I'm not sure if these two sets of numbers line up. by a duty cycle do you mean transmitting a burst every x ms, or x amount of energy or ? My assumption has been that to get 30Mbps up, you were using all channels available. There are distinct steps in uplink bandwidth that I see in my data. I am going to try to get the resolution below a ms after the ethernet thingi arrives. This assumption incidentally finally gives me a means with outboard hardware to better apply a bufferbloat fix, being able to quickly sense how many channels are in use could [1] feed forward into buffer sizing in the router itself... Are you using some sort of gnu radio for your work? There's a pretty neat project doing 5g outboard too..
