Testbedding MIMO HSDPA and WiMAX

Modern wireless communication systems employ MIMO and feedback-two properties that make it especially difficult to measure the performance of such systems with reasonable effort in actual outdoor scenarios. In this paper, we will present a time, cost, and manpower efficient measurement approach to evaluate the throughput achieved by such systems. Summer/winter, large distance outdoor-toindoor/outdoor, urban/alpine measurements have been carried out to successfully test this approach. Exemplarily, we report on the throughput gains (over TX power and base-station-antennarotation) of standard compliant 2 × 2 MIMO HSDPA and IEEE 802.16-2004 WiMAX when for example employing improved channel coding methods.
