In order to investigate the communication status of wireless LANs, several research have been proposed to estimate congestion conditions in wireless environment using wireless frame capture. However, as the wireless environment is updated to 802.11ac and 802.11ax, it is expected that wireless frame capture will become more difficult than before due to the multiple transmission of signals in the space by MIMO communication and beam-forming in these standards, as well as the increase in communication speed and bandwidth utilization. In this report, we describe the results of capturing wireless frames sent from an access point in a typical 802.11ax/802.11ac environment while changing the conditions of the wireless LAN settings.
