Study of the throughput of WLAN according to channeling and density of AP

This study is dedicated to investigate WLAN throughput based on 802.11 data communication standard which employs 2.4GHz band, depending on its AP channels and density. In a space with high density of WLANs, throughput can be decreased due to radio wave interferences. In light of this fact, an experiment scenario has been created consisting of multiple WLANs where throughput can be measured with different combination of channels, consequently making it possible to determine more effective combination of channels. In parallel, throughput has been recorded with varying the number of APs installed within the experiment site to Fig. out the relationship between the number of APs and the throughput. According to the result of the measurement, channel 1, 5, 9, and 13 are suggested as more effective combination of channels, and declining throughput is shown as AP density increases.
