This is from a document presented at the "FCC Office of Engineering &
Technology Meeting," dated May 25, 2023. - Moderator

PG&E Concerns well documented on the Record:

* Over 100 incumbents (including PG&E) have voiced concerns with
Unlicensed Use of 6 GHz

* Many concerns included technical analysis and papers showing basis for
concerns

* 6 Real-World tests filed, all show impact to licensed microwave link’s
Fade Margin (FM)

* Latest is FirstEnergy/EPRI testing and analysis showing 4 dB
impact to FM from consumer deployed LPI APs at 2% penetration to
total APs

* Wi-Fi 7’s 320MHz channels will exacerbate the effect

* Impact to FM increases annual unplanned outage time (see graph based
on TIA-10)

* PG&E Operations would be significantly impacted at these levels of
interference: Commissioned study of Impact vs Penetration
