So your saying the Radio Interface Layer and the rest of the Operating system which stands in between the software and the hardware has nothing to do speeds? That would be hard to believe. There is plenty between the radio firmware and the software used to do the testing that can hurt speed.
Not that it normally presents any large issues but it would be foolish to believe it cant.
