| Abstract(in English) | Channel bonding technology, which bundles multiple adjacent channels, is one of the promising way for improving throughput performance in IEEE 802.11ac wireless LANs. However, the device using channel bonding would be highly likely to be exposed to severe competition with other devices. In our prior work, we clarified that there are three types of communication procedures of IEEE 802.11ac AP employing channel bonding due to different implementation among vendors, such as extended RTS/CTS (optional function). Then we clarified the communication performance employing static channel bonding with RTS/CTS in the case where multiple communication with different procedures coexist within channel width. We have observed that an AP using CTS-to-self actually exist, but its communication performance is still unclear in case where the CTS-to-self AP employing channel bonding is competed with another AP without channel bonding in the proximity. Therefore, in this paper, we investigate its behavior in terms of channel bonding to clarify its type, and thus we demonstrated that the AP that we used in our experiments implements dynamic channel bonding, and the impact of competition between AP with channel bonding and that without channel bonding can be alleviated only when they work on the same channel, i.e., primary channel of the AP employing channel bonding. |
