While the 801.11 working group finishes off 802.11ax, regulators are getting the 6 GHz band ready for use. Efforts are underway to eventually free up 7 GHz over the next couple of years.

  • 2.4 GHz
  • 5 Ghz
  • 6 GHz

Some vendors have dual channel designs and are calling them tri-band. That is misleading as there are no additional bands but rather the vendor is bonding channel A and channel B to aggregate more throughput.

With three bands there will be more room for dense WiFi areas in high population density urban areas. New York city is so full of Wi-Fi hotspots it’s hard to find the right one initially. Once the WiFi is added to the phone/tablet/pc it will remember it.

The main move to 6 GHz is to reduce the overcrowding in the 5 GHz band. Some of the 5 GHz band is used for other purposes while the 6 GHz will be shared by WiFi and cellular interests.

The Intel AX200 and AX201 were designed and implemented before the standard was completed. Its likely Intel will have some fresh new designs to be released Q1 2020.
