Amazon Argues 17 GHz Coexistence With Space Bureau

Existing power flux density restrictions in the 17.8-18.3 GHz will address concerns fixed service (FS) operators have about allocating the 17 GHz band to fixed satellite service, representatives of Amazon's Kuiper told FCC Space Bureau staffers per a docket 20-330 filing Friday. Non-geostationary orbit FSS already has 17 GHz band access in Europe and Africa and interference-avoidance measures used in adjacent bands should do the same in the 17 GHz band and allow NGSO FSS operators to coexist with other authorized users in the band, they said. Amazon said FS operations in the 17.7-17.8 GHz band will be less likely to get interference than in the adjacent 17.8-18.3 GHz band because the 17 GHz band is less used by FS. It said its own dynamic interference simulations show aggregate interference to FS system receive antennas being well below ITU recommendations.
