Wow! As soon as I finished my reply I noticed 4G LTE on my phone! I went outside to test it (I can't in my office because my windows, which were recently replaced to conserve energy, do not allow a very good signal to get through). I ran speed test and got 23Mbps down load and 21Mbps upload. While the 23Mbps is a nice improvement I was surprised that the upload speed was so high. About a factor of 5 to 10 over usual performance.
