Satellite Internet access
Satellite Internet doesn’t replace broadband—it patches its geography with physics, not policy.
Satellite Internet access is a point-to-multipoint radio system using geostationary, MEO, or LEO satellites to deliver IP traffic where terrestrial infrastructure fails. It works via Ku/Ka-band microwave links between dishes and satellites, with throughput and latency dictated by orbit height and spectral efficiency. It delivers usable broadband to isolated users—but introduces new failure modes (weather, obstruction, orbital congestion) and does not compete on cost, latency, or reliability with terrestrial alternatives where they exist.
Ku-band geostationary service remains the dominant delivery method—and the Ka-band opening enabled the capacity leap.

2003–2004: The Capacity Inflection
The first consumer Internet-ready satellite launched in September 2003; Anik F2 in 2004 defined the high-throughput class.

Latency Is the Design Constraint
LEO constellations emerged after 2014 specifically to fix geostationary latency—not to increase speed or coverage alone.

Orbit First, Internet Later
Syncom3 (1963) proved geostationary orbit was possible—but it carried no Internet protocol stack, no modems, no standards.

What it is and the problem it solves
It is a wireless wide-area network that beams Internet access from space to fixed ground terminals. It solves the problem of connecting users beyond the reach of terrestrial infrastructure—especially in rural, maritime, or airborne settings.
How it works
Satellite Internet access uses microwave radio communication between satellites and ground stations. It operates in the Ku and Ka frequency bands. Geostationary satellites are typical for consumer service; newer constellations use medium or low Earth orbit to reduce latency.
What works
Ku-band geostationary service delivers up to 506 Mbit/s downstream to individual users. High-throughput satellites like Anik F2 (2004) increased capacity. LEO constellations like Starlink and OneWeb reduce latency by shortening the signal path.
What does not
It does not deliver consistent low latency from geostationary orbit. It does not eliminate dependency on ground infrastructure: every user requires a line-of-sight dish, modem, and often a terrestrial backhaul link for the gateway station. It does not scale cost-effectively for dense urban users.
What it changes
It changes where fixed broadband can be deployed—not by replacing terrestrial networks, but by bypassing them entirely in remote or underserved regions. It shifts spectrum allocation pressure toward Ka-band licensing and intensifies orbital slot competition.
Is it worth your time
Yes—if you need connectivity where fibre or mobile broadband is unavailable, and can tolerate latency spikes, weather-related outages, and strict data caps. No—if your work depends on real-time interaction, consistent throughput, or predictable uptime.
