In this paper, channel capacity degradation is analyzed by computer simulation in the multi- cell WLAN environment interfered by adjacent APs. We build the WLAN environment with multiple APs interfering each other in various overlapping areas. At each cells, we increase the number of VoIP terminals and calculate the VoIP call quality based on the MOS. The capacity degradation of VoWLAN revealed in multi-cell interference environment, but it"s sufficient to serve in residential area.
