3gpp rel7 hsdpa/hsupa goes about 4 fold faster than that down and twice 
as fast up without having to resort to mimo.

whether any of these technologies can beat a recycled 802.11n phy with 
time division duplex in the mac layer as far as throughput goes is very 
much an open question.

most of what you'd consider really high throughput from lte systems 
comes a the expense of spectrum that is shared with a a lot of other 
devices so don't think for a second you're going to get 170Mb/s down and 
80Mb/s up.
