Even Worst-Case V-band NGSO Operations Won't Affect UMFUS, Boeing Says

Non-geostationary orbit satellite operations in worst-case rain conditions in the 37.5-40 GHz band have negligible impact on upper microwave flexible use service (UMFUS) operations, said a Boeing technical analysis given to the FCC International Bureau Satellite Division. An ex parte filing Wednesday in docket 14-177 recapped a call with division personnel about the analysis, which said modeling shows the effect on UMFUS is less than 0.65 dB. The call included division Chief Jose Albuquerque and Boeing engineers. The firm is seeking FCC approval for a V-band mega-constellation (see 1606230050).
