The speed test shown is inside a building. For the last few weeks, LTE would only work for a few hours out of the day, and now it seems to work all day on this particular site. Hopefully a full blown launch in KC is around the corner. I hope anyway.
Here are screenshots of a live LTE site in the KC metro area (Lees Summit, MO). I have been able to use 4G LTE here for about 3 weeks. Thought I would share for anyone interested.
