Vodafone and AST SpaceMobile’s European Playbook: Dissecting the Ofcom Filing
A regulatory filing reveals the strategic architecture behind Europe’s homegrown satellite broadband bet
As is often the case, much credit is owed to the “Space Mob” and several members whose technical expertise probably ensures more is revealed about the end state of the constellation than AST SpaceMobile and Partners’ would like. In this instance, special thanks to @CytoplasmicANA for flagging the filing and additional insights from @CatSE___ApeX___ - all would be well-served to read his posts from today (1/27/26) regarding potential “1:1 spectrum reuse.” This would be a truly transformational turn for the constellation.
Last week, Vodafone and AST SpaceMobile submitted a joint response to Ofcom’s “Call for Input: Future use of the 2 GHz MSS band.” While regulatory filings rarely make for exciting reading, this one is an exception. It provides the clearest public window yet into how Vodafone and AST SpaceMobile are positioning SatCo to win the upcoming pan-European spectrum allocation and, by extension, to challenge SpaceX’s Starlink Direct-to-Cell ambitions on the continent.
The filing confirms parallel regulatory engagement at both UK (Ofcom) and EU (European Commission) levels, discloses new commercial traction with European MNOs, and lays out concrete technical specifications for the service. Here’s what investors and industry observers should take away.
The Regulatory Chess Board: UK and EU in Tandem
Perhaps the most significant disclosure is that Vodafone and AST SpaceMobile are actively engaged in parallel regulatory processes across the UK and EU. The filing explicitly states:
“Vodafone Group and AST SpaceMobile have been engaging closely with the European Commission and the RSPG to understand and comment on the arrangements for the award of the 2GHz MSS spectrum ahead of 2027. We responded to the Commission’s recent Targeted Consultation on the matter.”
That confidential submission to the European Commission was not made public, but the companies offered to share it with Ofcom. This suggests a coordinated strategy: build regulatory momentum across both jurisdictions simultaneously, with aligned arguments, timelines, and commitments.
The timing is notable as the current 2GHz MSS licenses expire in 2027, creating a once-in-a-generation opportunity to reallocate this spectrum. The incumbent licensees, Inmarsat and EchoStar (formerly Solaris Mobile/S-band), have been roundly criticized for underutilizing the band. The European Commission’s 2024 review acknowledged as much. Vodafone and AST SpaceMobile are clearly positioning SatCo as the solution to that failure.
SatCo: The European Super-Wholesale Model
The structural choice of a Luxembourg-headquartered joint venture operating as a wholesale provider is deliberate. Rather than competing directly with Europe’s mobile operators, SatCo will supply satellite backhaul capacity to all European MNOs who want it. This “super-wholesale” approach serves multiple strategic purposes:
First, it maximizes addressable market. By offering wholesale access, SatCo can theoretically serve the entire European mobile subscriber base, approximately 500 million users, rather than just Vodafone’s customers. The filing notes the UK alone has 88.4 million mobile devices that could benefit.
Second, it builds a coalition. The filing discloses that SatCo has signed Memoranda of Intent with six additional MNO groups beyond Vodafone’s operating companies, representing over 220 million subscribers across 21 European states. While MOIs are non-binding, they represent meaningful commercial interest and political backers. When the European Commission evaluates competing applications, an applicant backed by the continent’s major carriers will carry substantial weight.
Third, it addresses the sovereignty question. The filing repeatedly invokes European digital sovereignty, describing SatCo as “a solution that directly meets Europe’s critical needs and sovereign priorities, securely and cost-effectively in the current global geopolitical climate.” This is pointed language. SpaceX is American. AST SpaceMobile is also American, but the joint venture structure has European headquarters, European carrier partners, and European regulatory engagement. This creates a defensible narrative of local ownership and control. And, no 100%-owned constellation is anywhere in the works in the next few years with the technical capabilities to compete with Satco or Starlink. The EU will need to choose between a party with aligned interests and some American ownership or purely foreign/American ownership, or fall years behind technologically.
The implicit contrast with Starlink runs throughout the document. While SpaceX is never named, phrases like “home-grown European D2D offering” and “sovereign, secure and resilient communications” are unmistakably designed to differentiate SatCo from a vertically-integrated American competitor.
Technical Specifications: What the Network Will Actually Deliver
The filing provides unusually concrete technical specifications, likely because Ofcom requested evidence of deployment capability. Key figures:
Spectral efficiency: 3 bits per second per Hertz (bps/Hz) on the downlink using SISO (Single Input Single Output) configuration. This rises to 6 bps/Hz with the planned introduction of MIMO (Multiple Input Multiple Output) as more satellites are launched.
Throughput per beam: With the requested 2x15 MHz allocation and SISO configuration, each beam can deliver 45 Mbps downlink and 22 Mbps uplink peak throughput. This is mobile broadband, not just messaging.
Frequency reuse: AST SpaceMobile’s phased array antenna system and beam forming technology enable “full (1:1) frequency reuse” meaning the same frequencies can be used simultaneously across thousands of beams per satellite without interference. This is the core technological differentiation versus competitors using older satellite architectures.
Coverage: 100% geographic coverage of Europe, including Nordic regions.
Compatibility: Works with standard, unmodified 4G and 5G smartphones. No special hardware required on the consumer side.
The MIMO upgrade path is important. While 3 bps/Hz is respectable, 6 bps/Hz with MIMO would represent substantial capacity improvement, effectively doubling throughput per Hz of spectrum. The filing notes this capability will be enabled as more satellites are launched, suggesting ongoing constellation expansion beyond the initial commercial deployment.
The Border Problem: Why 2GHz MSS Matters
A key argument in the filing concerns the limitations of using terrestrial mobile (IMT) spectrum for satellite services. While AST SpaceMobile satellites can operate on MNO partners’ existing IMT frequencies, and will do so for the initial UK launch in 2026, these frequencies have significant constraints:
Border restrictions: IMT spectrum is nationally licensed. At borders, operators must coordinate to avoid cross-border interference. The filing notes that IMT-based D2D services “operate under ITU Radio Regulations article 4.4 and will therefore be especially restricted in border areas.”
Inconsistent allocations: Different MNOs in different countries hold different spectrum portfolios. The user experience would vary depending on what spectrum the local partner can contribute.
Feature deployment complexity: Rolling out new capabilities (6G, specialized encryption, broadcast mode for emergencies, IoT features) would require coordination across fragmented national spectrum holdings.
The 2GHz MSS band solves these problems. It’s harmonized across Europe, enabling seamless cross-border signals. For use cases like pan-European logistics, transport, emergency services, and roaming consumers, this harmonization is genuinely valuable. The filing makes this case explicitly:
“Only the 2GHz MSS frequencies are harmonised and able to provide seamless cross-border signals across UK and its neighbours - assuming the UK and the EU take an aligned approach on licence award.”
This framing positions 2GHz MSS as a complement to, not a replacement for, MNO spectrum. The combination of national IMT spectrum (for in-country capacity) plus harmonized MSS spectrum (for cross-border seamlessness and consistent service quality) is the technical architecture SatCo is proposing.
Consumer Research: Quantifying Demand
The filing cites primary research conducted across 5,000 consumers in nine Vodafone markets. Key findings:
· 67% of users reported connectivity issues with their current mobile service
· 73% expressed willingness to pay for the proposed satellite-based service
· 42% said the service would make them feel safer
· 38% said it would make a big difference to their lives
These numbers are striking, though the methodology isn’t disclosed. What price point was tested? How was the service described? Were respondents shown competitive alternatives? The filing doesn’t say.
Still, the directional signal is useful. Nearly three-quarters of surveyed consumers expressed interest in paying for satellite backup connectivity. That’s a larger addressable market than many skeptics have assumed. It suggests the service won’t be limited to niche use cases (rural coverage, emergency calling) but could see meaningful uptake among mainstream urban and suburban users who simply want more reliable connectivity.
Timeline and Spectrum Request
The deployment timeline is aggressive but credible:
· 2026: UK service launch using terrestrial mobile spectrum
· 2027/28: 2GHz MSS band services operational (assuming successful spectrum award)
The spectrum request is for a minimum of 2x15 MHz, or the amount necessary to achieve the economies of scale, trunking efficiencies, and unit economics that would enable mass-market affordability.
On license duration, the filing suggests 18 years as a baseline (matching the previous MSS license term) but expresses interest in longer tenure, noting that “Ofcom has solved the licensing certainty question for MNOs in the UK by offering perpetual licences, and this might be a suitable long-term ambition also for MSS licences.”
The argument for long license terms is straightforward: LEO satellites have 7-10 year useful lives, so any viable business case requires confidence in replenishment. Security of tenure enables the capital investment needed to maintain and upgrade the constellation over decades.
What This Means for the Investment Case
For AST SpaceMobile investors, this filing is incrementally positive. It demonstrates:
1. Active commercial traction. Six MNO MOIs representing 220 million subscribers is real momentum. These aren’t theoretical discussions – they’re documented commercial interest from named parties.
2. Coordinated regulatory strategy. Parallel engagement with UK and EU regulators, with aligned submissions and arguments, suggests sophisticated execution.
3. Technical credibility. The willingness to put specific spectral efficiency numbers and throughput figures in a public regulatory filing indicates confidence in the technology.
4. Strategic positioning against Starlink. The sovereignty narrative, wholesale structure, and coalition-building approach create defensible differentiation in a European regulatory context.
The key risks remain execution (can AST SpaceMobile actually launch enough satellites, on time?) and competition (will regulators award spectrum to SatCo, or to other applicants?). But this filing suggests the strategic architecture is sound and the commercial interest is real.
For Vodafone investors, the calculus is different. The SatCo joint venture represents optionality on a potentially transformative technology, but it’s not yet material to the overall business. The more interesting question is whether satellite backhaul capability could eventually become a competitive necessity rather than a differentiator. If so, Vodafone’s early positioning would be valuable insurance.
The Bigger Picture
The 2GHz MSS allocation decision, expected in 2027, will be one of the most consequential spectrum awards in recent European telecom history. The outcome will shape whether Europe develops indigenous satellite broadband capability or becomes dependent on American infrastructure.
Vodafone and AST SpaceMobile are making a clear bet: that European regulators, given a credible homegrown alternative, will prefer it to further entrenching US tech dominance. The filing is their opening argument. The next 18 months will determine whether that argument prevails.
