WiFi 6 addresses the increasing number of devices in individual networks. WiFi 6 operates in the 2.4 GHz and 5 GHz bands and features improvements in throughput, multiple-device support, and WiFi spectrum efficiency. WiFi 6 and WiFi 6E are different. WiFi 6 is the latest WiFi standard that operates on the existing 2.4 GHz and 5 GHz wireless bands.
This WiFi standard is successor to IEEE 802.11ac (i.e. WiFi 5). WiFi 6 offers higher speed and greater coverage range compare to legacy wifi networks wifi-5, wifi-4, wifi-3 etc. WiFi-6 operates at 2.4 GHz and 5 GHz frequency bands. OFDMA concept has been introduced in both uplink and downlink directions in wifi-6.
DFS is a spectrum-sharing mechanism that allows wireless LANs (WLANs) to coexist with radar systems. It automatically selects a frequency that does not interfere with certain radar systems while operating in the 5 GHz band. An office WiFi design plan should utilize the 5 GHz channels properly. For example, if there are 6 total APs for office
The Wi-Fi 6E standard adds support for 6GHz spectrum, plus faster wireless speeds and lower latencies. But you'll need a new router and Wi-Fi 6E-compatible devices to tap into those new airwaves.
