If everything is within a good range of the AP, this would work pretty well. If you end up needing multiple APs, or you have many stations, I expect that you will be better off with more APs at lower power, each using different channels.<br>

hmm, I'm skeptical. To use multiple carriers simultaneously is difficult<br>
per RF issues. Even if that is somehow resolved, to increase throughput<br>
usually requires some form of channel bonding, i.e. needed on both sides,<br>
and brings in issues with preserving frame ordering. If this is just<br>
channel hopping, that needs coordination between both sides (and isn't<br>
simultaneous, possibly costing more than any potential gain.) An AP only<br>
solution can use channel switch announcements (CSA) but there is a cost to<br>
those as well.<br>
<br>
I guess don't see any break though here and the marketing on the site seems<br>
to indicate something beyond physics, at least the physics that I<br>
understand. Always willing to learn and be corrected if I'm<br>
misunderstanding things.<br>

"Portal is the first and only router specifically engineered to cut<br>
through and avoid congestion, delivering consistent, high-performance<br>
WiFi with greater coverage throughout your home.<br>
<br>
Its proprietary spectrum turbocharger technology provides access to<br>
300% more of the radio airwaves than any other router, improving<br>
performance by as much as 300x, and range and coverage by as much as<br>
2x in crowded settings, such as city homes and multi-unit apartments"<br>
<br>
It sounds like they are promising working DFS support.<br>

It's not clear what chipset they are using (they are claiming wave2) -<br>
but they are at least publicly claiming to be using openwrt. So I<br>
threw in enough to order one for september, just so I could comment on<br>
their kickstarter page. :)<br>
<br>
I'd have loved to have got in earlier (early shipments are this month<br>
apparently), but those were sold out.<br>
