Non Terrestrial Network (NTN
Satellite 2024 conference: Are Satellite and Cellular Worlds Converging or Colliding?
Converged terrestrial and satellite connectivity is a given, but the path is strewn with unknowns and sizable technological and business challengers, according to satellite operator CEOs. Hopefully, 3GPP Release 18 will contain the necessary specifications for it to be implemented as we explained in this IEEE Techblog post.
During Access Intelligence’s Satellite 2024 conference in Washington DC this week, Viasat CEO Mark Dankberg said satellite operators must start thinking and acting like mobile network operators, creating an ecosystem that allows seamless roaming among them. Terrestrial/non-terrestrial network (NTN) convergence requires “a complete rethinking” of space and ground segments, as well as two to three orders of magnitude improvement in data pricing, Dankberg said. Standards will help get satellite and terrestrial to fit together, but that evolution will happen slowly, taking 10 to 15 years, Iridium CEO Matt Desch said. It remains to be seen how direct-to-device services will make money, he added. Satellite-enabled SOS messaging on smartphones “is becoming free, and our satellites are not free — we need to make money on it some way,” Desch added.
The regulatory environment around satellite has changed tremendously during the past decade, with the FCC very oriented toward mobile networks’ spectrum needs and now satellite matters making up most of the agenda for the 2027 World Radiocommunication Conference, Desch said. However, there will be regulatory challenges to resolve in satellite/terrestrial convergence, he predicted. There are significant synergies in having a 5G terrestrial network and satcom assets under one roof, he said. Blurring the lines between terrestrial and non-terrestrial makes it easier for manufacturers to build affordable equipment that operates in both modes, Desch concluded.
That inevitable convergence is being driven by declining launch costs, maturing technologies and improved manufacturing, all of which make non-terrestrial network connectivity more economically competitive, said EchoStar CEO Hamid Akhavan. He said the EchoStar/Dish Network combination (see 2401020003) was driven in part by that convergence, consolidating EchoStar’s S-band spectrum holdings outside the U.S. with Dish’s S-band holdings inside the country. The deal also melds Dish’s network operator expertise with Hughes’ satellite expertise.
Wednesday Opening General Session: Are Satellite and Cellular Worlds Converging or Colliding?
To ensure space’s sustainability, missions must follow the mantra of “leave nothing behind,” sustainability advocates said. Space operators should have more universal protocols and vocabulary when exchanging space situational awareness data, as well as more uniformity in what content gets exchanged, said Space Data Association Executive Director Joe Chan. When it comes to space sustainability, clutter isn’t necessarily dangerous, and any rules fostering sustainability should avoid restricting the use of space, he said. Space lawyer Stephanie Roy of Perkins Coie said a mission authorization framework covering space operations that fall outside the regulatory domain of the FCC, FAA and NOAA is needed. Space operators and investors see sustainability rules as inevitable and want to ensure they allow flexibility and don’t mandate use of any particular technology, she added. Many speakers called for a “circular economy” in space, with more reuse of materials via refueling, reuse or life extension.
Separately, space sustainability advocates urged a mission authorization regulatory framework and universal use of design features such as docking plates enabling on-orbit serving or towing. Meanwhile, conference organizers said event attendance reached 14,000.
Also, ITU Secretary-General Doreen Bogdan-Martin urged the satellite industry to join ITU’s Partner2Connect digital coalition aimed at addressing digital divide issues, particularly in the least-developed nations and in landlocked and small island developing countries. The digital divide “is right up there” with climate change as a pressing issue for humanity, said Bogdan-Martin. She noted the coalition has received $46 billion in commitments, with a target of $100 billion by 2026.

SatCom market services, ITU-R WP 4G, 3GPP Release 18 and ABI Research Market Forecasts
Satellite Communications (SatCom) market services will include fixed broadband Internet access, satellite Internet of Things (IoT), and Non-Terrestrial Network (NTN) mobile (satellite-to-cell services). These services will experience growth due to more satellite players launching networks in Low Earth Orbit (LEO), alongside an increasing interest in terrestrial and satellite network convergence.
The market is expanding rapidly and major players are quickly recognizing its potential. While satellite networks are experiencing rapid changes due to innovations in small satellites and nanosatellites, Software-Defined Networking (SDN) applications, High Throughput Satellites (HTS), and inter-satellite links, terminals on the ground continue to see growth, with Very Small Aperture Terminals (VSAT) SatCom solutions maintaining dominance in the market.
According to Research & Markets, the SATCOM equipment market is valued at $22.6 billion in 2023 and is projected to reach $38.7 billion by 2028, at a CAGR of 11.3% from 2023 to 2028. Based on frequency, the multiband frequency is projected to register the highest during the forecast period 2023-2028.

ITU-R Working Party 4B (WP 4B) is responsible for recommendations related to: Systems, air interfaces, performance and availability objectives for FSS, BSS and MSS, including IP-based applications and satellite news gathering.
WP 4B has a working document which is a preliminary draft new Report ITU-R M.[SAT IOT] – Technical and operational aspects of satellite Internet of Things (IoT) applications, a work plan and working document on Work plan for development of a preliminary draft new Report ITU-R M.[DEVELOPMENT AND TECHNOLOGY TRENDS FOR THE SATELLITE COMPONENT OF INTERNATIONAL MOBILE TELECOMMUNICATIONS]. WP5D last meeting was July 2023, but the following meeting won’t be till April 29 to May 5, 2024!
Yet the real SatCom air interface specifications work is being done by 3GPP, under the umbrella term of NTN:
3GPP Release 17 introduced new network topologies that are based on High-Altitude Platforms (HAPs) and LEO and Geostationary Orbit (GEO) satellites. Crucially, these laid out the foundation for satellite IoT and NTN mobile as Release 17 extended the cellular IoT protocols, LTE-M and Narrowband (NB)-IoT for satellites. This enabled two new standards for satellite networks, IoT-NTN and New Radio-NTN (NR-NTN). SatCom with individual mobile devices will close gaps in the terrestrial cellular networks to provide global connectivity. It will target issues like unreachability and service continuity in underserved regions and improve network resilience around the world.
The discussion items in the upcoming 3GPP Release 18 are expected to enhance NTN Mobile and Satellite IoT as key satellite enabled services. While Release 17 established the standards for IoT-NTN and NR-NTN, Release 18 will evolve both those specifications for IoT and satellite-to-mobile broadband connectivity. For NR-NTN, there are plans to run NR-NTN on Radio Frequency (RF) spectrum above 10 Gigahertz (GHz) to serve the aerospace and maritime industry, alongside businesses and buildings (with building-mounted devices). Release 18 is also expected to include enhancements in satellite backhaul, specifically the dedication of more spectrum for Mobile Satellite Services (MSS), with approximately 80 Megahertz (MHz) of uplink in the L-band and downlink in the S-band.
At the same time, improvements targeted toward Fixed Satellite Services (FSS) will be brought about by Release 18 as well, with the consideration of more bands in the Ka frequency bands for downlink (17.7 – 20.2 GHz) and uplink (27.5 – 30 GHz). While the specifics of 3GPP Release 18 are still in development, 3GPP has already established the boundaries of Release 18 that will benefit the SatCom market. Furthermore, with the recent mergers of Eutelsat and OneWeb in 2022 and Viasat and Inmarsat in 2023, in addition to the launch of Infrastructure for Resilience, Interconnectivity and Security by Satellite (IRIS2), a project endorsed by the European Union (EU) in 2022 to enhance connectivity throughout the EU, more partnerships and agreements are expected to arise ahead of the official launch of 3GPP Release 18 in 2024.
ABI Research says that 3GPP Release 18 aims to unlock new capabilities toward the evolution of 5G-Advanced and establish new regulatory requirements, along with new bands, while optimizing satellite access performance. The market research firm forecasts the market value for worldwide SatCom to be US$94.9 billion by 2027 (MD-SATCC-102). The growth of NTN mobile, in addition to broadband, will drive the market moving forward, with special mention of NTN mobile revenue likely to shoot from 0.2% of the total revenue in 2023 to 8.8% of the overall SatCom revenue by 2027. ABI Research recognizes that greater value has been placed on the protocols, such as 3GPP Release 18 and beyond, that will develop and nurture the SatCom space.
Strategic partnerships between terrestrial and NTN operators, solution providers/Communication Service Providers (CSPs), and wireless end-user equipment vendors are currently on the rise and will be critical in expanding the ecosystem and market toward 2027. For instance, MediaTek and Qualcomm have partnered with Inmarsat and Iridium, respectively, to target the NTN mobile market.
Meanwhile, AST SpaceMobile has agreements with AT&T, Rakuten Mobile, and several other mobile network operators. Where satellite IoT is concerned, CSPs like Deutsche Telekom have established partnerships with Intelsat and Skylo, whereas Telefónica and Sateliot are working together to trial satellite IoT connectivity. While partnerships are a good indicator of SatCom’s market potential, it is important that operators consider differentiated and unique product offerings for clients.
The value proposition that SatCom players can offer their target market will be essential for this process. Some examples might include integrated end-to-end IoT solutions for maritime, offshore connectivity, or end-to-end NTN mobile solutions that marry NTN hardware and software for satellite connectivity. Nonetheless, the creation of new value added services will benefit from 3GPP Release 18, in addition to driving the overall momentum and agenda of the Satellite Communications market.
