a study on the impact of various modulation and coding schemes on wireless (wifi-6) performance

The performance of wireless networks depends on measuring the radio characteristics between the access point (ap) and client station (sta) within the same base service set (bss). in areas with high demand for wireless services, multiple wireless networks may overlap, causing interference and negatively impacting the performance of individual users and networks. this interference makes wireless radio channels more susceptible to interference from surrounding energy, directly affecting wireless networks' throughput. a new spatial reuse ieee802.11ax standard has provided the solution to address this issue. this standard performs a clear channel assessment procedure between the ap and sta before assigning the channel for traffic, thus reducing channel collision and improving the effectiveness of radio resources in wireless networks. additionally, the quality and availability of radio resources of overlaying networks would improve the usage of radio channels. this study assesses how spatial reuse, combined with different modulation with coding schemes and clear channel assessment, affects channel throughput. the results show that integrating spatial reuse can boost channel throughput by 18-20%, significantly enhancing network performance.
