Availability of cable internet, regardless of provider, is shown in the map. Change between a map of the max cable speeds and a map of the number of cable providers using the buttons at the bottom of the map.
Cable internet runs over the same coaxial lines as cable TV, which is why it's available across most cities and suburbs. Downloads typically land between 100 and 2,000 Mbps. Uploads are much slower, and because neighborhoods share bandwidth, speeds can sag during busy evening hours.
When fiber isn't an option, cable is usually the next-best pick.
Availability is reported at the level of hexagons rather than addresses. Not every address is necessarily serviced within a hexagon where a provider reports availability.
The map allows zooming out to view cable internet availability and speeds at the national level. However, the map works best when zoomed in, exploring cable providers and speeds in specific regions.
The availability or speed of service at a single address can dictate the color of the hexagon the address falls within. Accordingly, national-scale views with large hexagons will smooth over local variations in internet availability and speeds.
Cable availability data comes primarily from the FCC's Broadband Data Collection program, representing ISPs' availability as of December 2025 (published May 2026, with FCC revisions through July 2026).
