A site survey is critical when planning a WLAN.
Oh, we had the site survey, and a great plan based on what we learned
during the survey. However, all of that was for naught when the
antennas on approximately 90% of the WAPs were installed with their
signal propegations focused perpendicular to the floor, resulting in a
radio environment that is much different from what you think you have.
With antennas above the ceiling, this is something that can take a few
days to notice.
I am not saying this is common, but this is the kind of thing that
causes just enough of an issue to annoy users who may already be hostile
to a change in their work flow. Wireless is subject to all kinds of
small quirks like this, so I would add to the previous suggestion that
you need a strong attention to detail, and lots of in depth testing
before full deployment. I would also suggest that you be very sure that
you have a fast, simple system for problem reporting during initial
deployment. The problems that seem small can develop into a serious
issue as you expand your deployment. Without thorough reporting you
don't stand much of a chance of working things out before things start
to snowball.
