| AST SpaceMobile | AST SpaceMobile supports broad authorization of SCS use of the Upper C-band to provide direct-to-device services, arguing it will expand broadband connectivity and bridge the digital divide. The company conditions this support on retention of existing -120 dBW/m²/MHz out-of-band emissions power flux density limits to mitigate interference. Additionally, AST SpaceMobile urges the Commission to allow terrestrial licensees to satisfy network performance requirements through deployment of broadband-capable SCS networks.

| AT&T | AT&T opposes premature changes to Lower C-band spurious emissions limits, arguing the Commission should focus on the Upper C-band auction deadline and defer any coexistence framework review until after July 2026 when more clarity exists about the post-auction environment. AT&T supports adopting a uniform 4-watt EIRP limit for mobile devices across both Lower and Upper C-band to increase coverage and capacity. AT&T argues that any future Lower C-band review should be guided by three principles: full grandfathering of existing equipment, minimal burdens on future deployments, and Lower C-band spurious emissions limits no more stringent than Upper C-band limits due to greater spectral separation from radio altimeters.

| Aerospace Industries Association | The Aerospace Industries Association, on behalf of aviation stakeholders, asserts that aviation safety is the top priority and requires specific technical parameters for Upper C-Band deployment. The filing contends that the CTIA model contains significant inaccuracies and overestimates benefits while underestimating deployment complexity. AIA calls for FCC-FAA alignment on EIRP-based emission limits, harmonized technical parameters, extended Lower C-Band protections through 2028, and a deployment timeline consistent with Part 121/129 radio altimeter equipment retrofit deadlines.

| Airlines for America | A4A supports the Draft C-Band Order's rebate program for aircraft altimeter retrofits and broadly endorses its timeline and clearinghouse approach. However, A4A advocates for five targeted modifications: (1) FCC transparency on rebate program cost estimates; (2) clearer specification that rebates offset full retrofit costs and reflect acceleration efforts; (3) inclusion of spare altimeters within rebate eligibility; (4) rebate policies designed to avoid artificial supply shortages by incentivizing claims sequentially by FAA deadline; and (5) extension of aircraft eligibility from January 1, 2030 to September 30, 2030.

| Aviation Safety Coalition | The Joint Aviation Community (Boeing, AIA, GAMA, and other aviation stakeholders) met with FCC Commissioner Gomez's office to discuss aviation safety positions regarding the Upper C-band rulemaking. Their primary concerns are maintaining aircraft radio altimeter performance through coexistence measures, technical harmonization between FCC and FAA rules, implementation timelines for retrofits, and extension of Lower C-band voluntary commitments. The aviation industry submitted detailed technical parameters, retrofit timelines, and safety requirements aligned with previous joint aviation filings and FAA comments. [source] | 2026-04-22 |
| CTIA | CTIA supports adoption of the Draft Upper C-band Order, including its out-of-band emissions (OOBE) solution coordinated with the FAA, the -28.4 dBm/MHz/-46 dBm/MHz base station limits, and the -13 dBm/MHz mobile/portable limits. CTIA endorses the reasoned transition approach with cost reimbursement caps and safeguards on soft costs and financing charges, and urges rejection of requests that would expand reimbursement eligibility or weaken clearinghouse oversight structures.

| Intelsat | Intelsat supports some reallocation of the Upper C-band for terrestrial wireless use but insists that a sufficient portion must remain allocated for fixed-satellite service (FSS) operations to preserve content distribution and comply with Communications Act Section 316. The company also advocates for accelerated relocation incentive payments to facilitate spectrum clearing, opposes introduction of point-to-multipoint services in the FSS-retained band, and argues that FSS use should be preserved outside the contiguous United States.

| NCTA | NCTA discussed concerns that the increased 4-Watt effective isotropic radiated power limit applied to Lower C-band rules could negatively impact the adjacent CBRS band operating environment. NCTA identified potential paths for the Commission to ensure Lower C-band service rules would not degrade CBRS operations. NCTA emphasized that any such approaches would not affect Upper C-band service rules or the timing of the upcoming auction. [source] | 2026-07-17 |
| SES | SES commends the Draft Order's adherence to the Lower C-band framework and supports its direction for ensuring incumbent satellite operators can maintain substantially the same service. SES proposes specific revisions: (a) clarify cost reimbursement rules beyond the Final Transition Deadline of June 20, 2031; (b) adopt the same accelerated relocation payment step-down table used in Lower C-band for both Primary and Final deadlines; and (c) allow new licensees to begin service after the same prerequisites as Lower C-band, avoiding a "flash cut" to FSS service. SES also supports clearinghouse measures to accelerate claims processing and reimbursement. [source] | 2026-07-14 |
| SpaceX | SpaceX supports the draft C-band Order's buildout milestones requiring high-power, high-density, wide-area commercial mobile services and urges rejection of proposals for low-power or localized deployments like IoT. SpaceX advocates for technology-neutral satellite coverage to meet construction requirements in sparsely populated areas. SpaceX seeks further notice on Supplemental Coverage from Space (SCS) designation, reallocation of legacy FSS spectrum to higher-value use, and market access reciprocity with foreign operators, while opposing new bureaucratic authorization requirements for foreign SCS deployment.

| T-Mobile | T-Mobile supports reallocation of the Upper C-band for terrestrial broadband use with a unified regulatory framework harmonized with the Lower C-band (applying the same Part 27 licensing and technical rules). The company opposes accelerated relocation payments for satellite operators that exceed the timeline for radio altimeter upgrades (estimated 2031 at earliest), and opposes introducing mobile satellite services or shared-use mechanisms in the Upper C-band. [source] | 2026-02-19 |
| Verizon | Verizon urges the FCC to dismiss or deny petitions for reconsideration seeking changes to the Lower C-band rules. Verizon argues that aviation petitioners' claims are moot given successful Lower C-band deployments and ongoing radio altimeter upgrades. Verizon supports general affirmation of existing Part 27 Lower C-band technical rules with one exception: modification of the User Equipment power limit to 4 Watts for in-home fixed wireless access products, harmonized across the C-band.

| WISPA | The CBRS Ecosystem Representatives support the Commission's decision to open the Upper C-Band (3.98-4.2 GHz) for full-power exclusive licensed use. However, they express strong concern about a provision in the draft Upper C-Band Report & Order (¶72) that would increase mobile and portable device power limits in the Lower C-Band from 1W EIRP to 4W EIRP, citing potential interference to CBRS devices. They respectfully request deferral of this specific Lower C-Band power increase provision to a subsequent Further Notice of Proposed Rulemaking to allow time for technical impact analysis, while explicitly stating they are not asking for any modification to the Upper C-Band itself.

| Wireless Infrastructure Association | WIA supports auctioning no less than 180 MHz of Upper C-band spectrum for full-powered licensed commercial mobile terrestrial applications, with deployment rules consistent with the lower C-band rules (Part 27). WIA further requests the Commission collaborate with the FAA to expedite inclusion of these frequencies in the FAA's Colo Void Policy, aligned with the auction schedule, to enable rapid post-auction deployment.
