For a visual representation of the channels&#x2F;frequencies, see perhaps:<p>* <a href="https:&#x2F;&#x2F;www.wi-fi.org&#x2F;beacon&#x2F;chuck-lukaszewski&#x2F;wi-fi-6e-the-details-you-need-to-know" rel="nofollow">https:&#x2F;&#x2F;www.wi-fi.org&#x2F;beacon&#x2F;chuck-lukaszewski&#x2F;wi-fi-6e-the-...</a><p>* <a href="https:&#x2F;&#x2F;www.juniper.net&#x2F;us&#x2F;en&#x2F;research-topics&#x2F;what-is-wi-fi-6e.html" rel="nofollow">https:&#x2F;&#x2F;www.juniper.net&#x2F;us&#x2F;en&#x2F;research-topics&#x2F;what-is-wi-fi-...</a><p>* <a href="https:&#x2F;&#x2F;www.ekahau.com&#x2F;blog&#x2F;channel-planning-best-practices-for-better-wi-fi&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.ekahau.com&#x2F;blog&#x2F;channel-planning-best-practices-...</a><p>5925-6425 MHz is UNII 5, and is the most available globally. 6425-7125 MHz is UNII 6, 7, and 8:<p>* <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Unlicensed_National_Information_Infrastructure" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Unlicensed_National_Informatio...</a>

It&#x27;s always amazing to me how reluctant everyone is to grant ISM bandwidth. If you watch a spectrum analyzer you&#x27;ll immediately notice that the ISM bands are packed and licensed space is <i>entirely</i> empty. At this point with devices being both much more dynamic and much more spatially multiplexed (and more directional) I have a hard time accepting arguments that really anything from DC to daylight should be licensed at this point outside of a few very small niches (GPS and airband mostly). We should be gradually deprecating equipment that requires absolute band exclusion to operate because just slicing up spectrum is by far the least efficient way of utilizing a finite resource.<p>It&#x27;s also worth pointing out that we&#x27;re about to <i>lose</i> about half of one of our ISM bands (915MHz, LoRa, Meshtastic, ELRS, various smart home protocols etc) due to the lovely folks at NextNav wanting dedicated bandwidth for a paywalled GPS alternative. It&#x27;s by far the best ISM band in the US for long range unlicensed communications due to being in a sweet spot of path loss, penetration, and bandwidth.

Going through their “economic advantage of 6GHz WiFi” document. It looks like there is a “fight” with telecom guys trying to license 6GHz for 5G and others fighting for it to be unlicensed.<p>Interesting to see that countries are tilting towards unlicensing even with strong lobbying of telecoms

FYI:<p>Wifi-7 modems (some of them are AP-capable) are now available for around 15-30€. They support all bands (2, 5, 6)<p>Have a look at the Mediatek (MT7925E) and Intel (BE200-BE202) cards. There also the more pricy Qualcomm QCNCM865.<p>The Mediatek and Qualcomm also works with AMD mainboards. The Intel cards are <i>not</i> compatible with AMD mainboards as they are using a proprietary stuff.<p>At leas the Mediatek works fine with Linux (currently running in Thumbleweed) and AMD.

I’ve been on a project for 2+ years to support automatic frequency selection for this. I’m excited to start seeing so much chatter about it.

I&#x27;m turning into a luddite - why do we really need this? Just slightly faster transfers?
