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
