Beacon airtime overhead tool;
http://www.revolutionwifi.net/revolutionwifi/p/ssid-
overhead-calculator.html
The cases where it reaches 100% where not so far of urban areas today.
Hope it helps with airtime policies and the like.

How did scale go?

Is there any ath10k hardware that is especially recommended? The Scale network
is currently all WNDR3800, but we would like to get a handful of -ac routers to
see how much of our userbase is using -ac equipment

A few more things for the list:
- The number of stations that have packets queued at the AP over time.
- Distribution of traffic between protocols (v4/v6, TCP/UDP/others).

Airtime fairness is upstream in both mainline and LEDE for ath9k. There
have been some preliminary developments for ath10k (looks like we can
get the data we need), but nothing that works yet. Should be possible to
get it to work for mt76 as well, at least.
The fq_codel-based queueing stuff is active for both ath9k, ath10k and
mt76, though.

Hmm, things that might be interesting:
- Distribution of client capabilities (5/2.4Ghz, MIMO mode, n/ac,
achieved rates, etc. - however much data you can reasonably gather)
- Lasthop latency experienced by the clients (you could get this by
capturing TCP handshakes and measuring the ACK-SYNACK delay, as shown
in Figure 1 of this paper:
https://dl.acm.org/citation.cfm?doid=2999572.2999603) - this could
give an indication of bloat in the client drivers.
- QoS usage (how much traffic is sent on each of the VO/VI/BE/BK
queues).

I think we are getting to the point where ac is fairly common, at least
in phones. But data on this would be good of course :)

I'm getting ready to finalize the build for the Scale conference, is airtime
fairness upstream in LEDE for both ath9 and ath10?
Has it been ported to anything else?
Is there anything you would like me to gather in this environment?
I've got a lot of the wndr3700/3800 APs (ath9k) and would like to get a handful
of -ac devices to see if there are enough users who would take advantage of the
higher speeds to matter.
