Abstract

There is a growing demand for bandwidth as well as mobility. Within ETSI BRAN a wireless LAN called HIPERLAN/2 has been standardized. While data rates can be as high as 54 Mbit/s for a high carrier to interferer ratio (C/I), more robust combinations of modulation and code-rate have to be used and also retransmissions do occur when interference is present. This leads to much smaller effective data rates. Interference and link adaptation are therefore important topics. In order to have a realistic co-channel interference, two radio cells are implemented which interact with each other. In both radio cells detailed implementations of the protocols are used. Data transmission between the terminals is carried out via TCP/IP, respectively UDP. In this paper it is shown how throughput as well as delay can be improved in all load conditions by reducing co-channel interference and reducing the variations in the interference situation which significantly increases the effectiveness of link adaptation.
