Like Leo mentioned, if it's an open area you know the approximate coverage. When you ask it's like a hospital wing or school wing, you can really determine that unless you actually place an ap in Like the corner room and see how far the signal covers. Also when you ask for a range, you need to determine what's your outer cell coverage going to be. For example, you might want coverage with a minimum of -75dBM and an SNR of -20dBm or it might be -65dBm and an SNR or -25dBm. All these requirements and the building construction determines how far an AP can cover. Building construction from new to old to very old buildings makes as big difference too. Your best way to determine that is to get an 3500i and put the 1260 IOS image an test for yourself. You might have to test various areas that differ to actually determine the coverage of an ap in an area.
