Make sure that Ideal rate manager properly selects MCS based on the configured channel width.
The scenario considers an access point and a fixed station. The access point first sends a 80 MHz PPDU to the station, for which Ideal rate manager should select VH-MCS 0 based on the distance (no interference generated in this test). Then, the access point sends a 20 MHz PPDU to the station, which corresponds to a SNR 6 dB higher than previously, hence VHT-MCS 2 should be selected. Finally, the access point sends a 40 MHz PPDU to the station, which means corresponds to a SNR 3 dB lower than previously, hence VHT-MCS 1 should be selected.
