美国联邦通信委员会（FCC）已通过新的规则，开放6 GHz频段的非授权接入，因为无线网络的需求不断增加。新的裁决通过6 GHz频带中的功率谱密度（PSD）限制来限制操作，该功率谱密度限制不同于5 GHz频带中的独立于信道带宽的总平均功率。新的功率规则影响了无线局域网中的传输范围，并且接入点（AP）和站（STA）的不相等功率也影响了系统性能。在本文中，我们分析了Wi-Fi分布式协调功能（DCF）的吞吐量与两个物理（PHY）层的考虑，包括在5和6 GHz频段的不同功率规则，以及AP和STA之间的不平等的功率设置。据我们所知，这是第一项分析Wi-Fi在6 GHz频段和不相等功率设置下的跨层性能的工作。使用ns-3模拟，我们验证我们的吞吐量分析结果，并显示相关的见解。
US Federal Communications Commission (FCC) has adopted new rules to open the 6 GHz bands for unlicensed access as the increasing demand for wireless networks. The new ruling limits operation by a Power Spectral Density (PSD) limit in 6 GHz bands that differs from the total average power independent of the channel bandwidth in 5 GHz bands. The new power rules impact the transmission range, and the unequal power of the Access Points (AP) and stations (STA) also impact the system performance in wireless local area networks (WLANs). In this paper, we analyze the throughput of Wi-Fi distributed coordination function (DCF) with two physical (PHY) layer considerations, including the different power rules in 5 and 6 GHz bands as well as the unequal power setup among APs and STAs. To our best knowledge, this is the first work to analyze the cross-layer performance of Wi-Fi in 6 GHz bands and unequal power setups. Using ns-3 simulations, we validate our throughput analysis results and show the related insights.
