Identify a spectrum band and there is a satellite tv for pc operator all for it, commented Elizabeth Quintana, principal, house authorisation – coverage at Ofcom. “We undoubtedly stay in fascinating occasions.”
Quintana was talking throughout a panel session on the current NTN Integration Discussion board hosted by RCRTech, when she and different coverage consultants outlined their approaches to spectrum optimization amid rising telco and satco curiosity in non-terrestrial networks (NTN) and direct-to-device (D2D) providers.
Her remark highlights that there is no such thing as a such factor as a “quiet” band anymore. If a frequency band provides appropriate propagation or capability, somebody within the satellite tv for pc sector is already outlining a marketing strategy for it. For UK regulators, which means staying open to experimentation whereas maintaining a tally of long-term competitors.
Additionally on the panel was Arpan Sura, a senior counsel to Federal Communications Fee (FCC) chairman Brendan Carr and chief AI officer. Different panelists included Julia Criado, head of division of spectrum planning and administration on the Ministry for Digital Transformation and of Civil Service in Spain, and Audrey Allison, senior coverage analyst, Heart for House and Coverage Technique at The Aerospace Company.
The message from the panel was clear: D2D is forcing regulators to rethink their approaches to which entities can use which bands, from the place and below what guidelines. It’s blurring the road between conventional cell satellite tv for pc service (MSS) bands and terrestrial cell (IMT) bands, creating new regulatory challenges across the coexistence of providers, cross‑border coordination and licensing fashions for shared or repurposed spectrum.
Diff’hire strokes
The panel additionally highlighted variations between the assorted nationwide and regional methods. As an example, Spain is erring on the cautious facet for now. Criado stated managed trials are being carried out particularly with Starlink on the two.6GHz terrestrial cell band, “and these trials permit us to higher perceive how the service works.”
The UK is taking a broadly pragmatic strategy. Quintana noticed that the nation has been “actually eager to allow non‑terrestrial networks to develop each our broadband and cell protection. We’re very lucky that now we have an excellent terrestrial laydown… however we have been one of many first international locations to allow [NGSO FSS], and extra just lately now we have enabled direct‑to‑system satellite tv for pc providers to assist complement cell within the UK, so that is direct‑to‑system utilizing IMT spectrum.”
In distinction, the US has adopted a extra aggressive stance, enabling D2D by a landmark 2024 framework that opens terrestrial bands to satellites, clarifies MSS rights, green-lights massive constellations and even probes the usage of core Wi‑Fi spectrum. As commented by Sura, it’s pursuing an “all‑of‑the‑above” spectrum technique.
On the identical time, he warned that strikes by the European Union to earmark two-thirds of the European 2GHz MSS spectrum might power the US to rethink its long-standing coverage of reciprocity and openness.
In the meantime, the ITU’s subsequent World Radiocommunication Convention (WRC) takes place in 2027. Allison has appreciable expertise with these landmark occasions, having served as committee and subcommittee chair at earlier WRCs.
She famous that present radio rules didn’t envisage a world the place spectrum allotted “to be used on the bottom” could be reused from house for mass‑market D2D. In essence, agenda merchandise 1.13 at WRC‑27 is successfully an effort to retrofit the principles. It explores whether or not satellites must be allowed to attach on to unusual cell phones utilizing the identical spectrum utilized by terrestrial cell networks.
The examine covers 694/698MHz as much as 2.7GHz, or spectrum that’s already used or recognized for terrestrial 4G/5G cell providers. Round a dozen particular preparations are below examine, and each certainly one of them has incumbents: cell networks, radar, Earth exploration, aeronautical telemetry and extra.
But nonetheless disruptive NTN and D2D seem proper now, WRC‑27 is a part of a steady strategy of adapting the principles.
“The gorgeous factor about these radio rules is we incrementally change them each 4 years… We’re at all times tinkering with them, and we’ll preserve doing so sooner or later,” Allison stated.
