Yeah, last time this came up I referenced the WHO's statement.  However, 
there's a guy with a blog about the evils of wifi radiation... so..

Very cool, Ryan, thanks for sharing!

We did our shift to in-room a number of years ago, so we didn’t have cool 
visualizations of aggregate user experience like what products like Voyance and 
NetInsight provide today.  I can’t remember all the exact details, but we had 
to mine our controllers for data and logs showing decreased incidences and 
presence of things like co-channel interference to show improvements from the 
redesign.  Much easier today to let the magic machine learning analysis engines 
do that work for us!  :)

Re: [WIRELESS-LAN] Performance improvements from hallway to in-room

[Dan Lauing]

We don't get complaints about APs in the rooms, but I have thought about
starting a rumor that the real danger is ad-hoc/wifi direct printers. After
all, they're blasting at 20dbm out of the box compared to my whisper-quiet
APs. Parents that care would either take those things back to Best Buy or
have their child connect it to *our* network like a responsible adult. :)

[Casey Feskens]

We did before/after student satisfaction surveys and found a 50%
favorability improvement (35-85% good or better) moving to an
every-other-room in-room architecture vs hallway AP's.

We did just have our first request for AP removal though. Thankfully, our
Housing staff is accommodating.

Thank you for the information, however. Any amount of proof to help solidify

Subject: [WIRELESS-LAN] Performance improvements from hallway to in-room

All:

We all know that moving from hallway deployments to in-room deployments pays 
dividends.  This summer we started doing some re-cabling work on smaller dorms 
to move from hallway to in-room.   We also went away from Aruba higher 
performance APs to the hospitality APs for these locations.  Even though the AP 
cost is significantly less, the cabling costs made this move a premium option.  
Nonetheless, thanks to data provided to us from Nyansa Voyance, we are able to 
clearly demonstrate to Housing that these funds were well spent.  After the 
changes, these dorms went from some of the worst performing locations on campus 
to some of the best.  When you look at the graphs below, the Y axis is 
percentage of users that are affected by poor wifi performance (I believe 
Nyansa measures this as clients that experience a 25% retransmit rate from the 
AP to client).  With Nyansa, it determines behavior on usage level.  So when 
you see the dashed line, it means that usage was below or above the threshold 
during that time frame.  I picked the usage level that would show the most 
complete picture, but going from low/medium/high all show the same improvement 
levels.

Sometimes I wonder if we're the only campus that doesn't get that type
of thing. We used to have a few "can you turn off this LED" before we
just turned all of them off by default.
