I would like to understand the relationship between channel bandwidth, frame utilization and CPEs, here some assumptions, please confirm if those are correct or wrong, I will appreciate if you add more info.
Does CPEs with higher modulation consumes less frame time? (Ignoring the fact that the AP will be able to talk with two AC compatible CPEs like Force 300-13L at the same time under certain conditions).
Does 40 Mhz deliver more data in less time that 20 Mhz? If that is true, Can I assume that increasing the APs channel bandwidth from 20 Mhz to 40 Mhz will reduce the frame utilization, meaning, it will support more CPEs connected? (Ignoring the packets per second load, which in my case is low, since the plans I offer are 10Mbps and 20Mbps and I have just few customers that use it a lot).
