How Does Satellite Internet Work? Pros, Cons, Cost, and More

Satellite internet offers connectivity in remote locations where ground-based connections may not be available, allowing you to stay connected while living in or traveling far away from population centers. It’s different from ground-based internet in many respects, though, so it’s important to understand how it works before deciding if it’s right for you.

This guide explains how satellite internet works, its advantages and limitations, when you need it, and whether it’s worth the extra money and effort.

What Is a Satellite Internet Network?

A satellite network connects you to the internet via Earth-orbiting satellites instead of ground cables or cellular towers. These networks rely on several technologies:

• Satellite modem or router: A device that manages your internet sessions, exchanging data between your devices and the satellite panel.
• Satellite terminal or flat antenna: A panel or an antenna installed outdoors that communicates with the satellites in space, sending and receiving data via radio signal.
• Orbiting satellites: Space-based relays that transmit signals from your terminal to the network operations centers and vice versa.
• Network operations centers: Ground stations connecting the orbiting satellites to the internet.

How Does Satellite Internet Work?

Satellite networks combine space and ground stations to provide internet access. The whole process happens like this:

1. Device to modem: Your device (computer, console, or phone) sends the request to your satellite modem.
2. Modem to terminal: The modem converts your request into radio signals and passes it to the antenna or a dish, for example, a Starlink terminal.
3. Terminal to satellites: Your panel beams your signal to a satellite in orbit (around 350 miles for Starlink, and higher for other providers).
4. Satellite to ground station: The satellite sends your data down to a ground gateway connected to the provider’s network. It then forwards your request into the terrestrial internet through fiber-optic cables and network routers to reach the target web server (for example, the website you’re trying to load).
5. To the internet and back: Once the destination server receives your request, the response then returns along the same path in reverse, ending back at your device.

In essence, every time you load something online via satellite internet, the data makes a round-trip into space. This whole process happens quickly, but it does introduce more latency (delay) than terrestrial internet because of the long distances involved (especially for high-altitude satellites).

Pros and Cons of Satellite Internet Networks

Satellite internet works differently from ground-based internet service providers. Let’s see where this connection method stands out and falls short.

Pros of Satellite Internet

Satellite internet is useful primarily when wired networks are unavailable or limited.

• Rural or remote areas coverage: Satellites reach places without cable or fiber, extending your internet access to remote areas with poor coverage.
• Portable access: Compact terminals can provide you with internet access while you’re traveling, as long as you have a clear sky view (and the provider’s area coverage). This makes them great for RV travelers, van-lifers, truckers, or sailors who need connectivity on the move.
• Backup option: You can use satellite internet as a backup service since it has independent infrastructure that works during internet outages (provided you have power).
• Easy to configure: Modern satellite kits, like Starlink’s terminals, only need a clear line toward the sky to connect with the provider’s network.

Cons of Satellite Internet

Satellite networks also introduce limitations, mostly because you need a direct path between the terminal and the satellite.

• Weather sensitivity: Your connection quality can worsen significantly during storms, heavy rain, snow, or even thick clouds. This effect is commonly known as “rain fade.”
• Obstruction susceptibility: Buildings, trees, and other objects blocking the line of sight can cause extra delay and occasional disconnects.
• Expensive installation and use: Equipment and subscriptions are costly because the provider maintains orbiting hardware and specialized ground stations.
• High latency (ping): Satellite networks add a noticeable transmission delay because the data needs more time to travel to space and back.

How Does Satellite Internet Compare to Broadband and Other Connection Types?

The deciding factors are often cost and latency. Satellite networks are usually far more expensive to install and use. Besides, ground-based connection networks still have lower latency (even if not necessarily faster speeds).

Connection type	Max speeds	Delay	Availability	Cost estimates
Satellite Internet	250 Mbps	Very High	Most regions	Very high
DSL	100 Mbps	Moderate	Wide	Low to mid
Fiber	10 Gbps (10000 Mbps)	Very low	Limited	Mid to high
Cable	2 Gbps (2000 Mbps)	Very low	Wide	Mid
5G	1 Gbps (1000 Mbps)	Low to moderate	Wide	Low to mid
Fixed Wireless (4G)	150 Mbps	Moderate	Most regions	Low to mid

Who Needs Satellite Internet?

Satellite connection is not as fast or affordable as ground-based internet, but there are scenarios where you should consider satellite connection:

• If you live in isolated areas: Satellite internet works in rural areas and other remote places without other internet access options.
• If you’re a frequent traveler: You can use satellite terminals to maintain a web connection from your RV, boat, or mountain top.
• If you want disaster prevention: Keeping a satellite terminal in your household can help you stay online during infrastructure failures or times of crisis.
• If you have many customers: Ship crews and passengers use satellite links for communication during long voyages far from land-based networks.
• If you have remote employees: Businesses keep workers in isolated regions (like farms, construction sites, and mines) connected via satellite terminals.

Who Offers Satellite Internet?

Many companies offer satellite internet, but a few large players currently dominate the market. 

Starlink

Starlink uses a dense network of small Low Earth Orbit (LEO) satellites. They fly much closer to the planet than the geostationary satellites most other companies still use. LEO satellite systems automatically switch you between satellites, keeping your connection stable as they move across the orbit.

A shorter distance to Earth makes the connection well-suited for high-bandwidth tasks such as UHD streaming, video calls, and smooth gameplay. According to the 2025 Ookla Research report, the average Starlink speed nearly doubled from 2022 to 2025. However, it still trails some regulatory benchmarks for high-tier broadband.

Hughesnet

Hughesnet is a long-running satellite provider that uses a trio of geostationary satellites. The last satellite, Jupiter 3, launched in 2023 and broadened coverage to North and South America.

Their satellites sit much farther from Earth than Starlink’s LEO, which increases the delay significantly. The Ookla 2025 report states that Hughesnet’s average latency got to about 683 ms (from 1019 ms in 2022). It’s more than enough for web browsing, email, and light streaming, but too slow for latency-sensitive activities like online gaming and real-time collaboration tools.

Viasat

Viasat is a mid-budget geostationary satellite provider for US users. Based on Ookla’s 2025 data, the provider has been steadily improving its speeds over the last few years. It offers roughly the same speeds and latency as Hughesnet.

EarthLink

EarthLink uses other companies’ satellites to provide internet access. It means the signals flow through the partner infrastructure, and access is provided by this company. Coverage spans most of the US, but performance varies based on the partner’s network availability.

How Much Is Satellite Internet Per Month?

Satellite internet providers’ plans vary in price and coverage, but price isn’t the only critical factor when choosing a satellite provider.

Different subscription plans may offer different speeds, which determine how fast you can send and receive data. You should also ensure your plan offers low enough latency for any time-sensitive tasks, like fast-paced online gaming. Higher latency will introduce a significant delay between your actions and on-screen responses, so you probably want this to be under 100 ms to keep gameplay smooth.

Data policies also matter. Starlink and Viasat may slow you down after you consume a certain amount of data, giving priority to higher-tier customers.

Satellite provider	Starting price	Installation costs	Data limits	Average download speeds	Average latency	Coverage
Starlink	$40–$100	$400–$700 (depending on the terminal model)	Unlimited standard, optional priority tiers	100–110 Mbps (280 Mbps max)	40–100 ms	North America (US, Canada, Mexico), South America, Europe, Australia, parts of Asia and Africa
Hughesnet	$40–$100	Free install with lease, or $300–$500 (for equipment)	Unlimited standard, 100–200 GB (priority)	40–50 Mbps (100 Mbps max)	600–700 ms	North and South America
Viasat	$40–$70	$250–$350	150–850 GB	40–50 Mbps (150 Mbps max)	600–700 ms	US
EarthLink	$40–$70 (custom)	$300–$500	Limits vary by partner	25–40 Mbps (100 Mbps max)	500–600 ms	US

Note: While these details are correct at the time of writing, prices and plan details change regularly. You should double-check the provider’s site before making a decision.
