Seems like the LTE gets turned on and initially ping times are really high. Then they fine tune and it gets much better. I watched this happen (still need fine tuning for the west end towers) in Greeley. The process went just as described over and over, put up antennas, wait for backhaul (fiber installs seemed to be terribly slow which Sprint cannot control), wait for Century Link to connect the fiber to their network as they micromanage every bit of in ground communication here, turn on the Sprint equipment, fine tune, increase speeds again, then winning.
I agree with the improvements and am much happier than I was before. Some issues, but progress by the end of summer in all of Northern Colorado. Glad I stuck around!
Thanks to this group, its leadership, and members for seeing me through the dark times!
