- 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
