Given that, I believe that when comparing things that are already out there (first generation of WiMAX and HSPA), WiMAX has a very clear advantage! Second, Alamouti refers to the data rates but he also stresses the importance of the average cell throughput by explicitly stating that the achievable rates are a fraction of the peak data rates. I wish everyone else was as honest! Finally, since the data rate requirements on the internet are roughly doubling every two years, the industry has to keep up by deploying more antennas and larger bandwidths. Although I agree with you that 20 MHz and 4x4 antenna configurations are challenging, they may happen earlier than you think!

This may be true if a user is using alone in the cell 4*4 MIMO @ 20MHz, which will hardly never be the case. Roll out of 5MHz carriers is often a problem in many countries, when you expand it to 20MHw I let people imagine... 4*4 MIMO will never be usefull for handheld devices. When you compare what is comparable, HSPA is not that below WiMax claims in term of capacity. Plus it already works. Intel propaganda…
