Joel,
Heads up. Many vendors provide box mounted APs with only one radio at 2.4 GHz (e.g. your Ruckus reference) or selectable spectrum (the extreme network reference or even the Aruba AP 93H). Providing only 2.4 GHz is a solution that might not last for long and only providing 5 GHz could create problems with your community. We looked at those and decided that this type of investment wouldn't last very long. If a vendor had a 2 radios AP in a wall box format, it would be a completely different story (but can 802.3af support 2 radios and a switch?)

Something along the lines of one of these: http://www.ruckuswireless.com/products/zoneflex-indoor/7025 http://www.extremenetworks.com/products/altitude-4511.aspx http://www.panoptictechnology.com/smart-room-network-jacks/ They're designed to fit into a traditional electrical wall box (like the one that's probably already there for an existing network drop) and they provide a passthrough port, so a student can still plug in a wired device like an xbox without messing the functional parts of the AP. The student may not even know there's an access point there. This won't work for everyone, since the big Aruba/Cisco players don't have this form factor. We're small enough we don't even have a controller and use fat APs. But I thought this was still worth mentioning for those with mixed environments or anyone using Ruckus or Extreme.. As a side note: is anyone else eager for a common AP/Controller interaction standard, to be able to bring one vendor's access points to another's controller?

Typically amounts to setting a new min power level that the APs are not allowed to go below, and occasionally going old-school setting fixed power. I find the auto power/channel thing to be good, but not above reproach. -----Original Message----- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU>] On Behalf Of phanset Sent: Wednesday, December 19, 2012 11:10 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU<mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU> Subject: Re: [WIRELESS-LAN] Wireless in Residence Halls David, Let me add that we cover between 5 to 6 students per AP (we stagger APs between floors), and when an AP goes down, we rarely receive a complaint since there is enough overlap between APs. So we can take some time to fix the problem (referring to the room access issue). As Larry mentioned, we used to have many complaints with our hallway 2.4 GHz design, we have almost none with our bedroom 5 GHz design. The cost is different of course! BTW, good luck to have a decent coverage at 5 GHz if you plan to cover from the hallway. The attenuation is atrocious! It is hard to reach the room, and APs "see" each other in the hallway forcing the RADIO algorithm to reduce power.
