If people are curious what Cisco does for their 3x a year Cisco Live events (last week in San Diego there was 35TB of data transferred over that network), there's a panel discussion about how they deploy things and what tools they use for it.My understanding is that the most recent NANOG had issues with clients picking channels sequentially vs by signal strength. There may have been other issues but when all devices use 149 because that's the first they can and they get link that's not good. If people know of tricks to solve this when there are 600-1000 devices per room i am certain the NANOG eng team would love to know about it.not really; they're in denial. why did san antonio work; the only nanog in 4 or more which did? why does ietf work? wireless is ugly. few know how to deploy at scale. it's just not easy. randy
https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=76483&backBtn=trueThat's the session from Milan 2014, may require a free account to view the slides and video. The session from San Diego is at https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=83806&backBtn=true Doesn't look like they've finalized the slides and video for that session yet though.
In Milan they deployed 325 APs across 6 controllers (3 HA pairs). From experience at the US Live events, there's 10-15K people in the main hall during keynotes, there's probably close to 100 APs in that room alone with the stadium antennas for the density needed. There's a LOT of people trying to tweet during and this year periscope the keynote speeches.
If people are interested, I know a couple of the Cisco folks tend to lurk on this and other lists and can probably provide more details if asked nicely.
