When they begin the install of NV gear they generally shut down the tower. When it comes back up your service will probably return to normal or slightly better. Also when it comes back up, it probably will not be broadcasting LTE. AlcaLu likes their markets to have a significant number of sites ready for LTE integration before they start that phase, so expect this to be months down the road. They will have almost all of the physical LTE work complete before they leave, but they can't integrate until new backhaul arrives. Watch for a telecom crew trenching for new fiber to the site.
