I get 1500 at my house consistantly bit that's because there's a tower literally up the hill from where I live on the open space, the only spot I get horrible coverage is at the gym where it can be as bad as 20 kbs. It sucks
Although distance does affect speed, that is not the most prevalent factor. Here, I can have full bars on many, many towers and STILL get 20 kbs because the towers are severely overloaded.
