What Is Broadband? The 5 Connection Types

Broadband means high-speed internet (25+ Mbps download). Here is how each technology delivers it to your home.

Type	Speed	Latency	Price	Best For
🔵 Fiber	1–8 Gbps	1–4 ms	$50–100/mo	Speed, reliability, and gaming
🟢 Cable	100–1,200 Mbps	10–30 ms	$40–80/mo	Most households — widely available
🟡 DSL	10–100 Mbps	20–45 ms	$30–55/mo	Budget option where fiber/cable is unavailable
🟠 Satellite	25–200 Mbps	300–600 ms	$50–120/mo	Rural areas with no wired options
🟣 5G Home	100–300 Mbps	15–30 ms	$50–60/mo	No-contract alternative in metro areas

Understanding Internet Speeds

Mbps (Megabits per second)

The standard unit for internet speed. 100 Mbps = 100 million bits/sec. Higher is faster.

Download speed

How fast data comes to you — pages, streaming, files. The number providers advertise.

Upload speed

How fast you send data — video calls, photos, cloud backups. Fiber gives symmetric upload; cable gives ~1/10th.

Latency (ping)

Delay in ms between request and response. Under 20 ms is great for gaming. Over 100 ms causes lag.

What Speed Do You Need?

Household	Recommended Speed	Typical Activities
1 person, light use	50–100 Mbps	Email, browsing, social media, HD streaming
2 people, moderate	100–200 Mbps	Two 4K streams, video calls, light gaming
3–4 people, heavy	200–500 Mbps	Multiple 4K streams, gaming, smart home, remote work
5+ people / power users	500 Mbps–1 Gbps	Everything at once: streaming, gaming, downloads, cameras
Home office / creator	500 Mbps–1 Gbps	Large uploads, video conferencing, cloud backups

Understanding Your Internet Bill

The advertised price is never the full price. Here is what shows up on your bill.

Item	Typical Cost	Note
Base price	$40–80/mo	The advertised rate — usually a 12-month promo that increases 40–60% after
Equipment rental	$5–15/mo	Modem and/or router rental. Buy your own to save $60–180/yr
Taxes and fees	$3–8/mo	State/local taxes, regulatory recovery fees, franchise fees
Data overage	$0–50/mo	Charged when you exceed your data cap (usually 1 TB). Not all providers have caps
Installation fee	$0–100 one-time	Often waived with online orders or self-install. Ask before ordering

Internet Jargon Buster

ISP

Internet Service Provider — the company that delivers your internet (AT&T, Spectrum, Frontier, etc.).

Modem

Connects your home to the ISP network. Translates the signal from cable/fiber into data your router can use.

Router

Creates your WiFi network and directs traffic between devices and the modem. Many providers combine modem + router into one gateway.

WiFi / Ethernet

WiFi is wireless (WiFi 6 is current standard). Ethernet is a wired cable — always faster and more stable. Use Ethernet for gaming and work desks.

Bandwidth

Maximum capacity of your connection — like the width of a highway. More bandwidth means more simultaneous devices.

Ping / Latency

Delay in milliseconds between request and response. Under 20 ms is great for gaming. Over 100 ms causes noticeable lag.

Data cap

Monthly limit on data usage (usually 1 TB). Exceeding it triggers overage fees or throttled speeds.

Internet Basics FAQ

What internet speed do I actually need?

For a typical 2–3 person household: 100–300 Mbps handles streaming, gaming, and video calls comfortably. Solo users can get by with 50–100 Mbps. Families of 5+ or remote workers should aim for 500 Mbps to 1 Gbps.

What is the difference between WiFi and internet?

Internet is the connection from your ISP to your home. WiFi is the wireless signal inside your home created by your router. You can have internet without WiFi (wired Ethernet), but you cannot have WiFi without internet service.

Why is my internet slower than what I pay for?

Providers advertise "up to" speeds. Real-world speeds depend on WiFi interference, router age, distance from the router, network congestion, and the number of connected devices. Test with a wired Ethernet connection to get your true speed.

Is fiber internet really worth the extra cost?

Yes, if available at your address. Fiber offers symmetric upload speeds (great for video calls and cloud backups), lower latency (better for gaming), no data caps with most providers, and greater reliability during peak hours. The price gap has narrowed to $10–20/mo vs cable.
