Free registration required

Executive Summary

The 802.11 hardware has ultimately made its way into the electronic consumer market. But, especially in home networks, it clashes with high quality demands of rich multimedia streaming applications that WirelessLAN can only partly cope with. This paper describes basic features and fundamental flaws of 802.11, particularly with regard to multimedia streaming and Quality-of-Service (QoS) requirements. To overcome current problems of missing bandwidth resources in wireless home environments, the presented work points towards future multi-interface extensions of 802.11-based networks, in combination with decentralized Wireless Mesh Network (WMN) structures.
