I'm early in the WLAN learning curve. I can understand how more complex modulation schemes allow more data throughput. However I don't understand how going to wider channels allows more data throughput without changing the modulation.
Does more channel width allow for faster / more aggressive transitions between the modulation states?

More reading lead to an explanation.
The thing I was missing was that the QAM modulation is applied to each subcarrier. So doubling the channel width doubles the number of subcarriers, which doubles the data rate.
