Abstract (in Japanese) (See Japanese page) 
(in English) In this article we experimentally evaluate MOS performance of VoIP
application transmitted by IEEE 802.11 wireless LAN system under congested
condition with UDP traffic. We examine the performance with automatic
control mode and with several fixed transmission data rates. Based on the
results we evaluate an automatic rate control method by setting a lower limit
of transmission data rate to avoid deterioration of MOS due to low rate
selection. The experimental results show that this method can suppress the
packet delay caused by random backoff and rate fallback functions, and
improve QoE of the application. Finally we also discuss how to determine the
lower limit of the data rate for the method.
