I honestly haven't seen a faster speed ever. (Even from other people.) On my GS2, I maxed at about 2.2mbps. The GS3 shows much stronger signal (probably PRL related, aswel.)
But the stars are the towers in my area and the circle is my house.
The Sprint tower to the southeast of my house is the one that's getting LTE first. I'm really hoping I'm inside range.
EDIT: reason behind me making this thread is because if I go down the street (literally, about a football field), my speeds are .5 mbps. LOL I'm fortunate that my house is really good, I was just curious if the towers would be adjusted in any way that may hinder my house performance.
