Executive Summary

Integration and seamless networking of different wireless technologies is one of the driving scenarios in the contemporary research. In recent years, mobile phones have seen an influx of attractive on-demand multimedia services with strict QoS requirements. This paper investigates the QoS for delay sensitive services under the design framework of a heterogeneous network. Multi Radio Transmission Diversity (MRTD), which exploits the benefits of dynamic usage of different access technologies, is tested using simulations for Voice-over-IP on multi-radio wireless devices. The network technologies in this study include HSDPA on UMTS and IEEE 802.11.
