This paper presents experimental measurements of Real Media audio/video streaming applications on an IEEE 802.11b wireless LAN. Empirical traffic measurements collected using a wireless network analyzer are used to characterize RealMedia streaming workloads. In addition, we study the relationship between the wireless channel error rate and the user-perceived quality of RealMedia streaming applications. We find that the RealMedia application provides relatively robust audio and video streaming quality in all but the poorest of wireless LAN conditions. Finally, competing TCP/IP Internet traffic is found to have relatively little impact on the quality of UDP-based Real Media streaming sessions.
