I've had the discussion with "radio guys" before regarding "fairness" of 
radio resources. They kept talking about "optimising the cell for 
throughput". I told them "then we should give the speaker with the highest 
bitrate and demand for bits as much radio resources as possible, and 
starve everybody else". This is of course not good for general customer 
satisfaction.

After a lot of discussions back and forth, we came to the same conclusion 
as you seem to have come to (if I understood Tokes talk correctly), in 
that "radio time" is the most fair resource. If someone has bad radio 
conditions then they get lower total throughput than the one with good 
radio conditions, so the fairness is "equal air time". This means 
everybody get equal part of the shared resource, and gives people an 
incentive to try to improve radio reception if they have trouble, and 
doesn't starve everybody else of airtime just because one device is having 
a bad radio day.

So full support for this approach from me, good job!
