Abstract(in English) | In this paper, we evaluate Quality of Service characteristics of MPEG-DASH using 4K video over various wireless networks. We also evaluate the effects of various environments, such as the number of users who share the same wireless channel or bandwidth and users' behaviors (e.g. still, walking, and moving on subway), over Long Term Evolution (LTE), 2.4 GHz and 5 GHz Wi-Fi networks. The results conclude that, in case of LTE and 5 GHz Wi-Fi networks, mobile users enjoy high quality 4K video without any video playback interruption in any situations, even on subway. However, in case of 2.4 GHz Wi-Fi networks, mobile users are forced to experience very low quality video with long video playback freeze. This is because network quality of 2.4GHz Wi-Fi network is quite low due to interference waves from other access points of which wireless channels are severely overlapped. |
