In a multifloor office building that contains an auditorium in the basement, all the access points are joined to the same WLC. The plan is to implement a high-density, high-speed design in the…

A single VoWiFi RF profile applied to all APs would limit throughput and cell design in the auditorium, which requires a high-density configuration incompatible with VoWiFi tuning.

AP groups let administrators map specific RF profiles and WLANs to a defined set of APs under the same WLC. The auditorium group can carry a high-density RF profile with aggressive data-rate minimums and tight cell sizing, while the office group carries a VoWiFi-optimized RF profile with appropriate admission control and roaming parameters - all managed from one controller without additional hardware.

A single high-speed RF profile applied to all APs would compromise voice quality in the offices, where parameters like EDCA, admission control, and cell overlap must be tuned for VoWiFi.

Using separate controllers per area would technically work but adds unnecessary cost and complexity when AP groups already provide per-area RF profile isolation on a single WLC.
