Hi,
I've been following the development of the MakeWifiFast project. I've
been using a router with an ath9k with fq_codel support and the airtime
fairness scheduler, and it has been working great.
I am interested in a 5ghz point-to-point link that could handle multiple
VNC sessions. This is just to bridge a gap between two buildings. The
clients would be using access points that have both the ath9k fq_codel
support and the airtime fairness scheduler.
I was wondering if anyone had any ideas. I would really like the
point-to-point link to have fq_codel support. There would only be two
peers, so I am not concerned about airtime fairness.
Thank you,
Noah Causin

Point to point on the ath9k with the existing chaos calmer fq_codel
code works ok. What I did for that ages ago was to limit the amount of
buffering to 12-20 packets in the driver using the (now obsolete in
the code landing) various qlen_* files, and also disable wmm. At
50Mbits,
I typically see 20-60ms latency on my p2p links which is probably
close to "good enough" for vnc.
But the header of your message had "AC" in it... and at this point, I
think going AC is good, regardless of the state of the drivers - you
should be able to get 260mbits or more, fairly easily out of that, and
so long as you can't saturate it, get pretty low latency, and we do
have fq_codel (if not airtime fairness) patches for the ath10k. The
DSPs are better.
Take a look at the latest ubnt gear. I'm using the indoor uap-lite's a
lot and I like 'em. They take to an openwrt reflash really fast. I
have not as yet found a suitable replacement for the nanostation M5,
but....

Thank you for your advice.
I am considering the Ubiquiti PBE-5AC-500 PowerBeam 5ghz AC Units.
If I run into issues with bufferbloat, I can bridge two ethernet ports
on a router and apply Cake shaping passively.
Also:
I didn't understand what you meant by "The DSPs are better."

The Digital Signal Processors in the 11ac radios are better than the ones
in the 11n radios.

In nearly any given environment, 802.11ac achieves one better mcs rate.

Fully-functional transmit beam-forming increasing the SNR at receive?
