If you're going to be really measuring yourself against an SLA, the only sane
way I can see would be to do so with a metrics tool like 7Signals, Streetwise,

A large cost of a wired connection is the actual switch port. When we reduced
the wired connections in our dorms a few years ago, we pulled out $1 million
worth of switches which have been redeployed elsewhere.

How do you plan on imaging those machines? I assume they are Windows?
I have not found a commercially supported solution for this.

I do not have the same confidence in wireless as I do wired. There is no
control over the airwaves like there is over physical cabling, and some
interference cannot be dealt with (like visitor's mobile hotspots).

The other piece to consider here is the life-cycle of an AP against the
life-cycle of a switched port. In most cases, an AP will be replaced at around
the 5 year mark, mostly to advance to newer technology, but also because of
more aggressive EOL on the vendor side.
Contrast this with a
Exactly. As much as we try, wireless cannot be promised or guaranteed the same

You're point is well taken, but the logic is a little flawed. You're

We tried putting classroom computers on wireless, but ran into problems with
waking computers. Our patch management procedures rely heavily on waking
computers during a maintenance period at night, and we couldn't find a way to

While wireless classrooms may experience growing pains at the present time, I
do not see how they won't progress as time marches on, as is the case with all

there will be a place for wired and a place for wireless.
