联邦通信委员会（FCC）已将6 GHz频段（5.925 - 7.125 GHz）分配给美国的非授权共享使用。通过不需要使用自动频率控制（AFC）机制的低功率室内（LPI）规则和需要使用自动频率控制（AFC）机制的标准功率（SP）规则来保护频带中的现任者。随着实施LPI规则的Wi-Fi 6 E AP的部署不断增加，研究密集LPI部署对固定链路的实际干扰潜力的研究有限，这仍然是现有企业的一个问题。我们在密歇根大学对密集的室内Wi-Fi 6 E网络进行了首次广泛的测量活动，其中包括步行，驾驶和无人机测量，以评估室外信标接收信号强度指标（RSSI），建筑物进入损耗（BEL），信道利用率以及建议的6 GHz客户端到客户端（C2C）模式的适当启用信号电平。我们在各种条件下的详细测量显示，通过双窗格低发射窗口，室外RSSI中位数在-75 dBm和-85 dBm之间，BEL在12 dB和16 dB之间，只有5%的室内基本服务集标识符（BSSID）在室外观察到。我们的总体结论是，干扰现任固定链路的概率是低的，但需要更多的研究，以确定适当的信号电平的C2C使能信号。
The Federal Communications Commission (FCC) has allocated the 6 GHz band (5.925 - 7.125 GHz) for unlicensed, shared use in the US. Incumbents in the band are protected via Low Power Indoor (LPI) rules that do not require the use of an Automatic Frequency Control (AFC) mechanism and Standard Power (SP) rules which do. As the deployment of Wi-Fi 6E APs implementing LPI rules have been increasing, there is limited research examining the real-world interference potential of dense LPI deployments to fixed links, which remains a concern for incumbents. We have conducted a first-of-its-kind extensive measurement campaign of a dense indoor Wi-Fi 6E network at the University of Michigan, which includes walking, driving, and drone measurements to assess outdoor beacon Received Signal Strength Indicator (RSSI), building entry loss (BEL), channel utilization, and appropriate enabling signal level for a proposed client-to-client (C2C) mode in 6 GHz. Our detailed measurements under various conditions show median outdoor RSSI between -75 dBm and -85 dBm, BEL between 12 dB and 16 dB through double-pane low-emission windows, and only 5% of indoor Basic Service Set Identifiers (BSSIDs) observed outdoors. Our overall conclusion is that the probability of interference to incumbent fixed links is low, but more research is required to determine the appropriate signal level for the C2C enabling signal.
