Do you have any coverage plots? When I started the other thread, I was really looking for the technical merit's, more then the cost benefits or political arguments. I'm interested 802.16d vs 802.16e, some say 16e is the greatest, some say 16d is the best, what are the technical reasons behind which is which. My task at hand is to write up a comparison for the benefit of my boss, so that we can make an informed decision on which technology to choose.
I've read the specs, but I was hoping to get beyond that, and be able to include issues with real world deployments, pros/cons of either tech. We don't want to make the investments (we will run fiber to each tower) and replace our existing deployments with it. We do want to do voice as well (we have a switch and are a CLEC).
