>And you think the same problem wouldn't exist with 6ghz?
Yes. Probably because they have some basic grasp of electromagnetic reality, which perhaps you might consider studying a bit before forming strong opinions?
>It will be as crowded as 5
Physically impossible. 6 GHz simply does not have the material penetration, that's the point. Having way more raw bandwidth on tap, all available all the time without DFS plopped in the middle too, is also extremely helpful of course too. But the signal just not traveling as far and not going through walls well is the core thing. You don't need special effort EM shielding for it so much, bulk material will do it. And WAPs are cheap now. Having a higher number of smaller cells has been best practice for awhile already, and 6 GHz takes that much further.
We said this about 5Ghz when that came out. I'm sorry to say it's not true, there's more than enough spectrum in 5Ghz if properly managed and co-ordinated. I would rather fix that first. Why is it we can run WiFi for thousands of developers in one room/venue just fine but people living in apartment blocks are apparently struggling with a dozen devices per 60sqm apartment?
APs using 160MHZ channel widths with 1 or 2 spatial streams because it's cheaper than 80MHZ channels and 3 or 4 spatial streams. Absolutely crap 'auto' channel selection, too high a power (because cheaper than a second AP), poor AP placement and inappropriate channel width (in an apartment block 40Mhz per AP might be optimal).
To the extent "we" said this, we were absolutely, 100% correct. 5 GHz was and remains a massive improvement over 2.4 GHz, exactly as hoped. But in the decade and half since demands have gone up a lot. 6 GHz will be even better as it propagates even worse and has even more bandwidth available, while human population density won't change.
>I'm sorry to say it's not true, there's more than enough spectrum in 5Ghz if properly managed and co-ordinated
I'm sorry to say you're wrong, there is not remotely enough usable spectrum, and that's regardless of "proper management" which in reality is completely contrary to the practical reality local networks in a setting with a high density of independent people/organizations.
>I would rather fix that first.
That's nice. Most fortunately you are not in charge.
>Why is it we can run WiFi for thousands of developers in one room/venue just fine
That's a low demand situation under the control of a single entity where people are going to be understanding of compromise given the special circumstances, unlike in home or business.
>but people living in apartment blocks are apparently struggling with a dozen devices per 60sqm apartment?
You're wondering why might want their own independent LANs in their own homes? Well, I'm sure you can think of one or two reasons if you put your mind to it.
Most of 5Ghz is unusable because of DFS. In Australia, only 2 out of the 6 80mhz channels are usable. 6 Ghz has 6 of them completely usable today, with possibly more on the upper end usable in the future.
> 6 GHz simply does not have the material penetration, that's the point.
Really? Is there something special about 6 GHz absorption through common construction materials? Otherwise, why would a 20% higher frequency be that much worse?
Yes. Probably because they have some basic grasp of electromagnetic reality, which perhaps you might consider studying a bit before forming strong opinions?
