Help me with implementation wireless with cisco aironet for specific topology

[alexandru.cacean]

Hello.

We have a 5 storey building.

My question: Is a good idea to install one Aironet 3500 or 3600 series AP with multiple external antennas and to place each antena on every storey ?

Maximum number of wireless clients will be ~200.

You can see the described topology on attached image.
