5G and WiFi 6 are both wireless technologies that are used in wireless devices, but the difference between them is mobile communication VS WiFi Technology, or we can say, the difference between cellular network and WiFi technology on mobile phones. 5G for outdoor when WIFI 6 for indoor wireless.   Both technologies want to dominate each other, but they also help each other from time to time.

 

5G VS WIFI 6

A chart to know the difference between 5G and Wi-Fi 6

Spectrum type

Traditionally, cellular networks work on licensed spectrum and Wi-Fi works on unlicensed spectrum. But entering the 5G era, this division has gradually become blurred. On the one hand, some countries, such as Germany, UK, Japan, France, USA, etc., have allocated localized spectrum for 5G private networks, which can be used after enterprise applications are approved; On the other hand, NR-U defined by the standard is 5G wireless that works on unlicensed spectrum. From this trend, compared to previous generations, Wi-Fi 6 faces greater competitive pressure from cellular networks.
 

Mobility

Cellular networks are designed for mobility, and in this regard, they have natural advantages over Wi-Fi. But Wi-Fi can also support roaming between APs through the gateway, and support the expansion of WLAN to a larger coverage area. However, 5G has complete and mature mechanisms for reselection, handover, redirection, etc., while Wi-Fi 6 needs to be disconnected and reconnected, and roaming interruption time is longer.
 

Coverage area

Since the licensed spectrum allows higher transmit power, the coverage of 5G Small Cells is usually 100 meters to 300 meters, which is larger than the coverage of indoor Wi-Fi (usually within 50 meters)
 

Chip/terminal cost

The price of Wi-Fi 6 chip is cheaper than 5G, and the cost advantage is obvious.
 

Deployment cost

For wide-area coverage, 5G has the advantage of coverage capability, which can benefit the deployment of the original 2/3/4G site, and the deployment cost is lower than that of Wi-Fi. But for the enterprise LAN scenario, the cost of building a new 5G network and deploying terminal equipment is currently much higher than that of Wi-Fi. However, because 5G has more advantages in anti-interference, reliability, low latency, multiple connections, mobility, etc., for some services that require higher latency and reliability, such as automated control, it still needs to be deployed 5G private network. From a long-term perspective, it is believed that the deployment cost of 5G private networks will decrease, and once the cost drops to a sufficiently low level, it is believed that more companies will consider replacing some or all of Wi-Fi networks with 5G.

 

5G VS WIFI6

 

In general, 5G and Wi-Fi 6 are both competitors and complementary. At the same time, as technology and applications evolve and enter the era of 5G and Wi-Fi 6, the boundary between cellular networks and Wi-Fi is becoming increasingly blurred.
