Thanks for the update to the running list totals, I think a small tweak is needed to the Northern WI LTE Sites Accepted %
"LTE Sites Accepted = 5861%"
Guessing 58.61%??
The 800LTE thread is in the premier sponsor section. From your iPhone dial *3001#12345#* dial, if you are connected to LTE you will see a menu item for "Serving Cell Info", under that is Freq Band Indicator, 25 is 1900LTE 26 is 800LTE
Rapids is a launched LTE area (http://newsroom.sprint.com/news-releases/sprint-turns-on-more-4g-lte-markets-expands-lte-coverage.htm). I've been in the area previously and had LTE, doesn't mean they can't be tweaking or something now. Looks like you are a sponsor, don't forget to check the sponsor maps for that area to see what accepted upgrades there.
I was on Hwy 10 from Point to Marshfield yesterday afternoon and was having connection problems as well. Once I hit the tower that has LTE on the south side of Marshfield I was fine again.
Press release from today says LTE for Marshfield/Wisconsin Rapids in coming months:
