Performance measurements and evaluation of video streaming in HSDPA networks with 16QAM modulation

The high-speed downlink packet access (HSDPA) communication protocol improves downlink performance on mobile networks and is currently being deployed in networks around the world. In Norway, two operators started offering this service in 2007. This article discusses performance measurements done in Telenorpsilas HSDPA network in Oslo in the context of video streaming. In particular, we present the results of streaming experiments measuring characteristics such as packet loss, latency, jitter and bit-errors. Based on this data, we evaluate the HSDPA networkpsilas suitability for real-time video streaming, and discuss what can be done to improve the quality of video streaming under the observed network characteristics.
