The satellite is only one part of that chain: antennas and onboard systems shape the radio or laser link, while user terminals, ground stations and gateways connect space traffic to people and terrestrial networks. Direct-to-cell services use a different user-side arrangement, communicating with compatible cellular devices instead of requiring each user to install a dedicated satellite broadband terminal.
How does a satellite connect to the internet?
A typical satellite connection is a sequence of links, not a single hop. A user’s equipment sends data to a satellite; the satellite routes or relays it toward another satellite or a ground station; and ground infrastructure passes it into terrestrial networks. The return path carries responses back to the user. The exact route depends on the network design and whether the satellite can communicate directly with a suitable ground station at that moment.

- At the user end: A dedicated broadband terminal, or in some direct-to-cell services a compatible cellular device, sends and receives the signal.
- Across the space link: Satellite antennas receive and transmit the signal. Onboard systems may process, direct or route traffic, depending on the spacecraft and network architecture.
- At the ground segment: Ground-station antennas and radio equipment communicate with satellites. Gateways connect that satellite traffic to terrestrial networks and internet infrastructure.
- Across the wider network: Terrestrial networks carry the data to its destination. A response travels back through the applicable ground, satellite and user links.
NASA’s SmallSat Institute describes the ground segment as the ground-based elements used to collect and disseminate satellite data, including terminals and antennas. Its Ground Data Systems and Mission Operations guidance calls this segment the gateway for getting satellite-collected data to users. The same architectural distinction applies to connectivity: a satellite link is useful only when the rest of the system can deliver its traffic where it needs to go.

Antennas that steer communication links
Antennas are a central part of the space hardware. A phased-array antenna uses an array of elements whose signals can be coordinated to direct a beam electronically. This can support steering without relying only on a mechanically moved dish. The technique is important where a satellite needs to maintain links as it moves relative to users, other spacecraft or ground stations.

One operator-specific example comes from Starlink’s 2024 report: it says each of its satellites uses five Ku-band phased-array antennas and three dual-band Ka-band/E-band antennas for customer connectivity. The report also describes custom silicon phased-array antennas on its Direct to Cell satellites. Those are the operator’s reported designs, not a standard specification for all satellite networks.
Onboard processing and routing
The antenna provides a communications link; onboard electronics determine how the spacecraft handles signals and traffic. Depending on the system, spacecraft may process signals or help route traffic between links. The ITU Journal’s 2024 overview of integrated satellite and terrestrial networks identifies onboard processing, dynamic beam hopping, high-frequency phased arrays, and adaptive inter-satellite links and routing among relevant technologies. These are architectural capabilities and areas of development, not features that should be assumed to exist in every satellite.
Beam hopping and adaptive routing help describe why the hardware layer is more than a radio pointed at Earth: networks have to allocate communications resources and move traffic across changing links. The particular capabilities and route available depend on the operator’s spacecraft and network design.

How are a user terminal, ground station and gateway different?
They occupy different points in the connection. A user terminal is the customer-side equipment that communicates with a satellite in a dedicated broadband setup. A ground station is a terrestrial site equipped to communicate with spacecraft. A gateway connects satellite traffic to terrestrial networks; it may be associated with ground-station infrastructure, but the terms do not mean the same thing.

The user terminal
A dedicated satellite broadband terminal links a home, business or other customer site to the space segment. Its antenna and radio equipment handle the local satellite connection. It is not the same as a gateway: the terminal is at the user end, while the gateway is part of the network’s connection back to terrestrial infrastructure.
The ground station and gateway
NASA’s small-satellite reference describes ground-station terminals as transmitters, receivers or transceivers, together with their antennas. For direct-to-Earth links, a station may use a high-gain parabolic antenna. Ground systems can also use phased arrays or optical equipment, depending on the mission and link.
After a ground station receives traffic, gateway and network equipment can pass it on to terrestrial systems. The location and number of ground sites, the links they support and the networks they connect are parts of the overall service architecture—not interchangeable names for the customer’s equipment.

A direct-to-Earth path connects a satellite with a ground station when the station is in view and the link is available. A relay architecture adds an intermediate link: a satellite can pass data to a relay spacecraft, which then communicates with a ground site or another network segment. NASA describes relay services as a way to bridge visibility gaps when direct ground communication is unavailable.

Relays can help maintain communications when a spacecraft cannot directly see a ground station, but they add another link and another part of the system that must work. Whether a network uses direct-to-Earth links, relays or a combination depends on its coverage, continuity and data-return requirements. A relay is a network component, not a user terminal or a synonym for a gateway.
Where do optical links fit alongside radio?
Most satellite communications discussed in this context use radio-frequency (RF) links. Optical communications add a laser link to the available toolkit. They can move large amounts of data, but they are not simply a drop-in replacement for every radio link: the equipment, pointing and link conditions are different, and an optical link still has to connect the right parts of the network.
NASA’s LCRD and ILLUMA-T work demonstrates a two-way optical relay using spacecraft and ground terminals. Separately, NASA’s 2023 LCRD overview reports that the TeraByte InfraRed Delivery (TBIRD) payload, launched on a CubeSat in 2022, achieved a 200 Gbps direct-to-Earth optical downlink. That figure is a result from a named NASA demonstration, not a typical broadband plan speed or a measure of what a consumer experiences.
NASA’s ground-systems overview says optical communications can deliver orders of magnitude more data per pass than RF communications in mission contexts. That comparison depends on system design and conditions; it does not establish a universal capacity, cost or performance advantage for every satellite network. Optical and radio links can serve different roles in an end-to-end system.

How does direct-to-cell change the user-side hardware?
Dedicated satellite broadband and direct-to-cell use different user-side assumptions. A broadband service uses a dedicated terminal at the customer site to communicate with the satellite. Direct-to-cell instead uses satellite equipment designed to communicate with compatible cellular devices, so a user does not necessarily need a separate satellite dish.
Starlink’s Direct to Cell page says its service works with compatible off-the-shelf CAT-1, CAT-1 Bis and CAT-4 modems without specialized additional hardware. Its stated plans rely on partners in approved countries. That description is not a guarantee that every phone, modem, plan or location is supported: service status, device compatibility and geographic availability are dependent on country and partner, and can change.
Direct-to-cell should not be treated as equivalent to dedicated satellite broadband. The two approaches use different user equipment and target different connection arrangements. A no-special-terminal claim describes the compatible device side; it does not mean there is no specialized satellite, ground or partner-network hardware behind the service.
Why does interoperability matter?
When networks use different spacecraft, frequencies, terminals and software, equipment that works with one provider may not automatically work with another. Interoperability is therefore both a hardware and a software challenge, particularly if users or systems need to move between satellite networks.

NASA’s PExT work explores wideband “polylingual” terminals and software-defined radios as possible enablers of roaming across more than one satellite-provider network. The aim is not a claim that seamless roaming is already universal; it is an approach to making terminals more adaptable across networks. Compatibility still depends on the supported bands, radio capabilities, software and network arrangements.
What do the reported user numbers tell us?
In its 2025 reporting, Starlink said more than 4.6 million new active customers connected during that year and that more than 12 million people had connected at least once through Starlink Direct to Cell. These are company-reported service-scale figures, not independent measurements. They illustrate the scale reported by one operator, but do not describe the hardware configuration, performance or availability of satellite services generally.
What the hardware explains—and what it does not
The physical connection depends on coordinated equipment across space and Earth: satellite antennas and onboard systems, a user-side link, ground stations or relays, and gateways into terrestrial networks. Optical links and direct-to-cell designs change parts of that chain, but do not remove the need for an end-to-end network.
The architecture alone does not establish which consumer terminal is best, what service is available at a particular address, or what speed a particular user will receive. Those answers depend on the provider, service, location, compatible equipment and operating conditions. NASA’s mission demonstrations and operator-reported hardware details explain how particular systems work; they should not be read as universal consumer specifications.
