I think most of it has to do with the fact that certain antennas get removed form towers to make room for those 4g lte antennas. Add realigning of antennas and added capacity due to antennas that were removed and it can cause these undesirable situations. I noticed this when LTE was being installed a few years back in Colorado Springs, and I feel your pain. I hope when all gets said and done with LTE things will get better, but I'm not keeping my fingers crossed. If it wasn't for my grandfathered unlimited data I would be over at AT&T in a heartbeat, their network has been kicking butt and taking names recently.
