Modern wireless communication is based on ever-more-complex algorithms to exploit the characteristics of the radio channel in an ingenious way. Its performance is more and more frequently evaluated by the use of simulations -- a remarkable benchmark. Nevertheless, at the end of the day, it is not the simulated link capacity that counts but the throughput actually achieved by a system. HSDPA and WiMAX are based on MIMO, feedback, and different modulation standards -- three properties that make it especially challenging to measure the performance of their physical layers with reasonable effort. Nonetheless, it can be done. If cleverly used, a testbed can combine the strengths of Matlab simulation with the utilization of a real physical channel, in a time, cost, and manpower-efficient manner. Of course, such an approach does not come with real-time capability, but that is actually not needed to evaluate the average throughput, as the techniques and results presented in this talk show.
