The ceiling is so tall in this environment I figured it would be better to mount on the collumns which divide this large warehouse into 5 north-south bays. After reviewing the AP matrix, with current end-of-life notices, it seems the AP 11x is the best choice. The only issue could be the 115 has a built-in downtilt Omni, so it might be a better option to go with an AP-114 with three AP-ANT-1B antennas to get a true omni.
The 114 is ok with 802.11af power, which saves on power injectors, but does require 6.3.1.0 code.
Thoughts?
