Q: How to choose between hallway and in-room AP's?
A: The primary concern for hallway versus in-room mounting in a multi-tenant dwelling is effective attenuation of interfering signals from adjacent AP's. Even though they are on orthogonal channels, they are in-band and will add to the noise floor which will ultimately degrade performance.
At 2.4 GHz where there are only three orthogonal channels, on-channel interference is highly problematic if channels are reused without sufficient physical separation. Mounting AP's in-room will use attenuation from building materials to advantage as signals must pass through one or more walls/floors. This effectively reduces interference for both adjacent and co-channel signals. Mounting AP's in hallways is not a good practice and should be avoided.
