Summary

  • The FCC’s September circulated draft would add primary fixed-satellite downlinks to individually licensed gateway and feeder-link stations across 500 MHz at 42 GHz. Terrestrial fixed services would remain primary; mobile services would become secondary.
  • The draft leaves the 42 GHz “light licensing” design and its coordination database to a later proceeding. Until that framework exists, satellite applications would move through the FCC’s existing licensing rules.
  • The FCC says there are no current terrestrial deployments in the fixed or mobile allocations. The change therefore sets the terms for future entrants; it does not evict an operating network.

A satellite dish could receive first, a fixed microwave link could keep its primary status, and a future mobile network would have to accept a lower rank. That is the pecking order in the FCC’s circulated 42 GHz proposal.

The FCC’s September 9 fact sheet describes more than 1,000 MHz for satellite services across two bands. The 42–42.5 GHz portion is 500 MHz. The draft would add a primary fixed-satellite service downlink allocation for both geostationary and non-geostationary satellites. But access is tightly framed: earth stations would be individually licensed gateway and feeder-link sites. The draft declines blanket licensing for 42 GHz terminals.

Terrestrial fixed service keeps its primary allocation. The draft says site-based coordination and satellite power-flux-density limits could allow fixed links and satellite receivers to coexist. Mobile service takes the sharper cut: its allocation would move from primary to secondary, and mobile stations would have to protect fixed satellite and fixed-service sites. The FCC’s circulated text says no fixed or mobile terrestrial deployments currently use the band. That makes the change a rule for the next entrant, not a shutdown notice to a working network.

The draft’s own control room is not ready. It points to a “light licensing” system with automation and a third-party database for registering links and coordinating sites. The FCC says the record has not settled who would establish that database or manage it. It defers those mechanics to other or future proceedings. In the meantime, satellite applications would be processed under existing licensing rules. “Spectrum abundance” therefore arrives before the queueing system meant to manage shared sites.

The stakes are procedural as well as technical. A gateway’s coordinates can determine which fixed link must move, which site can transmit, and how a reported interference claim is investigated. A public, current database and a defined dispute route would turn the proposed hierarchy into an operating arrangement. Without them, every new site begins with a paper allocation and a coordination problem still waiting for its referee.

The FCC attachment is a circulated draft, with adoption and release lines blank on its cover. The released final order and its rule text are the missing record that would show whether these tiers survived and when they take effect.
