi has been around for 20 years and has spawned a nearly $20 billion market, including WiFi service providers and chip manufacturers, mainly because its technology is open and uses unlicensed spectrum to provide services. It is more convenient to use WiFi for short-distance transmission. Now almost all smart devices have WiFi modules, and most IoT devices are also equipped with WiFi modules. The export only uses a public IP address, and it doesn't matter if a large number of addresses are occupied within the LAN. It is very convenient for users to manage these devices under their own WiFi network.

5G and WiFi each have their own advantages. The advantage of 5G lies in its frequency band. Through low frequency band and carrier aggregation technology, the network capacity is greatly improved. The advantage of WiFi is its wide coverage, no need for wiring, and fast transmission speed. The wireless standard IEEE802.11a can reach 54mbps.

The speed of WiFi is also getting faster and faster, and now the wireless transmission speed can exceed 1000M. With the broadband speed increase and the continuous innovation of WiFi protocols, we will still connect to the WiFi network when we return home and enter the company, and it is a high-speed WiFi network. The 5G network will bring us a better user experience in the subway and outdoors. And it will play a better role in special fields such as telemedicine, Internet of Vehicles, mobile VR and other applications.
