https://www.plumewifi.com/ is making all sorts of promises, can't tell
what they are using.
A new one just cropped up - portal - where their kickstarter claims
they are using openwrt. Anyone know anything more about it? Not clear
what chipset they are using but since they are based in taiwan I'd
guess it's mediatek, but it could be qualcomm?
https://www.kickstarter.com/projects/portalwifi/portal-turbocharged-wifi?ref=email
http://getportal.io/ has more "details" and early backers should be
seeing routers soon.
They are all claiming massive improvements in wifi performance mostly
based on whatever 802.11ac based technology they are using, I keep
hoping at least some of the above were also paying attention to bql,
fq_codel, per station queuing, etc.
Dave-
Thanks for pointing those out (I'll volunteer that Ayrstone AyrMesh is
also, of course, based on OpenWRT and Open80211s, for those on U.S. and
Canadian farms. I don't claim that we're improving on anything but
getting moderate-bandwidth LAN connectivity over very large rural areas).
I love the idea of meshing WiFi systems adapting their channel settings
around local interference... so the Plume in my house detects that my
next door neighbor's Portal is interfering, so it changes its channel.
However, the Plume in my garage is much closer to the neighbor behind me
than the Plume in my house, and changes the channel to avoid them. This
then interferes with the neighbor's Portal, which changes its channel to
avoid my interference, which then interferes with the neighbor behind
me, who changes channel to avoid that interference...
And, of course, as you point out, this is a situation ripe for
bufferbloat (we know that mesh networks are potentially, ah,
troublesome). On the other hand, you, Jim, and others have been banging
the drum for 6 years or so, if memory serves. So there's no excuse for
new products coming out to NOT use bql, etc. If the word has gotten down
to the least capable wireless networking developers (i.e. me), everyone
should be up to speed by now.
So, on balance, I'm not too worried about these things increasing
congestion - in a typical apartment building I'm not sure they'll be
actually be working long enough to congest anything. ;-)
Humorously,
Bill
P.S. for the mathematically inclined, note the discrepancy between the 3
distinct channels in the 2.4 GHz. band and the application of the
4-color theorem to channel selection. Sucks...
