Wireless multimedia home servers are the next generation of home entertainment systems. From a single broadband connection entering a residence, the multimedia stream is transmitted to television headsets and other peripherals by using only wireless links. The provision of high quality time-critical multimedia services in indoor environment is very challenging due to high attenuation and multi-path fading caused by the walls and contention in the shared channel. In this thesis, we demonstrate that the newly proposed wireless standard on wireless mesh networks can help improve the coverage while supporting Quality of Service requirements of both multimedia and data users, when the video packets are given EDCA priorities based on their importance according to the new high definition video streaming standard H.264. We support our hypothesis by presenting test results gathered from both simulations and from a real implementation test bed, where we observe very low delay and very few packet losses in video stream and almost no loss in perceived video quality even in the presence of high contending neighboring data traffic
