Wi-Fi networks are the first and sometimes only choice for the video streaming in homes, airports,
malls, public areas and museums. However, Wi-Fi networks are vulnerable to interference, noise and have
bandwidth limitations. Due to the intrinsic vulnerability of the communication channel, and the large number
of variables involved, simulation alone is not enough in the evaluation of the performance of wireless networks.
Actually, there is a tendency to give experimental tests a central role in the assessment of Wi-Fi networks
performance.
The paper presents an experimental analysis of the effects of cross traffic on the performance of video
streaming over Wi-Fi, based on cross-layer measurements. Experiments are carried out in a semi-anechoic
chamber, to prevent the results from being influenced by external factors. The experimental results permit to
analyze the influence of cross traffic characteristics on cross layer measures and objective video quality metrics
evaluated through a standardized approach.
