Took a trip to Turkey Creek and did get 4G!! Here are the speed tests:
The High:
The Average:
The Medium:
The Low:
As you can see, the speeds do range a bit.
The average stayed around 4-6 Mbps, followed by the lows which were 3.0-3.5 Mbps.
The high speeds stayed around 15-18 Mbps, followed by the mediums which stayed around 7-11 Mbps.
Also, the bars shown in the pictures might not be the bars at the time of taking the speed tests. I did have full bars and got around 2.3 mbps once, I didn't grab a picture at the time.
