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
