Sprint's WIMAX does not get anywhere near 9mb. You are lucky to see over 2mb most of the time with Clear Wireless Network. LTE will be a much better network than WIMAX period and should perform better.
exactly
early tests of LTE have shown it getting anywhere from 7 to upwards of 30 Mbps
thats pretty amazing
