FCC Broadband Map Guide: What It Tells Us About Internet Connectivity

The FCC’s Broadband Map is one of the best tools for researching internet service providers. Whether you’re curious about internet connectivity or trying to figure out what ISPs service your address, the Broadband Map is the best place to start. n fact, it’s so useful that it’s one of the top tools we use to create in-depth reviews and figure out which internet provider is the best in your area.

To ensure the data on the map is current, the FCC updates its database twice a year to keep up with the ever-changing broadband landscape. Especially as fiber providers, 5G home internet and low-orbit satellite internet continue to expand their footprints, keeping an updated database is essential for understanding trends in the broadband industry. The most recent update dropped toward the end of November, making the data current as of June 3, 2024, which is the data we use in our reviews.

But despite the biannual updates, the FCC recognizes its maps and data aren’t without flaws. As the FCC relies on ISP-reported data, occasionally, those providers overcompensate for the census blocks they cover. It can be fairly common for the FCC to list an address as “unserved” or “served” when the opposite is true. To help promote accuracy, users can easily propose challenges to an address, building type, listed providers and available speeds.

Still, if you’re researching internet providers, the FCC Broadband Map is one of the biggest public sources of data on internet availability nationwide and a baseline for mapping the network of internet providers. As of June 3, 2024, fixed wireless internet offerings (which includes 5G internet and excludes satellite internet) increased by 13% — matching the trend of overall high customer satisfaction with the convenience of fixed wireless internet.

Let’s take a closer look at the FCC Broadband Map, how it works, what else it tells us about the state of broadband availability.

Turn to Microsoft’s broadband map for data on internet accessibility

Although the FCC Broadband Map is one of the most important resources for studying broadband connectivity, it’s not the only source of data on internet providers.

Microsoft has its own broadband map, called the Microsoft Digital Equity Data Dashboard. This tool makes use of FCC data as well as data from the US Census Bureau and a few other sources to paint a state-by-state picture of broadband accessibility.

While the FCC’s data focuses on internet provider and connection type availability nationwide, Microsoft’s Digital Equity Dashboard focuses specifically on internet access, so the map has a few more metrics than the FCC’s map — including household data down to specific counties. Unlike the FCC, however, Microsoft limits the map to a state-by-state view. If you’re looking for information specifically on broadband access in your state or county, Microsoft’s map is the place for you. If you’re looking for more general information about what internet is available at your address, the FCC is a more user-friendly way to easily find that information.

How does the FCC Broadband Map work?

The FCC compiles its data with a combination of ISP-submitted data (collected twice a year) and user-submitted corrections.

Fixed wired internet providers report data on a location-by-location basis while fixed wireless providers use something called “propagation modeling” to show a general coverage area. Since fixed wireless providers are subject to so many variables in coverage (from the weather to cell tower capacity), that data may not always accurately reflect the coverage you may get.

Lastly, the FCC also relies on CostQuest, a broadband data consulting firm that uses GIS data to build out the actual map, including serviceable locations or places without a reliable broadband connection. The data presented by CostQuest also undergoes a yearly state-by-state challenge process.

FCC Broadband Map findings: Broadband is available everywhere, with a catch

The latest Broadband Map reveals that 99.98% of US households have a broadband connection — or a minimum of 100Mbps download speed and 20Mbps upload speed. The number of underserved and unserved households decreased to 7.2 million as of June 2024 — down from 8.8 million in December 2023. Although that’s a good change, it doesn’t mean we’ve closed the broadband divide. The latest data also revealed that over a third of Americans can access only one or no internet provider.

Satellite internet, from Hughesnet, Viasat and Starlink, skews the data a bit as each provider is available virtually everywhere in the US and may offer download speeds of 100Mbps or higher (though not by much), in most service areas.

When you take satellite internet out of the equation, as filters on the FCC maps allow you to do, broadband internet is available to only 94% of US households. That includes wired (cable, DSL, fiber) and wireless connections like T-Mobile Home Internet and Verizon 5G Home Internet. Narrowing the scope further to include only cable and fiber service — the best connection types for fast speeds and plan variety — further drops broadband availability to 90%.

Additionally, the percentage of households that can get at least 1,000Mbps download speed and 100Mbps upload speed with cable or fiber is limited to 51%.

Broadband availability by connection type

Cable is the most available connection

After satellite, cable internet is the most widely available connection type with coverage reaching around 82% of US residences. That’s just slightly down from Dec. 31, 2023, potentially due to cable providers adding fiber connections to their networks and moving customers off the cable product.

Comcast’s Xfinity has the greatest cable coverage, available to more than a third of US households, followed by Spectrum at around 29% and Cox at 6%. Lots of smaller, regional cable internet providers make up the remaining coverage. Astound, Mediacom, Optimum and WideOpenWest are notable cable ISPs with national coverage exceeding 1%.

Wireless availability is growing fast

Despite cable internet’s coverage, T-Mobile Home Internet shows the greatest home internet availability of any nonsatellite provider at around 60%. However, it’s worth noting that not all of T-Mobile’s home internet coverage qualifies as broadband — again, that’s speeds of 100Mbps down and 20Mbps up — according to the FCC data. The percentage of households that T-Mobile Home Internet covers with speeds of at least 100Mbps down and 20Mbps up is just 18%.

Notably, nationwide broadband availability from all fixed wireless providers, including T-Mobile along with Verizon 5G Home Internet, US Cellular, Google Fiber’s Webpass, Starry Internet, Rise Broadband and many others, is around 47%. That’s still low compared to cable, but compared to data from just two years ago (December 2022), fixed wireless offerings have increased by 80%.

The surging popularity of fixed wireless internet options may be a good solution for rural broadband, which is sorely lacking in cable and fiber internet.

Fiber coverage is still on the rise

Fiber also saw year-over-year gains, improving from 40% in June 2023 to just under 46% as of June 2024. While the growth is promising, fiber expansion still has plenty of room to keep going, particularly in suburban and rural areas. The FCC data indicates that approximately 49% of households in urban areas are serviceable for fiber internet compared to just 37% of those in non-urban areas.

Other than major cities where fiber internet is most frequently found, your best shot of landing a fiber internet connection is in Rhode Island. Fiber internet is available to more than three-quarters of the state, thanks to major ISPs such as Verizon Fios and Cox. Other states that stood out for exceptionally high fiber coverage include New York (63%), North Dakota (64%) and Connecticut (64%). Alaska had the lowest fiber availability at just over 9% of the state’s households, followed by Arizona (21%) and New Mexico (18%).

What happened to DSL?

DSL internet once rivaled cable internet in availability, but the technology is now largely outdated. As a result, fewer providers are offering DSL internet to new customers and networks are shrinking.

That said, DSL internet may be the only practical home internet option in rural parts of the US. Around 20% of households are serviceable for broadband speeds for speeds of at least 25Mbps down and 3Mbps, which was considered broadband until the FCC raised the definition.

So, what’s available in my area?

The FCC National Broadband Map lets you narrow results to an area — state, county, census place, tribal area or metropolitan statistical area — or a specific location, such as your current address or an address you may be moving to.

Searching by address returns the most detailed results. After entering an address, you’ll get an alphabetized list of available providers, the connection type they use and the max speeds they offer. Keep in mind that the max speeds may not be the only speeds an ISP offers. For example, Comporium and Spectrum offer download speeds up to 1,000Mbps at my address, but lower speed tiers of 300 and 500Mbps are also available.

On the flip side, while some ISPs may advertise speeds up to 150Mbps or 220Mbps down, there’s no guarantee you’ll actually see those speeds with daily use due to network congestion, throttling or Wi-Fi issues.

Report any inaccuracies to the FCC

FCC broadband maps and data have certainly improved in recent years, but it’s far from being completely accurate. If you notice incorrect information for an address, whether that involves property details or the providers that serve it, don’t hesitate to report it to the FCC.

It’s easy to submit a challenge request, you just have to create an account with the FCC Broadband Map site first.

You can use the Location Challenge link to report any incorrect property details, such as the listed address, building type and number of units. The Availability Challenge link allows you to send feedback or challenge the provider details for the address, including the need to add missing providers. Your submission will require name, address and contact information along with the reason for your challenge and any documentation you have supporting your claim.

Submitting a challenge form should only take a few minutes. Doing so helps ensure the FCC data accurately represents your address, which could affect future funding or expansion efforts for ISPs in your area.
