The work in this paper presents physical layer throughput measurement results of a WiMAX link implemented according to IEEE 802.16-2004. The measurements were carried out in an alpine and an urban scenario using the Vienna MIMO Testbed. The paper compares the measured throughput to three different theoretical bounds: the channel capacity, the mutual information, and a so-called "Achievable throughput" which takes inherent system losses into account. Furthermore, the impact of different channel codes and channel estimators on the measured throughput is analyzed.
