Jon,
Given that the clients make all the decisions, how can we
assure, given 14 channels, that the users will equally balance
themselves across all 14, rather than bunching up?

ay to change it? thanks in advance.
We have 802.11a and b/g available with same SSID, and find Leopards only
connecting to b/g, not a.

yments - the best
example here is the ITU (International Telecommunications Union) which
sits almost 2000 users in one room. We user 4 Arrays with 15 radios
each for a total of 1.2Gbs of TCP Wi-Fi capacity.
Hope this helps...

I have both of these tools - the WiSpy device and software are good for seeing
the RF conditions (layer 1) but don't show things at higher OSI layers as
Airmagnet does. Also it's only good for 2.4Ghz for now, but they have a 5Ghz
on the roadmap.

The most used indoor bands will likely be the two lower bands
(5.150-5.250 and 5.250-5.350 which have power in the 40mW and 200mW
levels respectively), the two upper bands will likely be used more
frequently outdoors (due to their higher upper power level limits of
1000mW and 800mW).

We supplied wi-fi to Interop this year where 60% of all clients connecting were

Extricom uses a similar architecture to Meru to "schedule" packet
delivery from a central controller through APs.
The idea isn't new, since a similar method is used in the 802.11 spec to
protect "b" only clients from "g" traffic. The use of the term
"scheduling" is really not accurate since wha
What tool are you using for power?
This is important since you could be seeing data from probe requests
ACKs coming from the AP (as in a site planner tool like airopeek,
Airmagnet, etc) or raw RF data as seen in a Spectrum Analyzer
(oscilloscope, Wi-Spy, or the ones built into all our arrays).
Increasing the beacon rate is a tempting solution but is typically not a good
idea due to the "cost" in term of spectrum use for this management protocol.
