is there any documentation that shows the radiation patterns of these AP? At least the AP15 has a metal back so do the radiation lobes project forward or do they create a 360 sphere?

Thanks, so it appears based on that doc these are intended to be ceiling mounted and according to the side view, if I'm understanding this correctly there's only slight degredation to the RF radiation going in the direction behind the AP. I would have assumed more due to the metal back of the AP.
I believe the radiation patterns are logarithmic. So a 3 db drop is about half the range/power. Based on the picture it appears that there is about 10 dB less going out the top. So that would be less than 1/8th of the power being focused down.
