Internet in Clarksville, Tennessee

Three wires reach almost every home

Clarksville's provider list is short, and three names on it matter for wired service. As of June 30, 2026, CDE Lightband reports fiber at 100.0% of the city's 56,741 homes and businesses, Spectrum reports service at 94.7% and AT&T at 96.4%¹. The remaining wired providers each report fewer than one location in a hundred.

A provider "reports service" when it tells the FCC it can install it within ten business days at a standard location; anyone can challenge a listing on the FCC map. The table counts locations inside the city limits as drawn for the 2020 Census, in the FCC release revised November 10, 2026.

Fiber everywhere, from the electric utility

CDE Lightband is the Clarksville Department of Electricity, which supplies both electricity and broadband in the city. Its fiber covers every location the FCC counts here, so fiber is available at 100.0% of Clarksville, tied for the highest among large cities, against 80.5% across Tennessee and 62.6%¹ nationally. The share was already 95.5%² in June 2022, so the map shows no fiber growth here since then: there was nowhere left to grow.

CDE Lightband advertises downloads of up to 1 Gbps. On its own it is the only wired provider at 100/20 Mbps for 1.7% of locations, 968¹ homes and businesses in all.

Clarksville and cities of similar size

Fiber at every location ties Clarksville for the top of the large-city fiber ranking. The table sets it beside the cities closest to it in population, all from the same FCC release.

Symmetrical speeds are standard

Because every location has fiber, every location also has symmetrical service: wired 100/100 Mbps is reported at 100.0% of locations and the 1,000/100 gigabit tier at 100.0%, compared with 87.5% statewide and 72.3% in the US. The top advertised tier has moved up: the fastest download offered is 2 Gbps or more at 64.1% of locations, against 26.2%² in June 2022, with AT&T advertising up to 5 Gbps. At the other 35.9% it is at least 940 Mbps but under 2 Gbps. The chart adds Chattanooga, the other large Tennessee city where fiber is reported at 100.0%¹ of locations. These are advertised maximums, not measurements.

The change since 2022: a second fiber network

The movement in Clarksville is in the second and third wire. The share of locations where two or more different companies report fiber rose from 54.7%² in June 2022 to 77.9%, the 8th highest share among large cities. AT&T is the main second network: it reports fiber at 77.2% of locations, and Spectrum, otherwise a cable provider here, reports fiber at 11.8%¹.

Choice rose with it. Locations with three or more wired providers at 100/20 Mbps went from 51.7%² to 74.7% (+23.0 percentage points). Over the same period the share reached by cable fell 7.1 percentage points to 83.6%, and DSL fell 6.7 percentage points to 58.3%¹.

Chattanooga: the same fiber reach, less overlap

One other large Tennessee city matches Clarksville on fiber reach. In Chattanooga, EPB reports fiber at 100.0% of locations, but only 6.2% have a second fiber company, and 9.1% have three or more wired choices at 100/20 Mbps. Clarksville's figures are 77.9% and 74.7%. Statewide, 22.1% of locations have two or more fiber networks and 66.4%¹ have at least two wired choices at 100/20.

5G home internet and copper

Two mobile carriers report 5G or LTE home internet across most of the city, and AT&T reports fixed wireless at some locations. Verizon reports it at 91.5% of locations, with 100/20 Mbps at 33.1%; T-Mobile reports 74.5%, with 100/20 at 17.6%. Carriers limit sign-ups by address because a tower sector's capacity is shared, so these shares mark where service is reported, not where everyone could join at once. AT&T's DSL lines still reach 58.3%¹ of locations, with advertised downloads of up to 100 Mbps.

Subscriptions: fiber at the door, a phone plan inside

Availability and subscription are different things. In the Census Bureau's 2025 survey, 97.9% of Clarksville households had a broadband subscription of some kind (margin of error ±1.1 percentage points), and 78.9% subscribed to cable, fiber or DSL (±3.9 percentage points). 16.5% relied only on a cellular data plan (±3.9 percentage points), compared with 12.5%⁴ across Tennessee; the city's margin of error is wide enough that the gap may not be real. The survey counts households over a year and the FCC counts locations on one date, so the two sets of figures sit side by side rather than add up.
