I was driving on the Hoan Bridge yesterday and had 4G! I know it's most likely just for Summerfest, but nonetheless, I was HAPPY! The 21.65mbps was at the peak of the Hoan. The 4G was between the Port of Milwaukee and the northern end of the Hoan. Sadly as I traveled further West (794 to 94 west), the signal died. I know one thing...this may actually make me want to go to Summerfest...just to play around on 4G...no matter how crowded the network will be. Haha.
