Abstract :
In a wireless LAN quality of service (QoS) is limited by hidden nodes, coverage and delay spread. The channel access mechanism of HIPERLAN Type 1 will provide a minimum collision rate in addition to a fair sharing of resources among all nodes. The author investigated the influence of the packet length, number of nodes and lifetime on the expected user data rate. The results show that a HIPERLAN Type 1 system is very robust under heavy load conditions. Earliest data first (EDF)-scheduling of data packets enables tuning of multimedia performance by adding an optional buffer to the HIPERLAN user data interface
