Fiber, cable and 5G home internet are not the same thing

Fiber

Light down a glass line that runs to the building. The thing that sets it apart isn't the download number — it's that upload is usually close to download. If you work from home, back up large files, or have several people on video calls at once, that symmetry is what you actually feel. It's also the least affected by what your neighbors are doing.

The catch is reach. Fiber has to be physically built to an address. Two houses on the same street can get different answers, and a building two blocks away can have it when yours doesn't.

Cable

The same coax that carried cable TV. Download speeds are strong and it's available at far more addresses than fiber. Upload is the trade-off — on most cable plans it's a small fraction of download, which is why a video call can look fine to you and choppy to everyone else.

Cable is a shared line through the neighborhood, so performance can dip at the times everyone is home.

5G home internet

A receiver in your house pulls a signal from a nearby cell tower. No line to the building, so install is usually just plugging it in, and it reaches places wired service hasn't.

Because it's wireless, performance depends on distance from the tower, what's between you and it, and how busy that tower is. Two apartments in the same complex can get noticeably different results. It's worth testing in the actual room where you'd put it.

Which one is right

There isn't a universal answer, and anyone who gives you one without asking about your address hasn't checked anything. What usually decides it:

• What's actually built to your address — this rules out most of the debate before it starts.
• How much you upload — working from home, streaming, large files, security cameras.
• How many people are on it at once.
• Whether your building is wired for one provider only — common in apartments, and sometimes bulk-billed so you can't change it.

Why address-level matters

Coverage maps are drawn at the neighborhood or ZIP level and are routinely wrong at a specific house. The only reliable answer comes from checking the address itself.

That's the part I do. Send me your address and I'll check what's actually there, then call you and go through it.
