What is it about?
The 6 GHz frequency band (5.925 GHz - 7.125 GHz) has been allocated in the US for unlicensed, but shared use. There remain concerns that widespread deployments of Wi-Fi 6E in the band may interfere with incumbent fixed links. This paper presents the first results from an extensive measurement campaign of a dense Wi-Fi 6E deployment at the University of Michigan. We demonstrate that the probability of interference to fixed incumbents in the area is very low.

Why is it important?
The 6 GHz rules were developed without any real-world data. However, as deployments in 6 GHz proliferate, it is important that research is conducted to verify whether the rules are conservative, just right or can cause interference to incumbents. This paper presents the first such results and will inform future rule-making in this and other frequency bands.
Perspectives
Performing the measurements and analyzing the data collected was a learning experience for the students, many of whom where performing this type of research for the first time. Understanding the performance of real-world wireless deployments is crucial to developing the next generation of wireless systems that improve the end-user performance, especially in shared spectrum environments.
