Main » Internet » Starlink: What is it, how does it work, and what is SpaceX's satellite internet for?

Can you imagine having access to high-speed internet anywhere in the world, wherever you are, even if there's no fiber optic coverage or mobile data isn't available? Well, this is now a reality thanks to Starlink, the revolutionary satellite internet system driven by Elon Musk and SpaceX. If you've ever heard of those famous "satellite constellations" and are wondering if Starlink could solve your connection problems, here's how. All you need to know in a clear, updated and much more accessible way.

In this complete guide you will discover What is Starlink?, how its technology works, what its actual coverage is, how much it costs, what advantages and limitations it has, and whether it can really be a viable alternative to traditional internet, whether you live in the middle of the countryside, at the sea, or in urban areas with access problems. In addition, we will show you how to hire it and what it means to install it in your home or business, all in direct and easy-to-understand language.

What exactly is Starlink?

Starlink is an initiative of SpaceX whose ambitious goal is to offer a Fast, stable, low-latency satellite internet connection almost anywhere in the worldIts main difference from other satellite systems lies in the deployment of thousands of small satellites that orbit at a much lower altitude than traditional ones, forming a network (or constellation) that covers the entire planet.

While conventional geostationary satellites are located about 36.000 km from Earth and generate a very high latency (that annoying lag that makes it impossible to play online games or make decent video calls), Starlink satellites orbit at just 550 km altitude. This allows reduce latency to about 20-40 ms, figures close to the best fiber optic connections.

The idea is simple but powerful: put more than 12.000 satellites into orbit (more than 7.000 have already been launched and are in operation), which communicate with each other and with Earth using optical, laser, and radio frequency technologies. Thus, where a good connection was previously impossible (rural areas, ships, islands, mountains, etc.), navigation is now possible at high speeds.

Elon Musk and SpaceX envision Starlink not only as a business that can connect the more than 3.000 billion people still without internet, but also as a source of funding for their future space plans, including transportation to Mars.

How does Starlink technology work?

The technical principle of Starlink is very different from that of traditional fiber optics or ADSL. The internet signal comes from space, specifically from a network of satellites orbiting the Earth in Ku and Ka bands. These satellites communicate with each other at high speed through laser optical links, allowing them to send and receive data much more efficiently and without relying so heavily on ground stations.

What do I need at home? You must install a Starlink user kit, which includes a flat satellite dish (nicknamed "Dishy McFlatface"), a tripod to mount it in the best view of the sky, a wifi routers and the corresponding cables. The antenna automatically self-tracks to follow the nearest satellite and no manual adjustments are required when moving the satellites.

You connect this kit to the power supply and your local network. The antenna captures the satellite signal, transmits it to the router and you have internetIt is essential to install the antenna in a place free of obstacles (away from trees, chimneys, nearby rooftops, etc.) to avoid signal loss. Although you can't connect from your mobile phone on the street, you can do so at home, at your business, or even in adapted vehicles or boats.

The Starlink network is designed to withstand adverse weather conditions. Expect to find that even if it's raining or windy, you'll rarely lose connection, as is often the case with other satellite technologies. And if you ever experience a brief interruption, it will only last a matter of seconds.

Advantages of Starlink over other connections

The main difference with respect to other connections lies in its speed and latencyTraditional geostationary satellites, being so far from Earth, take a long time for the signal to travel back and forth, resulting in latency of over 600 ms. This makes certain applications, such as online gaming, video calls, or real-time streaming, nearly impossible to use properly.

With Starlink, since the satellites are much closer, latency is drastically reduced and speeds can range, depending on the area and congestion, between 50 and 150 Mbps download. In addition, Starlink is designed to rural, maritime areas and places where neither fiber nor 4G/5G reach, making it the best option for those who live or work in the countryside, islands, boats, mountain regions, or even urban areas with poor infrastructure.

Another big advantage is the global coverage capacity. Wherever you point the antenna and have visibility to the sky, you will have internet. This allows boats, campsites, rural businesses or isolated homes access a connection quality that was unthinkable not so long ago.

How do I check if I can subscribe to Starlink?

Before you decide, you should check if your location is covered. To do this, go to starlink.com and enter your address in the search bar on the main page. The system will automatically suggest the exact address or the nearest location.

Don't know the address or is it a difficult-to-identify place, like a country house? You can use the so-called Google Maps Plus CodeSimply open Google Maps on your phone, mark the location on the map, and copy the plus code that appears under the photo of the location. Then, on the Starlink website, add that code and the country (for example, "JV5X+M23 Morella, Spain"). This will give you the perfect location to find out if Starlink reaches your location.

Once the point is selected, the website will show you the Total budget: the initial equipment price, the monthly fee, and any shipping or installation costs.

Starlink Plans and Pricing

Starlink pricing varies by service type and region, but currently, in Spain and most of Europe, the main plans are as follows:

• Residential plan: Ideal for homes and domestic use. It offers unlimited internet, with a standard monthly cost of €40 and more affordable alternatives from €29 per month. The installation kit costs €349.
• Traveling plan: Designed for travelers and users on the move (motorhomes, trucks, etc.). Portability allows you to connect even when traveling at speeds of over 16 km/h, with prices of €59 monthly or a limited data plan of 50GB to €40 monthly. The base equipment is the same as the residential equipment.
• Boat plan: For sailors, it allows quality internet in maritime zones, with network priority and unlimited data in continental territories. The rates here are much higher, starting from €289 monthly for 50GB and reaching more than €1.158 per month for 1TB of data. The recommended equipment in this case costs about €2.891.

Important: Prices are indicative only and may vary depending on promotions, currency exchange rates, or local conditions. They are updated to the latest available information. It's a good idea to check the website before booking.

Where does Starlink have coverage today?

Starlink is currently rolling out high-speed coverage around the world. It is already operating commercially in United States, Canada, much of Western Europe, Latin America, Australia, Japan, and other countries, with plans to continue expanding. Coverage is constantly updated, so it's worth checking out. the official Starlink map to see if your location is ready. It is estimated that in the next few years it will have total global coverage, except in some territories where regulations or legal issues prevent it.

Please note that in certain countries, whether due to local legislation (such as South Africa) or internal policy, Starlink may not be legally permitted or its availability may be temporarily limited.

Starlink's real-world speed and performance

In testing phases and after commercial deployment, Starlink has achieved download speeds between 50 and 150 Mbps, and latencies of between 20 and 40 ms under normal conditions. These figures may improve as more satellites are launched and the network is optimized, especially in less congested areas.

However, it must be understood that the actual speed depends on location, the weather, the number of connected users, and even certain geographic factors. While there may be minor service outages or slowdowns at times, they are usually short-lived and temporary.

The performance is particularly remarkable in rural or remote areas, where the alternative is the old geostationary satellite or low-quality 3G/4G mobile connections.

How to sign up for and install Starlink?

The hiring process is very simple. You just have to access the website of starlink.com, search for your address (or Plus code if you don't have one), select the plan you're interested in, and place your order. The system will ask for your information, and then you pay for the starter kit and the first monthly payment. Delivery of the equipment typically takes from just a few days to a couple of weeks, depending on stock and location.

Installing Starlink is much easier than it seems. The kit includes clear instructions and all necessary componentsSimply mount the antenna in a high, unobstructed location, connect it to power and your router, and use the official mobile app to adjust or monitor the signal. No advanced technical knowledge or complex installation is required.

In the case of companies, ships or professional solutions, there are options for advanced equipment and specialized advice through authorized distributors.

Do you really need Starlink?

Starlink is a solution designed for those who don't have any other quality alternative. If you already have fiber optic or a good 5G network at a reasonable price, you probably don't need to upgrade. But if you're in areas without terrestrial access, travel a lot, work from unconventional locations, or simply want to ensure internet access in any situation, then it can be your lifeline.

Be clear that, despite the progress, Satellite connections still have some limitations Compared to fiber: slightly higher latency, slightly higher prices, and occasional minor outages. Prices, especially in Latin America and regions where the service is more recent, may be higher than the average for conventional internet.

In areas where ADSL, fiber optic, or cable don't reach or perform poorly, Starlink is the fastest and easiest alternative to install, much more efficient and convenient than any traditional satellite solution.

Challenges, controversies, and the future of Starlink

• Space traffic and collision riskLaunching thousands of satellites increases space debris and makes orbit management difficult. SpaceX has implemented automated systems to move its satellites and avoid collisions, but it remains a global challenge.
• Light pollutionStarlink satellites can reflect sunlight and affect astronomical observations. SpaceX is working to reduce the brightness of its satellites (projects like VisorSat) and to collaborate with the scientific community.
• Legal and privacy aspectsProviding internet without relying on national regulators poses a challenge to sovereignty, security, and privacy. Starlink must comply with the laws of each country and guarantee the protection of user data.

The progress of the technology continues and SpaceX already plans to integrate Starlink into future space projects, such as missions to the Moon and Mars or connectivity in electric and autonomous vehicles.
