Convincing Management to Migrate to WiFi?

bergeron76 asks: "My company is currently preparing to relocate to a new location out in the suburbs. We recently received a very outrageous quote to move our computers, telephony gear, and ethernet wiring to our new office. I'm trying to convince management to switch our call-center to WiFi for a fraction of the "relocation" quote cost. The problem is that they are still considering outsourcing the ethernet wiring at an exorbitant rate! Can the Slashdot crowd help me come up with more selling points for WiFi (beyond the obvious) before I make my formal proposal?"

Apparantly my High School is adding wifi coverage next year becuase there are a lot of places in the school that haven't been wired up as the number of computers grows. Its reached the point where its impossible / majorly expensive to wire them so they are putting in a wifi network to cover them.

While I trust some security will be used. (perhaps foolish trust, these are the people that didn't close port 80 when nimda came and flooded the network) I'm pretty sure a non trivial number of people could own that network in a hurry. We are talking somewhat sensitive data too like grades and inter-teacher corespondence.

My question is what exactly can be done to ensure that wireless networks are secure? They will never be 100% but can they be made good enough for reasonably sensitive data?
