As video communication services are progressing, video-telephony services using mobile Internet access have become popular. However, in wireless LAN, the performance for quality of services is degraded when traffic extremely increase. By using the evaluation method ITU-T G.1070, this paper experimentally evaluates packet loss of video traffic and the objective quality when radio resources are not enough. Moreover, this paper discusses optimum value for video bit rate and frame rate to maximize video quality when wireless channel is extremely band-limited, considering trade-off packet loss rate and video bit rate. |
