The result was that APs were above and below each other on the same channel, resulting in excessive CCI The APs should have been deployed so that they were not directly above and below each other and so that they used varying channels between floors

The result was that clients could only connect to APs on their floor and, in a multi-floor deployment, you want clients to connect to APs on other floors in case they roam between floors.

The result was that AC) was increased because the APs were deployed above and below each other on the same channels.

The result was that the frequency utilization was too low for the clients to capture RF waves on which to transmit their signals.
