The Last Mile of the Internet Is Moving to Orbit: Starlink Gen2 and Amazon Leo, Explained

The fight over the future of the last mile of the internet moved decisively into orbit this week. In the space of a few days, SpaceX secured federal approval to build a 15,000-satellite next-generation mobile constellation and positioned itself to become a full-fledged American wireless carrier, while Amazon hit a factory milestone that puts its long-delayed satellite internet service on track to launch before the end of the year. Two companies are now racing to own the part of the internet that comes after the cable, the fiber, and the cell tower.

This matters beyond a corporate rivalry. For the first time in the history of the internet, a meaningful share of everyday connectivity may bypass terrestrial networks entirely. Understanding how these systems work, and what changes when they arrive, is understanding where the internet itself is going.

The SpaceX regulatory breakthrough

The biggest development of the week came from the Federal Communications Commission. The agency approved the application for Starlink Mobile Gen2, a constellation of up to 15,000 satellites optimized for 2GHz spectrum and designed to deliver cellular service directly to ordinary phones around the world.

The FCC also granted SpaceX a waiver that lets the company offer wireless service without a spectrum leasing agreement with a terrestrial carrier, a significant step toward becoming a genuine mobile carrier in its own right rather than a partner riding on another network. SpaceX says the Gen2 satellites will deliver more than 100 times the bandwidth of the current generation, which provides basic direct-to-cell service over roughly 650 satellites at about 5 megabits per second.

Separately, SpaceX announced it is acquiring a low-band spectrum portfolio in the 800MHz range, closing what it called one of the remaining technical gaps in its carrier ambitions. The physics are straightforward: 2GHz mid-band spectrum delivers high-capacity mobile broadband, while 800MHz low-band signals penetrate walls and reach indoors. Combine both with what SpaceX describes as an advanced terrestrial deployment, and the company can promise a single network that works indoors, outdoors, and in cellular dead zones.

For the first time in the history of the internet, a meaningful share of everyday connectivity may bypass terrestrial networks entirely.

The incumbents noticed. After SpaceX announced its carrier ambitions, shares of AT&T, Verizon, and T-Mobile all fell, with Verizon logging its worst one-day decline since 2002, according to market reports. The irony is sharp: the existing T-Mobile satellite feature already runs on Starlink, but T-Mobile recently removed SpaceX branding after finalizing a joint satellite venture with AT&T and Verizon. The three terrestrial giants are teaming up precisely because the threat from orbit is now real.

How the Amazon factory closed the gap

While SpaceX consolidates its lead, Amazon finally solved its production problem. The company announced it has manufactured its 1,000th satellite for Amazon Leo, the broadband constellation formerly known as Project Kuiper, at its 170,000-square-foot factory in Kirkland, Washington. The first 27 satellites took six months to build; the factory now produces 27 per week, shipping finished spacecraft to Florida every two to three days for launch.

Chris Weber, the Amazon Leo vice president of business, said the company plans to begin initial commercial service before the end of 2026. That ambition comes with a caveat: only 396 of the 1,000 built satellites are actually in orbit, and the first-generation constellation is supposed to total 3,232. A Vulcan rocket carrying 40 Leo satellites is expected later in October, while an Ariane 6 launch carrying 36 more is paused over a turbo pump glitch.

The launch bottleneck has already cost Amazon. The company missed an FCC deadline to have half its planned network in orbit by July 2026, partly because a rocket exploded on the launchpad in May. The FCC granted an extension but imposed a penalty: satellites launched after the deadline temporarily lose priority access to spectrum. SpaceX, which opposed the Amazon extension request and called it gamesmanship, will be watching to see whether regulators enforce the spirit of that decision.

Still, Amazon is promising bold specifications: download speeds of up to 1 gigabit per second, roughly double the top Starlink home plan, and airlines Delta and JetBlue have already signed up for Leo-powered in-flight WiFi.

How a satellite becomes your internet provider

The internet, at its core, is a network of networks. Terrestrial internet works because your home router talks to a local exchange, which hands traffic to ever-larger backbone networks. Satellite broadband rewrites only the first hop: instead of a cable or fiber line, your dish or phone talks to a satellite passing overhead at roughly 500 kilometers altitude, moving at 7.5 kilometers per second.

That satellite relays your traffic down to a ground station, also called a gateway, where it joins the ordinary terrestrial internet. From there, everything works exactly as it always has: DNS resolves the address, BGP routes your packets across backbone networks, and content delivery networks cache data at the edge. The satellite is simply the on-ramp.

The direct-to-cell version goes further. The current Starlink mobile service uses about 5MHz of bandwidth and handles basic messaging and apps, a service already live in markets such as Bangladesh. The Gen2 satellites, using EchoStar spectrum, will have at least 65MHz available, which SpaceX expects to translate into around 150Mbps per user, fast enough for genuine mobile broadband without a terrestrial tower in sight.

Why the race matters, and what could go wrong

The promise is real: reliable broadband for rural communities, ships at sea, disaster zones, and the billions of people with no affordable terrestrial option. Amazon is already asking regulators in India to count satellite links as backhaul for public WiFi networks and rural broadband programs, while Starlink satellite-to-mobile services have launched in Bangladesh and Lesotho this month.

But orbit is a shared resource, and it is getting crowded. Spectrum is finite. Debris risk grows with every launch. And both business models assume regulators will keep approving bigger constellations indefinitely. The spectrum penalty the FCC imposed on Amazon shows that the regulatory runway is not unlimited.

There is also the question of who owns the future. The internet was designed as a decentralized network of networks, resilient precisely because no single operator controlled it. Two American companies controlling the last mile in the sky is not decentralization; it is a new kind of centralization, just higher up. For the first time, the map of who can reach the internet may be drawn by the launch cadence of two corporations.

The week that was supposed to belong to factories and regulators turned out to be about architecture. The internet is gaining a second physical layer, floating 500 kilometers overhead, and the race to build it just shifted into high gear.
