Detailed Description

Make sure that the correct channel width and center frequency have been set for OFDM basic rate transmissions and BSS channel widths larger than 20 MHz.

The scenario considers a UDP transmission between a 40 MHz 802.11ac station and a 40 MHz 802.11ac access point. All transmission parameters are checked so as to ensure that only 2 {starting frequency, channelWidth, Number of subbands in SpectrumModel, modulation type} tuples are used.
