David,
I'm sure you can find a way to improvise with the wall mount bracket for the AP-303H and mount it on the ceiling instead, but I would strongly recommend against this. The antenna pattern is designed and optimized for the case where the AP is mounted vertically, at moderate height. More critically, the Ap-303H needs to be oriented that way, and using one of the Aruba mounts designed for the product to ensure sufficient airflow along the back of the AP to avoid over heating (and not trigger the thermal shutdown function).
A potentially somewhat better option would be to mount the AP higher up the wall, possibly flipping them upside down (antenna pattern has a moderate uptilt when deployed as intended; it may be better to make that a moderate downtilt when the AP is high up the wall).
Or just use APs that are intended to be on the ceiling, like the AP-303 or AP-505. I'm guessing you do not need the wired ports?

Subject: 303H Ceiling Mount
I know that the 303H APs are made for being mounted on the wall. However, has anyone used them on a ceiling? I know it is not optimal, but I am trying to get new networking equipment through E-Rate. Right now, all the 303H APs are located at outlet height in the classrooms. So teachers cover them with book cases, shelves (some metal), they get knocked off, etc. This was all set up before I started at the school.
My thought is to get new wiring run and get the existing 303H APs mounted on the ceiling for the time being. At least they will not get covered up and looking at the pattern plots that it cannot be any worse. Then my wiring would be ready for upgrading to ceiling mounted 300 or 500 series.
