...in ideal conditions, with no one else on the tower. Gee, thanks for setting unrealistic expectations (I've hit 35.6M down, 13.5M up with absolutely no one else on a sector, at maximum modulation in both directions).
Realistic speeds for the time being, when you're within a few miles of an LTE tower (not 3G, not WiMAX) are around 15M down, 5M up. Upload speeds will be lower than on AT&T or Verizon, generally speaking, because upload channels generally aren't congested and you have twice the bandwidth there to start with...well, AT&T doesn't in Chicago but 700MHz also travels farther so you can actually modulate at 16QAM wherever.
