The best conference WiFi experience I had ever with was the SIGCOMM'07
conference room in Kyoto International Conference Center
<http://www.icckyoto.or.jp/> in Kyoto, Japan. It showed nearly no
service interruption for my laptop. It might be interesting to learn
from our Japanese colleagues how they managed to make it happen.

I'm curious what the largest *successful* deployment has been (measured in
number of participants in a single room/hall/stadium/...) that anybody has
seen, within the IETF or beyond. The NYC article hints at the fact that the
limit may be hotel fiber, rather than wireless, in some cases. We seem to have
more experience with dimensioning those than other organizations.

Dave,
I think you will find that our NOC people have a great deal of
experience and perhaps even a list of do's and don'ts for this type of
design. In the end, this technology will not scale without bonds if
we're talking about n-thousand people sitting in a plenary hall, but
there are obviously a lot that can be done with a distribution of
multiple lower-powered (configured as such) units that don't use
overlapping channels, use of various 802.11 flavors (a, n, etc) and
more SSIDs, all in the name of load sharing.
While there may not be a document, and I agree that it would be useful
to have one, there is certainly a collective body of knowledge on this
topic (including a "never again use base stations from xxxx..").

The problem is that Wi-Fi was never intended for large halls and
thousands of people, many of them bristling with an arsenal of
laptops,
I don't recall seeing a document on this and the IETF track record has been
quite good.
We should share the joy.
