Making the best out of the architect demands.

Hello again r/Networking,

After much struggle on where to locate our outdoor MIST AP61 to cover a public square, the architect left us with the only option to put them under bench banks, around 20 cm up from ground level.

We expect low to medium density most of the time, and for special occasions where high density will be required, ad-hoc APs will be deployed.

My question is, how should I tilt the AP? Options are:

• Mount it vertically, which at first seems like the best option.
• Down tilt it, to avoid getting the beams directed to the bench bank, and hope the reflection on the floor will work our way.
• Up tilt it, to try to reach further. Probably the last favorable option, as on the opposite side there will be other AP pointing in the same direction.

Any thoughts or recommendations are of course very much appreciated!

Thanks in advance!
