The antenna gain specs for the AIR-ANT-1B are 3.8 dBi (2.4GHz) and 5.8 dBi (5GHz). The AP provisioning page on the controller will only allow gain values in .5 dBi increments. There is also this tidbit taken from the AP-22x data sheet:
Does this mean the gain values for the AIR-ANT-1B should actually be 2.3 dBi (2.4GHz) and 2.8 dBi? And, if I must enter this in .5 dBi increments, should I round down or up?

I would do 3.5dBi and 5.5dBi (round down to the nearest 0.5dBi). If you are US, you don't need to account for the diplexer loss unless you just want to as you shouldn't be anywhere near the regulatory limits (so 2.0dBi and 2.5dBi provisioned acounting for the diplexer loss).
Hope that helps.

Needing to get these online I set them at 4.dBi and 6dBi, so I rounded up. Would that be ok or do you reeccommend rounding down? This is for a classroom building in a campus setting and some classrooms have fairly high density seating capacities.
