I am not sure that I have the patience to write a longer rebuttal to dedub, but I what I interpret he means is that non utilization is poor resource utilization.
The problem with this perspective, as I stated earlier, is that wireless networks are rarely, if ever subject to non utilization. Rather, dedub's issue is really with under utilization. But I have no issue with under utilization because it means that congestion is far less likely, hence capacity is apt to be there for those who actually need it when they need it.
To present an analogy, harping about under network utilization as poor resource utilization would be like stating that many highways are poor resource utilization because they are not constantly full of traffic.
And by the way, that guy who is using 600 GB of WiMAX per month is transferring on average 1.9 Mbps every second of every day. That is abuse.
