I suppose it's possible that there are no other environments as
congested as the IETF...but the 802.11x vendors need to hope that
A couple of general questions about 802.11 at IETF in Japan
1) is there some aspect of the telecommunications/regulations here
in Japan restricting the number of channels for RF use which affected
the problem? Did it help or hinder? -This is a 'cannot fix' problem

Japan can use all 14 WiFi channels (World/ETSI can use 13, US/FCC 11).
The IETF network was restricted to the US 11 channels, obviously so that users
of US cards would not be left cold.
On Monday, and for some time on Wednesday, there were problems with overlapping
channels. In WiFi, channel
A couple of general questions about 802.11 at IETF in Japan
I think problems are not specific in Japan but may be specific in IETF.
There are only 3 non-overlapping channel (e.g. 1-6-11) in 802.11b.
Actually there is another channel (14) which almost non-overlapping
to channel 11. We enabled
On Monday, and for some time on Wednesday, there were problems with overlapping

Sometimes we intentionally use overlapping channel configuration.
Basically, overlapping channel reduced performance, but the connectivity
should still remain. But the number of connected stations per
you need to do some engineering in order to make is such that the ap's
sitting on the same channels can't hear to much of each other. noise is
the biggest killer here because it results in more retransmissions which
results in deeper buffers on the ap's which results in more
retramismission
actually japan has four non-overlapping channels 802.11 channel 1 6 11 14
whereas the US has only three because their 2.4ghz ism band goes from
2.4-2.5 and ours goes from 2.4-2.483. some commonwealth countries have
more stringent output regulations than the US or JP but that's not an
the accompaning issues is more than 60-100 clients per ap (and ~200=death)
really results in reduced performance as well, particulallry if most of
them are active so more ap's can result in better localized performance,
assuming you get a handle on the rf issue.
maybe at IETF55,
