Overview:

With the emergence of high-speed wireless cellular networks, such as High Speed Downlink Packet Access (HSDPA) or WiMAX, new services with a high bandwidth demand have been introduced. One example is non-interactive video streaming. In contrast to wireline networks, the characteristics of wireless links, such as a time-varying bandwidth and the trade-off between delay and reliability, impose problems to a streamed video. This paper studies the impact of delay and losses within a Radio Access Network (RAN) on the video quality at the example of a state-of-the art HSDPA network. The nature of transmission errors is discussed.
