Exclusion Zones Necessitate Leaving 29.25-29.3 GHz Out of ESIM Use, Iridium Says

Instead of including the 29.25-29.3 GHz band as spectrum available for earth stations in motion, the agency should wait until industry someday develops methods for creating exclusion zones that would protect Iridium earth stations from ESIMs, Iridium told FCC International Bureau staffers, said a filing Monday in docket 17-95. It said the exclusion zone boundary issue is complicated by the fact the location and number of geostationary orbit ESIM terminals -- especially those for earth stations aboard aircraft -- will change, sometimes constantly.
