What Is Satellite Internet?

Satellite internet delivers broadband access by transmitting radio signals between a dish at your home, a satellite orbiting Earth, and a ground station connected to the internet backbone. It is the only broadband technology that can reach virtually any point on the planet without underground cables or towers, making it the primary option for tens of millions of rural and remote households worldwide.

How Satellite Internet Works at a Basic Level

When you load a webpage over satellite internet, your router sends the request wirelessly to a small dish mounted on your roof or exterior wall. That dish beams the signal up to a satellite orbiting Earth, which relays it down to a ground station — also called a point of presence or gateway — that is physically connected to the broader internet. The response travels the same path in reverse: ground station to satellite, satellite to your dish, dish to your router, and finally to your device.

The key difference between satellite providers is how high their satellites orbit. Geostationary satellites (used by HughesNet and Viasat) sit at roughly 35,786 km above the equator, which means a single satellite can see an entire continent. Low-earth-orbit satellites (used by Starlink) fly at around 550 km, so many thousands of them are needed to provide continuous coverage, but signals arrive far faster because they travel a much shorter distance.

Who Is Satellite Internet For?

Satellite internet is primarily aimed at people and businesses in rural or remote areas where cable and fiber providers have not built infrastructure. In the United States alone, roughly 21 million people lack access to fixed broadband, and the majority of them live in areas where satellite is the only realistic high-speed option.

Beyond rural residences, satellite internet is widely used in several other scenarios:

• RVs and overlanders — Starlink's Roam plan allows subscribers to use the service anywhere within the coverage zone, including while traveling.
• Boats and maritime vessels — Starlink Maritime and similar plans cover ocean routes far beyond the reach of cellular or terrestrial networks.
• Remote work sites — Mining, forestry, and construction operations use satellite for connectivity where no other infrastructure exists.
• Emergency and disaster response — Satellite terminals can be deployed quickly when ground-based infrastructure is destroyed.

Typical Speeds and Latency

Satellite internet speed varies significantly depending on which generation of technology and which provider you use. Older geostationary services typically deliver between 25 Mbps and 100 Mbps download and 3–10 Mbps upload — adequate for video streaming and general browsing but often constrained by data caps. Modern low-earth-orbit services like Starlink have raised the bar considerably, with most residential customers seeing 50–200 Mbps download and 10–20 Mbps upload under typical conditions.

Latency is where the two generations differ most dramatically. Because geostationary satellites are nearly 36,000 km away, a signal must travel that distance twice — once up and once down — for every round trip, producing round-trip times of 500–700 milliseconds. That level of latency makes real-time gaming and video calls noticeably worse. Starlink's low orbit reduces round-trip latency to 20–60 ms, which is in the same range as many cable internet plans and good enough for gaming, video conferencing, and VoIP.

Availability

Because satellites orbit the entire Earth, satellite internet has the broadest geographic availability of any broadband technology. Geostationary providers offer continental coverage from a single satellite, though their beams may not reach polar regions above roughly 70 degrees latitude. Starlink's constellation of LEO satellites covers most of the landmass between about 75 degrees north and 75 degrees south, including all of North America, Europe, Australia, and most of South America, Africa, and Asia.

That said, satellite internet does require a clear view of the sky. Trees, buildings, and terrain features can block the signal path — a challenge that is greater for LEO services, where the dish must maintain line of sight to a constantly moving target across a wide arc of sky.

Satellite vs Other Broadband Technologies

The table below compares satellite internet against cable, fiber, and DSL on the metrics that matter most to everyday users. Note that satellite figures reflect modern LEO services like Starlink; geostationary services have lower speeds and much higher latency.

Is Satellite Internet Right for You?

If cable or fiber is available at your address, it will generally offer better value — faster speeds, lower latency, and lower monthly cost. But if you live in a rural area where those options do not reach, modern LEO satellite internet is a genuinely capable alternative. Starlink's residential plan, for example, supports 4K video streaming, video conferencing, and casual gaming simultaneously on multiple devices without the paralyzing latency that characterized older satellite services.

The main trade-offs to weigh are upfront equipment cost (typically $300–$600 for a dish and router kit), monthly service price (which runs higher than cable for comparable speeds), and susceptibility to temporary slowdowns during heavy rain or peak usage hours. For most rural users, those drawbacks are far outweighed by the alternative: DSL at 10 Mbps or no broadband at all.
