Constructing out fiber optic community over hundreds of miles to supply web to tens of millions of individuals is a tough, time-consuming, and costly process. What in case you might reduce out the bodily connections fully and solely use wi-fi? That’s precisely what Starlink goals to do.
What’s Starlink?
Starlink is a community of satellites (referred to as a constellation) that orbit the Earth that gives wi-fi web entry to houses, automobiles, RVs, and boats. Some airplanes are even outfitted with Starlink now.
How Does Starlink Work?
Starlink depends on the identical expertise that enables Wi-Fi, Bluetooth, and FM Radio to function: radio waves.
Every satellite tv for pc is able to sending and receiving data to and from relays on Earth, which allows it to hook up with the web.
A few of relays that the Starlink community makes use of are giant, industrial floor stations referred to as gateways. These gateways let Starlink satellites join on to the high-speed, fiber optic connections that make up the spine of the web on Earth.
The opposite relays are a lot smaller. Some are stationary items designed to be connected to your property or a ship, whereas others, like Starlink Mini, are sufficiently small to suit inside a laptop computer bag.
This community of satellites and relays now permit anybody with the proper {hardware} to obtain web service nearly wherever on the planet, and the community is simply getting bigger as time goes on.
The satellites themselves are additionally getting bigger and extra advanced. Starlink satellites characteristic lasers that permit the satellites to instantly join to one another, doubtlessly permitting them to chop out the Earth as a intermediary and bettering efficiency.
Starlink V2, which is ready to start a full rollout as soon as SpaceX’s Starship is working reliably, will probably be even bigger and extra refined.
What Makes Starlink Completely different from Different Satellite tv for pc Web?
There are three most important variations between Starlink and older satellite tv for pc web providers.
They Orbit Very Shut
One of the hanging variations between Starlink and older satellite tv for pc web providers is the orbital distance. At present, Starlink satellites orbit about 350 miles from the floor of the planet, an space referred to as “low Earth orbit,” or LEO. Most older satellite tv for pc web providers operated in geostationary orbit, which is a few 22,000 miles away, as a substitute. However why the distinction?
Geostationary orbits provide some advantages. The satellite tv for pc is at all times on the identical level within the sky, which makes connecting to it simple: simply level your antenna and also you’re good. The opposite massive one is visibility. When the satellite tv for pc is so far-off, it’s seen from an enormous quantity of the Earth’s floor. That signifies that you don’t want many satellites to supply protection for a lot of individuals.
Associated
Interested by how satellite tv for pc web works? It is truly extra sophisticated than you would possibly suppose.
The most important downside is the latency.
Whereas radio waves do journey on the velocity of sunshine (some 670 million miles per hour), 20,000 miles continues to be far sufficient to introduce latency—practically 500 milliseconds, or half a second. Should you’re simply searching the web or watching Netflix, it most likely gained’t matter to you, nevertheless it makes on-line gaming tough or inconceivable. Any interactive service on the web will probably be noticeably laggy with a ping that prime.
I Don’t Let Slow Rural Internet Stop Me From Playing Games
Being in the course of nowhere does not imply being disconnected.
As a result of Starlink satellites are solely a tiny fraction of the space, the latency is decrease, and actions like aggressive gaming are viable.
The Amount of Satellites
The massive trade-off with distance is visibility. The antenna you set in your house can’t “see” the satellite tv for pc, then you possibly can’t type a connection. When the satellites are as near Earth because the Starlink satellites are (solely about 350 miles), visibility is poor, and also you want extra of them. Should you’re planning on offering a viable international web service, you additionally want extraordinary quantities of bandwidth, which additionally requires a number of satellites.
You Can Use Starlink with a Cellphone
Satellite tv for pc telephones have been a factor for many years, however they have been giant, specialised units.
Starlink permits cellphones to attach on to the satellites in orbit for texting and calling. To date, the rollout has been restricted, however because the {hardware} turns into optimized on each the satellites and in cellphones, and because the Starlink community grows, we’re certain to see extra carriers and telephones assist the characteristic.

ET is not the one one who will get to telephone residence.
How Many Starlink Satellites Are In Orbit?
As a result of Starlink orbits so near the Earth and the demand on the system from the variety of individuals utilizing it, you want hundreds of satellites. As of April 2025, there are greater than 7,000 Starlink satellites in orbit, and there are plans to launch at the very least 5,000 extra.
SpaceX has expressed curiosity in increasing the community even additional, to greater than 40,000 satellites in whole, pending regulatory approval.
What Occurs to Starlink Satellites When They Attain Finish of Life?
No expertise lasts endlessly, and the Starlink satellites are not any exception. As a result of the satellites are so near the planet they usually have restricted gas, drag from the higher limits of the environment regularly reduces their velocity till they renter the Earth’s environment and expend.
Whereas outdated Starlink satellites expend, SpaceX plans to repeatedly launch new, upgraded satellites to interchange them.
Scientists don’t but know what affect (if any) so many satellites burning up within the environment can have on the planet. Nonetheless, the satellites are composed of supplies not normally discovered within the environment, so we’re firmly in uncharted territory.
