If you’ve been researching internet options in rural South Texas, you’ve probably run into the term “Air Fiber.” It sounds like marketing language — and in some ways it is — but there’s real technology behind it that makes a meaningful difference for rural households. This guide breaks down exactly what Air Fiber is, how it works, how it compares to satellite, and what you can expect if you decide to get it installed.

What Air Fiber Actually Is

Air Fiber is a brand term for fixed wireless internet — a technology that’s been around for decades but has improved dramatically in the last several years. The core idea is simple: instead of running a fiber or cable line to your house (expensive, slow to build, often impossible in rural areas), a provider installs a small antenna on your home that communicates wirelessly with a transmission tower a few miles away.

That tower is connected to the broader internet via high-capacity fiber backhaul. Your antenna talks to the tower, the tower talks to the internet, and the whole chain operates faster than most people expect from a wireless connection.

South Texas Internet uses this technology across our coverage area in Medina, Atascosa, Frio, and surrounding counties. When we say Air Fiber, we mean fixed wireless broadband delivered from our local tower network — not a satellite, not a cellular hotspot, not DSL running over aging copper lines.

How the Installation Works

The installation process is straightforward and typically completed within one business day of your order being confirmed.

Our technician will assess your property to identify the best location for the antenna — usually the roofline, a chimney, or a pole mount in the yard. Line of sight to our nearest tower is important, so the tech will determine the optimal placement to maximize signal quality.

The antenna itself is small — roughly the size of a large book — and mounts cleanly to the structure. A cable runs from the antenna into your home to a router, which distributes your WiFi signal throughout the house. The technician handles the full installation, tests your speeds before leaving, and walks you through the setup.

There’s no equipment purchase required. The hardware is included in your service, and if anything fails, we replace it. No surprise hardware bills.

How Air Fiber Compares to Satellite

The most common comparison we hear is Air Fiber vs. Starlink. Both are wireless. Both reach rural areas that cable doesn’t. But the way they work is fundamentally different, and those differences affect your daily experience.

Starlink’s signal travels from your dish to a satellite in low Earth orbit — roughly 340 miles up — and back down to a ground station, then back to the satellite, then back to your dish. That round trip happens in milliseconds, but it adds latency that ground-based systems simply don’t have. Starlink’s latency typically runs 20–60ms. Ours runs under 50ms and often under 30ms.

For streaming and general browsing, that difference is hard to notice. For video calls, online gaming, remote desktop connections, and VoIP phone systems, it matters every day.

Beyond latency, satellite capacity is shared. If hundreds of Starlink users in your area are all streaming at 7pm, everyone’s speeds drop. Fixed wireless from local towers has a more predictable performance profile because your connection isn’t competing with a regional satellite cell.

There’s also the weather factor. South Texas gets serious storms. Heavy rain, thick cloud cover, and the kind of fast-moving thunderstorms common from spring through fall can affect satellite signal quality in ways that ground-based fixed wireless handles differently. Our towers are built for Texas conditions.

What Speeds to Expect

Our standard plan — Velocity 400 — delivers 400 Mbps download and 25 Mbps upload. For most rural South Texas households, that’s more than enough for everything running simultaneously: streaming on multiple TVs, video calls for remote work, kids gaming online, and a smart home full of connected devices.

The 25 Mbps upload speed is worth highlighting specifically. Most internet advertising focuses on download speed because it’s a bigger number. But upload speed is what determines how well your video calls look to the other person, how fast you can back up files to the cloud, and how smoothly your remote desktop connection runs. Satellite providers in particular tend to have weak upload — Starlink averages 5–15 Mbps up in South Texas. Our 25 Mbps up is a meaningful improvement for anyone who works from home.

Who Air Fiber Is and Isn’t Right For

Air Fiber works best for addresses with a clear line of sight to one of our towers. Heavily wooded properties, deep valleys, or locations far from any tower may experience reduced performance or may not be serviceable at all. The best way to find out is to call us — we’ll check your specific address before you make any commitment.

Air Fiber is an excellent fit for: households replacing satellite service, remote workers who need reliable upload speed, families with multiple simultaneous users, and anyone tired of DSL speeds on aging copper lines.

It’s worth a conversation if you’re on a rural route, a ranch property, or anywhere outside the reach of cable or fiber — which describes most of our service area.
