Throughput calculation in a HIPERLAN type 2 network considering power control and link adaptation
Markus Radimirsch, K. Jobmann · IEEE Transactions on Wireless Communications · 2005
This paper deals with the combination of transmit power control and link adaptation in wireless data networks. The tools for engineering wireless voice networks are not necessarily suited for data communications due to the smooth transition between good and bad states in data networks. This paper proposes a theoretical model to calculate the throughput in a wireless data network using HIPERLAN type 2 as an example system. It is based on the computation of the probability density function of the signal-to-interference ratio (SIR) at the receiver and the calculation of the expected throughput value based on known throughput curves versus SIR. The results from the theoretical model are presented and compared to the results from a simulation model. An important outcome is that maximum throughput in the network is not necessarily achieved at maximum transmit powers.
