This would give access to an impressive number of additional Wi-Fi channels:
- In the US:
- 59x 20MHz channels
- 29x 40MHz channels
- 14x 80MHz channels
- 7x 160MHz channels
- In the EU:
- 24x 20MHz channels
- 12x 40MHz channels
- 6x 80MHz channels
- 3x 160MHz channels
As a Wi-Fi Engineer and seeing channel related problems every day, I get very excited knowing that more channels could become available. It could solve a lot of our issues and improve the overall performances of our Wi-Fi networks.
However, in Canada, the ISED does not have current plans of opening up the 6GHz band for licence-exempt use.
Current Use of the 6GHz Band in Canada
- 5925-6425 MHz: Two-way Backhaul. Uplink communication for FSS (Fixed Satellite Service) (delivery of broadband services + distribute TV programming)
- 6425-7125 MHz: two-way Backhaul + TV auxiliary services and studio transmitter links.
The Near Future (2018-2022)
Here is the spectrum outlook priorities set by ISED for the next 5 years (2018 to 2022). As you can see 6GHz has been assigned a priority of 3:
In parallel, the IEEE could potentially decide to only allow certain amendment to be used on the 6GHz bands which would strongly push ISED to release these frequencies for Wi-Fi use. It is already being said that the 802.11ax wave 2 devices will be able to operate on the 6GHz band.
- ISED Spectrum Outlook 2018 to 2022:
- Wi-Fi Trek Présentation from Chuck Lukaszewski « Opening the 6GHz band for unlicensed operations » :
- FCC Notice of Proposed Rulemaking « UnLicensed Use of the 6 GHz Band »
- EU Radio Spectrum Committee Working Document « Commission paper on a draft Mandate to CEPT on RLAN in the 6 GHz band (5925-6725 MHz) »
