  Abstract

WLAN(Wireless local area network) is serviced in ISM(Industrial Scientific Medical) band where Bluetooth, Zigbee, and other WLAN signal coexist. They affect each other as interfering signals. Among these interference signals, WLAN service quality is mainly affected by overlapped basic service set (OBSS) WLAN signals operating on the same channel or the adjacent channels. In this paper, we define the throughput efficiency and interference robustness as performance specifications to quantitatively measure the service quality of WLAN according to the OBSS signal interference. We set up a test procedure for measuring WLAN service quality based on these specifications. In addition, we verify the effectiveness of the proposed method by applying it to the test for the commercial WLAN access points (APs) and analyzing the results. The measurement specification and test procedure proposed in this paper can be applied to product performance comparison and analysis in various aspects when evaluating the performance of APs.
