An Assembly Line for Satellite Licenses: FCC Part 100, a New Space Bureau Chief and a 25 MHz Mid-Band Auction Proposal

Spectrum for Two Uses

A dual 5G and D2D allocation in 1675-1695 MHz is notable because it avoids a binary choice between terrestrial mobile and satellite use. Mid-band spectrum is highly valued by terrestrial carriers for its balance of coverage and capacity. Offering the band for both service types signals that the FCC sees D2D as a mainstream use of mobile spectrum and not a niche. It also raises design questions that an NPRM is meant to explore: how satellite and terrestrial systems will coexist, how licenses will be structured, and whether satellite operators or terrestrial carriers will end up holding the licenses.

That last question has commercial weight. At Silicon Valley Space Week, analyst Tim Farrar said carriers have concluded that relatively few people will pay for satellite-to-phone service. That comment came the same day the FCC approved Amazon's Globalstar transaction, which is covered elsewhere. If consumer willingness to pay is limited, carriers may value spectrum for terrestrial use more than for satellite use, which sets up a real contest in an auction with a dual allocation.

Industry Implications

Satellite Operators

Operators with large pending applications stand to benefit if Part 100 delivers consistent timelines. Smaller operators and new entrants may gain most, since they have fewer regulatory resources and are more sensitive to delay. Operators should read the final procedural rules closely to see how milestones, completeness reviews and amendments are handled, because those details determine whether the assembly line is actually faster.

D2D and Mobile Satellite Players

The SCS expansion and refreshed D2D rules support companies that connect satellites to ordinary handsets, including those that hold or are acquiring mobile satellite spectrum. The mid-band proposal adds a new potential spectrum source beyond existing mobile satellite bands. The business model question remains open. Farrar's remark that few consumers will pay suggests revenue may depend on bundling with carrier plans, wholesale arrangements, or emergency and coverage-extension use cases more than on stand-alone subscriptions.

Terrestrial Carriers

Carriers gain a potential 25 MHz of mid-band spectrum, but a shared allocation may come with conditions. They will weigh the value of the spectrum for 5G capacity against the obligations that come with satellite coexistence. Their participation in the rulemaking will shape how the dual allocation is defined.

Government and Federal Users

Mid-band spectrum in this range has historically involved federal users, and any auction proposal implies a transition or sharing arrangement. The summaries do not give details, so this is a point to follow in the NPRM text and comments filed by federal agencies and industry.

Law Firms, Investors and Advisors

A process rewrite creates demand for regulatory counsel and rewards firms that understand the new procedures early. Capital providers evaluating constellation projects will look at licensing timelines as a risk factor, and a more predictable process can lower that risk without eliminating it.

Key Stakeholders

• FCC Commissioners and the Space Bureau, now led by Courtney Reinhard, who will administer Part 100 and the D2D proceedings.
• Satellite Industry Association, which has publicly supported the SCS expansion and the Reinhard appointment.
• Satellite operators and constellation builders, both established and new entrants, who depend on licensing timelines.
• Mobile carriers and D2D partners, who compete and cooperate over mid-band and mobile satellite spectrum.
• Amazon and Globalstar, whose transaction the FCC approved the same day as the Farrar remarks.
• Congress, whose next session was discussed at the licensing panel and which holds authority over auction rules and funding.
• Legal advisors such as Greenberg Traurig, who are interpreting the new rules for clients.

Future Outlook

An NPRM is a proposal, so the next stage is a comment cycle in which carriers, satellite operators, federal agencies and public-interest groups will file positions. The main points of contention are likely to be coexistence and interference rules between 5G and D2D, the structure of the license (exclusive, shared, or tiered), the treatment of incumbent federal users, and the timing of any auction. The sources do not provide an auction date, and none should be assumed.

For Part 100, the key indicator will be measured processing times once the framework is in operation. Early cases will show whether the assembly-line description holds for complex constellation filings or mainly for routine ones. Reinhard's early priorities and staffing decisions will matter as much as the rule text.

The interaction with Congress is also a factor. The licensing panel discussed the next Congress, and any legislative changes to spectrum authority or agency resources could alter the pace. Operators should plan for a regulatory environment that is more standardized but still subject to political and budgetary shifts.

A possible cascading effect is on the economics of D2D. If mid-band spectrum becomes available for satellite use, the technical case for D2D improves, but Farrar's point about consumer willingness to pay remains the commercial test. Spectrum access and licensing speed are necessary conditions, not sufficient ones.

Key Takeaways

• The FCC voted on October 30, 2026 to advance an NPRM to auction 25 MHz at 1675-1695 MHz with dual 5G and D2D allocations.
• Part 100 is designed to make satellite licensing more standardized, and its real effect will show up in actual processing times.
• Courtney Reinhard takes over as Space Bureau Chief, and her priorities will shape how the new rules are applied.
• Analyst Tim Farrar said carriers see limited consumer willingness to pay for satellite-to-phone service, which makes the shared allocation commercially contested.
• Next steps are the comment cycle on the NPRM and early performance data from Part 100.
