This is not exactly true.
With the 3G networks (GSM) you can get.
7.2-Mbps HSDPA (downstream) 5.8-Mbps HSUPA (upstream)
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.
LTE speeds are much more comparable to Wimax.

For business purposes such as fixed wireless access for small branch offices, it would seem that Wi-Max is superior to current GSM and CDMA proprietary networks in that the upload/download speeds are symmetric. It appears that GSM and CDMA networks are based on the asymmetric low upload bandwidth/high download bandwidth model, thus placing severe restrictions on business use for fixed locations.
