Knoxville in Tennessee
Knoxville's internet map was redrawn by its utility. In June 2022 fiber reached 59.2%2 of the city's homes and businesses and KUB reported none of them; by June 30, 2026 KUB alone reports fiber at 97.5%, and 68.5%1 of locations have two or more separate fiber networks.
Xfinity, KUB and AT&T on almost every street
Knoxville has 63,047 homes and businesses in the FCC's location list, and three wired providers each report service at nearly all of them. Xfinity reports 99.4%, over cable except for a sliver of fiber (0.1%). KUB reports fiber at 97.5%. AT&T reports 96.2%, but that footprint is mixed: fiber at 69.3% of locations, the rest copper DSL or fixed wireless. WOW! adds a second cable network across 43.8%1 of the city.

Source: FCC, National Broadband Map, data as of June 30, 2026. Share of the area's broadband serviceable locations where the provider reports service as of June 30, 2026. "Only wired option" is the share of locations where it is the single wired provider at 100/20 Mbps. Provider-reported and challengeable; speeds are advertised maximums, not measured; no prices. Satellite providers (HughesNet, Viasat, Starlink) report service at nearly every location and are left out of the table.
All figures are provider reports to the FCC as of June 30, 2026 (revision of November 10, 2026), for the city limits as drawn for the 2020 Census. A provider reports a location as served when it can install a standard connection there within ten business days; anyone can challenge a report on the FCC map. Satellite service from HughesNet, Viasat and Starlink is reported at every location and is left out of the counts of wired choice below.
A utility network built since 2022
At the end of June 2021, Knoxville City Council approved a plan for the Knoxville Utilities Board to lay fiber over ten years and offer broadband as a "fifth utility", according to a September 2021 summary by the University of Tennessee Institute for Public Service. The FCC data trace the result. KUB reported no service in the city in the first National Broadband Map release, as of June 30, 2022. Four years later it reports fiber at 61,4661 locations, more than any other provider reports fiber here.
The citywide fiber share rose by 39.8 percentage points, from 59.2% to 99.0%. KUB's network largely overlaps AT&T's, which reports fiber at 69.3% of locations, so the share with two or more separate fiber networks went from 0.1%2 to 68.5%, the 16th highest among the 343 cities of 100,000 or more. Between December 31, 2025 and June 30, 2026 the fiber share changed by −0.1 percentage points1.

Three fast wired choices at four in five addresses
Counting only wired providers that offer at least 100 Mbps download and 20 Mbps upload, 78.5% of Knoxville's locations have three or more, the 10th highest share among large cities. In June 2022 it was 32.0%. The share with exactly one such provider fell from 26.7%2 to 1.0%. Across Tennessee, 66.4% of locations have two or more wired providers at that speed; in Knoxville it is 98.9%1.
Source: FCC, National Broadband Map, data as of June 30, 2026. Different wired providers (fiber, cable or DSL; FCC provider IDs) reporting 100 Mbps down and 20 Mbps up or more at the same location. Fixed wireless and satellite are not counted.

| United States | 7.8% | 36.6% | 44.6% | 11.1% |
The remaining single-wire locations are few. Xfinity is the only wired 100/20 provider at 0.8% of the city and KUB at 0.2%. 28 locations have no wired provider at 100/20 Mbps, and under the federal BEAD definitions 2 are unserved and 91 underserved. No location in the city is left with satellite as its only option.
Uploads changed more than downloads
Download speeds were already high in 2022: a 1 Gbps download was advertised at 99.7% of locations then and at 100.0% now. The change is in uploads. Wired service of 100 Mbps in both directions, almost all of it over fiber, was reported at 59.2% of locations in June 2022 and at 99.5% now. The FCC's gigabit tier, 1,000 Mbps down with at least 100 up, went from 59.2%2 to 99.5%1.
The fastest advertised download is 2 Gbps or more at 99.5% of locations, against 39.1%2 in 2022. KUB advertises up to 10 Gbps, AT&T up to 5 Gbps on fiber, and Xfinity up to 2 Gbps1 on its small fiber footprint. These are maximum advertised speeds, not measurements, and the FCC data carry no prices; each provider's broadband facts label lists its plans and prices.

Fixed wireless from T-Mobile, Verizon and AT&T
Only 3 companies report licensed fixed wireless in Knoxville, the mobile carriers' home internet service. T-Mobile reports it at 87.7% of locations and offers 100/20 Mbps at 37.7%. Verizon reports 88.5%, with 100/20 at 36.7% and a fastest advertised download of 1 Gbps; after KUB, Verizon's reported footprint grew more than any other provider's since 2022. AT&T reports fixed wireless at a smaller share. Across all three, fixed wireless at 100/20 Mbps reaches 57.9%1 of locations. Capacity on each tower sector is shared, and carriers decide eligibility address by address.
Copper is still in the ground: AT&T's DSL is reported at 69.1% of locations, down 1.2 percentage points1 since 2022, with advertised downloads of up to 100 Mbps.

Knoxville beside Tennessee's other large cities
Fiber reaches nearly every location in three of Tennessee's six largest cities: Chattanooga (100.0%), Clarksville (100.0%) and Knoxville (99.0%). What differs is overlap. Chattanooga has near-complete fiber with two networks at only 6.2% of locations; Knoxville has two at 68.5%, behind only Clarksville (77.9%) in the state's large cities. Nashville (33.5%) and Memphis (13.1%) are well below, and the statewide figure is 22.1%1.

More households subscribe to wired service than in 2019
In the Census Bureau's 2025 American Community Survey, 79.2% of Knoxville households subscribed to cable, fiber or DSL (margin of error ±3.2 percentage points), against 63.4% in 2019 (±2.6 percentage points). The share with no internet subscription fell from 21.6% (±2.4 percentage points5) to 5.8% (±1.9 percentage points4). Both changes are larger than the margins of error. The survey does not say which network households chose, and it counts households over a year while the FCC counts locations on one date.

The figures on this page describe the whole area. Which providers report service at a single home or apartment is shown only on the FCC's own map: search the address at broadbandmap.fcc.gov. If a provider is listed there but cannot actually connect you within ten business days, or the location is missing or misplaced, the map has a button to file a challenge; providers must respond, and corrections flow into later releases. Prices and plans are not part of the FCC data: each provider must show them on its broadband facts label at the point of sale.
