Hi guys, What type of AP should I choose for such a mezzanine warehouse?

Height: 3 meter

I have 5520 Wireless Controller

Thank you @marce1000 , I watched these videos and posts. But I can't choose an AP model because traditional warehouse and mezzanine are different types. Unfortunately, these videos did not solve the problem.

 - As Leo says because of the mezzanine layout consider a wireless site survey as even being more mandatory ,

Get a WiFi site survey/planner done correctly.

No one can tell you what ap or antenna you should use. Like what the others have mentioned, to really know where the ap should be mounted and what ap or antenna to use, a site survey would be your best choice.  You will have folks here that might suggest just using Omni’s, other would say a patch straight down and other might say a mix or patches on the wall and Omni’s. 
the biggest issue is where can equipment be mounted, how often does the product change, how high can the product be stacked and if the racks and locations change over the years.  The latter will make you redesign every time the layout would change.
