This probably isn't a T-Mobile-specific question, but it was their map I was looking at and their service I'm considering switching to, so I thought I'd ask here.
Anyway, I'm wondering why these coverage maps always have random splotches of color for "excellent" or "strong" or "good" (etc.) signals all over the place. If a carrier has towers in a certain area, then shouldn't the entire area be covered, making the map have much larger and more consistent blocks of coverage? What causes a few blocks of an area to have "excellent" coverage, and then around it is "strong," and then it becomes "excellent" again? Why isn't it all the same in that area?
Thanks.
