Video Streaming over 802.11b in the Presence of Fading Due to Human Traffic and Bluetooth Interference

摘要

The performance of video streaming over 802.11b is evaluated through experimental measurements in the presence of fading caused by human traffic, distance and Bluetooth interference, which shares the same 2.4 GHz ISM band. A measurement network consisting of a desktop connected to the wired Internet at the University of New Brunswick (UNB), a wireless laptop and a Bluetooth smart phone were used for conducting all the measurements which were carried out at UNB within the D level of Head Hall. The received video signal quality was measured in terms of the clock jumps observed in the video showing a ticking analog clock. The results show a video capture range (VCR) for quality video streaming and a video lock range (VLR) where the video signal could not be acquired. The statistical results show significant negative effects of distance and human traffic on video streaming and received video quality.
