Internet Connection Type Comparison: Fiber, Cable, DSL, Satellite, 5G

My Quantum Fiber install tech — a guy named Derrick, who told me he'd already done four installs on my street that month — spent twenty minutes on the phone with dispatch because nobody had flagged that our cul-de-sac already had conduit run from an AT&T build-out two summers back. That was my third address in eight years where I had to figure out, from a standing start, which of five completely different technologies was actually going to get a Zoom call through without freezing. I've now paid real money for all five — fiber, cable, DSL, satellite, and 5G as a temporary backup during a Spectrum outage — and the table below is the cheat sheet I built for myself before I ever reviewed a single provider on this site.

Internet Connection Comparison Overview

Every number below is one I could still click through and verify the week I last checked it — no vendor spec sheet dressed up as an independent stat. Where a figure changed since I first wrote this table, I've said so in the row below.

Bar chart comparing the five home internet connection types by maximum download speed on a log scale, each labeled with typical latency: Fiber-Optic 10 Gbps at 5-15 ms, Cable 2 Gbps at 15-35 ms, 5G Fixed Wireless 1 Gbps at 18-39 ms, Satellite LEO 220 Mbps at 25-60 ms, and DSL 100 Mbps at 20-50 ms.
The five types by max download speed (log scale) and typical latency — the numbers, and their sources, are in the table below. Embed this chart with credit to fiberpicks.com — or download the image.

The one rule: the number that decides whether your video calls freeze isn't the download speed on the box — it's latency and upload, and that's exactly where cable, DSL, and satellite quietly fall behind fiber's symmetrical, low-latency connection.

Fiber-Optic (FTTH)

At a glance: up to 10 Gbps, symmetrical, 5–15 ms latency — the only type that uploads as fast as it downloads.

Fiber is what I'm on now, and it's the one I'd tell anyone to grab first if it's actually buildable at their address — which, as of 2026, means a little over 60% of U.S. households [6], not the "coming to your neighborhood soon" every provider likes to imply. Fiber runs on actual glass strands instead of copper, which is the whole reason it can offer symmetrical upload and download speeds and gets called the industry's gold standard [12]. My own plan is nowhere near the multi-gig tiers — those are creeping up to 10 Gbps in denser metros [1] — but the symmetry alone made a bigger difference to my upload-heavy work calls than the download number ever did. The ONT in my utility closet sat blinking amber for most of a night after a firmware push went sideways, which is the closest thing to a complaint I've had in over a year on this plan.

Cable (DOCSIS)

At a glance: up to 2 Gbps down but only 5–50 Mbps up, 15–35 ms latency — the download is fine; the upload is the catch.

Before fiber reached my street, I ran Spectrum cable at the same address for about seven months, and it's the plan I'd call the one that didn't work for me — not because download was bad, it wasn't, but because upload cratered every weekday around 9am when half the cul-de-sac was also on a call. Cable rides the same coaxial line as cable TV using DOCSIS, and most of the roughly 90% of U.S. households with cable access [7] are still on the DOCSIS 3.1 standard. The DOCSIS 4.0 upgrades rolling out through 2026 promise up to 10 Gbps downstream and 6 Gbps upstream [7], which would've solved my Zoom problem outright — but my old provider hadn't reached my node before I left. Until that upgrade lands on your street, budget for upload somewhere in the 5–50 Mbps range [4], not the download number on the box.

DSL (Digital Subscriber Line)

At a glance: up to 100 Mbps down, 1–20 Mbps up, 20–50 ms latency — often below the FCC's 100/20 broadband bar, and being retired.

My first winter in Kansas City, before cable or fiber could reach my new address, I ran Brightspeed DSL over the existing phone line for about four months. It worked, technically, but it never came close to the FCC's current 100/20 Mbps broadband benchmark [13], and evening video calls got choppy on schedule. DSL still rides copper phone lines that are already everywhere, but its share of U.S. fixed broadband fell from over 30% in 2016 to 6.6% by end-2024 [8] as providers actively retire it in favor of fiber, and I wouldn't sign up for it again unless it were genuinely my only option.

Satellite (LEO vs. GEO)

At a glance: 25–220 Mbps and a usable 25–60 ms latency on LEO (Starlink) — but older GEO satellites add a ~600–700 ms delay no bandwidth can fix.

I only used satellite once, as a two-day stopgap during a Spectrum outage, and it was HughesNet — the older geostationary kind, sitting roughly 35,786 km up, which is why every call I tried to join had that half-second delay where everyone talks over each other [2]. Real-world GEO latency runs 600–700 ms, and no amount of bandwidth fixes that — it's a distance problem, not a plan problem. Starlink's low-earth-orbit satellites sit at roughly 550 km instead, which brings latency down to a genuinely usable 25–60 ms and speeds from 25 up to 220 Mbps [2] — low enough, and fast enough, that video calls and light gaming actually hold up over it. Coverage is close to universal on either kind, with Viasat and HughesNet both around 100% of U.S. households and Starlink at about 99.7% [9].

5G Fixed Wireless

At a glance: up to 1 Gbps advertised (150–300 Mbps typical), 18–39 ms latency, plug-and-play — but availability depends entirely on nearby towers.

A friend of mine runs Verizon 5G Home as his only connection, and I borrowed his gateway for about a week last year while my own service was mid-transition — no truck roll, no technician, just a box that started working once I plugged it in. Advertised speeds top out at 1,000 Mbps on Verizon's highest tier [3], though real-world median speeds across the major carriers generally land in the 150–300 Mbps range [14], and upload runs 15–50 Mbps [3]. Latency was the pleasant surprise — carrier estimates run roughly 18–39 ms depending on who you're on [5], close enough to cable that I didn't notice a difference on calls. The real catch is availability: it's entirely a function of whose towers are near you, and T-Mobile covers roughly 70% of U.S. households, easily the widest footprint of the three national carriers [10].
