Sunnyvale in California
In Sunnyvale, AT&T's network is half fiber and half copper.

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.
A share in this table counts the locations where a company tells the FCC it can start service within ten business days of a request. A location is a place where service can be installed: a house, a small business, or an apartment building counted once. That is largely why the FCC lists 34,4641 locations while the Census Bureau estimates 59,077 households (margin of error ±2,2252). The reports can be challenged, and a single address can be checked on the FCC map.
AT&T's network: half fiber, half copper
AT&T reports some service at 87.5% of Sunnyvale's locations, but what it offers depends on the location. Its fiber reaches 48.9% of locations. DSL over copper telephone lines, which in Sunnyvale is almost entirely AT&T's, is reported at 50.9%. The two footprints are about the same size, and some locations are reported with both. AT&T offers 100/20 Mbps at 56.5%1, a little more than its fiber share.
Fiber has grown. Fiber from any provider reached 35.9% of locations in June 2022 and reaches 49.7% now, a rise of 13.8 percentage points. The DSL share fell faster, by 7.7 percentage points from 58.6%. Statewide DSL went from 58.9%3 to 43.7% over the same four years. Since December 2025 neither share has moved much: fiber is up 1.0 percentage points and DSL down 0.1 percentage points1.

The FCC's count of locations is updated with each release, so shares are compared rather than counts.

The data show where copper is still reported, not why the DSL share fell by more than the fiber share rose. 4 companies report fiber somewhere in the city, against 23 in June 2022, but apart from AT&T they reach small pieces of it: Xfinity reports fiber at 0.8% of locations and Sail Internet at 0.7%1.
Where Sunnyvale sits among its neighbors
Fiber at 49.7% puts Sunnyvale just above California's 47.8% and below the US share of 62.6%; among the 343 US cities of 100,000 or more it is 84th lowest. In Santa Clara County the neighbors are similar: Santa Clara is at 51.7% and San Jose at 43.9%. Further up the Bay the range widens: Fremont is at 38.2% and San Mateo at 88.3%1.

Copper has retreated slowly in Sunnyvale and next door: Sunnyvale's DSL share fell by 7.7 percentage points since June 2022. Santa Clara's went from 85.0% to 76.4%, San Jose's from 62.1%3 to 58.1%1.
One wire or two, depending on the fiber
Wired service of at least 100/20 Mbps is reported at 98.6% of locations, tied for 167th lowest among large cities because nearly every city is close to the top. Choice is the real difference. Two or more wired providers at that speed are available at 55.2% of locations, close to the fiber share, since AT&T fiber is the second wire almost everywhere it runs. At 43.3% there is only one, and Xfinity is that one at 43.1%. California's figures are 49.9% with two or more and 43.2%1 with one.
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.

| California | 6.9% | 43.2% | 43.4% | 6.5% |
| United States | 7.8% | 36.6% | 44.6% | 11.1% |
In June 2022, 54.5%3 of locations had a single wired provider at 100/20 Mbps; that share fell by 11.1 percentage points, while the share with two or more rose by 11.3 percentage points. Three or more wired choices remain rare, at 0.8%1.
Upload speeds rose too. Gigabit service with uploads of at least 100 Mbps (the FCC's 1,000/100 tier) is advertised at 76.8% of locations, more than the share with fiber, up from 35.9%3 in June 2022. The fastest advertised download is 2 Gbps or more at 75.5%. Xfinity advertises up to 2 Gbps and AT&T up to 5 Gbps1. These are maximums providers advertise and report to the FCC, not measured speeds.
A licensed radio network across the whole city
Fixed wireless sends service by radio from a provider's antenna to a receiver on the building. In Sunnyvale the widest network of this kind is not a mobile carrier. Etheric Networks reports licensed fixed wireless at 94.0% of locations and 100/20 Mbps at all of them, with a top advertised download of 250 Mbps. It reports service in 1 state only, at 941,0001 California locations.

Counting all providers, licensed fixed wireless at 100/20 Mbps or more is reported at 96.1% of Sunnyvale's locations, 13th highest among large cities, against 56.1% statewide. In June 2022 the city's figure was 12.1%3. Verizon reports home internet at 74.6% of locations and T-Mobile at 65.3%, with 100/20 Mbps at 27.8% and 32.7%1 respectively.
Unlicensed networks, which use shared radio bands, moved the other way. They were reported at 93.5%3 of locations in June 2022 and 84.2%4 in December 2025, and at 48.8% in June 2026. The largest now are Tekify Fiber & Wireless (25.5%), which reported no Sunnyvale locations in June 2022, Ridge Wireless (24.2%) and Sail Internet (15.2%1).
For a small group the radio network is the only fast option. At 489 locations (1.4%) no wired provider reports 100/20 Mbps; at 321 of them (0.9% of the city, tied for 89th highest among large cities) fixed wireless is the only way to reach that speed. Only 71 locations have satellite alone. A radio provider's map shows where it says it can serve; everyone on an antenna sector shares its capacity.

What Sunnyvale households subscribe to
The Census Bureau's American Community Survey asks households what they pay for. In the 2025 survey, 96.8% of Sunnyvale households had a broadband subscription (margin of error ±1.3 percentage points), against 95.6% across California, and 85.8% had cable, fiber or DSL (margin of error ±2.7 percentage points2).
9.5% relied only on a cellular data plan (margin of error ±2.5 percentage points) and 2.9% had no internet subscription (margin of error ±1.2 percentage points2). The 2019 survey put those at 6.0% and 5.2%5; the margins overlap, so the survey cannot show that either changed.
Outside the city limits the gaps are wider: Santa Clara County counts 0.3%1 of its locations as unserved, and the California page maps every county.

Checking one address in Sunnyvale
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.
