It said TerreStar's argument the FCC should focus on supporting use of existing mobile satellite service allocations to provide SCS services is moot since consumer devices today don't support MSS spectrum. SpaceX hasn't offered anything in the record to demonstrate its plans to modify its second-generation constellation to add a mobile satellite service system for SCS provision (see 2302080001) is feasible without resulting in harmful interference to their 2 GHz operations and plans, Dish Network and EchoStar told FCC personnel last week, recapping a meeting with an aide to Chairwoman Jessica Rosenworcel and a separate meeting with the Space Bureau.
