We are seeing that many, if not most in some cases, students are using
wireless exclusively in the dorms for laptops/PCs- the wired network is
bocoming a place for Playstations, XBoxes, etc for many users. We have
students show up that have grown up wirelessly- try to give them an
Ethernet patch cable and they tell you that hey don't have a phone to
plug in, especially not one that needs that big of a cord...

Is certainly a culture change to be monitored as you bring wireless to
the dorms.

Depending on what system you choose, the dynamic radio management/pico
cell settings can certainly help tame a dense design. But also consider
whether you'll ever need location-based services- if so, it's a whole
different approach than just getting lots of wireless to a given area.

  Surely if your *floors* are only 10db, room penetration shouldn't 
be a problem, should it?

  I've stayed in hotels about this size that seemed to be adequately
covered by an AP every couple of floors, alternately offset toward the
ends....  Of course, usage volume is likely to be higher in a dorm,
but if wired ports are also available then perhaps not beyond
capacity.

  I haven't actually used them yet, but the places where I need 
density of coverage without reducing power, I'm looking at the Xirrus
wi-fi array product as a likely solution.
