The WiFi Alliance has officially announced its certification program for the next-generation networks aka WiFi 6. As you might know, the WiFi Alliance now uses a more understandable naming convention when referring to its standards.
So, WiFi 6 represents the WiFi standard 802.11ax and it can provide better latency and more theoretical download speeds, around 4 times higher than the current fastest WiFi-AC (WiFi 5). So, it could be more than 10Gbps, however, using the same in the real world would be lesser.
Among the various technical improvements, WiFi 6 now mandated the use of the newer WPA3 security protocol which was released to fix some big loopholes in WPA2.
As you might know, the older WiFi AC only works with the 5GHz band, although, it offers gigabit speeds. WiFi 6, on the other hand, is designed to work from 1 GHz to 6 GHz. However, for the users, it gives more flexibility by adding support for the 2.4GHz band.
Operating on higher frequency bands does improve theoretical speeds but it also reduces the range of the WiFi network at the same time, making it difficult to penetrate through walls. That’s where the 2.4Ghz turns out to be helpful.
WiFi 6 is better at simultaneously transferring data to a large number of users. Furthermore, it uses TWT (target wake time) to improve battery life in WiFi devices including IoT (Internet of Things).
Speaking of WiFi-enabled devices, there aren’t many options you can get right now. But two leading flagships, Galaxy S10/S10+ and iPhone 11, Pro and Pro Max, have come loaded with next-gen wireless technology. Also, there are several devices from Intel, Broadcom, Qualcomm, Ruckus, etc. that have arrived to fuel WiFi 6 in smartphones and PCs.
