Just be ready for some amount of backlash from an angry/ignorant parent. Every 
year (including yesterday) we have parents contact us saying we needed to 
remove all APs from bedrooms because of the health risk to the students living 
in those spaces.

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

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.
