Internet in Cambridge, Massachusetts
Fiber is available at 0.5% of the 12,191 homes and businesses the FCC counts in Cambridge, and wired broadband of at least 100/20 Mbps at 99.9%. 6.3% of locations have a choice of two or more wired providers at that speed; at 93.6% there is only one.1
FCC National Broadband Map, availability as of June 30, 2026 (data revised November 10, 2026), as reported by providers.
Cambridge in Massachusetts
Cambridge has one wired network at most of its addresses. Xfinity reports cable service at 99.9% of the city's homes and businesses and is the only wired provider offering 100/20 Mbps at 93.6%, the 3rd highest single-provider share among the 343 US cities of 100,000 or more. Fiber is reported at 0.5%1 of locations.
Xfinity's cable network and little else wired
As of June 30, 2026 (FCC revision of November 10, 2026), Xfinity reports service at 99.9% of Cambridge's 12,191 homes and businesses, over cable, with downloads advertised up to 2 Gbps. Astound, the only other wired company with more than a handful of listings, reports cable at 6.1% of locations (737 in all). Verizon, whose Fios network reaches 86.6% of Boston, reports fiber at 0.2%1 of Cambridge locations; its listings here are almost all fixed wireless. Satellite services report the whole city, as they do everywhere, and are left out of the choice counts below.

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 (Viasat, HughesNet, Starlink) report service at nearly every location and are left out of the table.
A provider's listing means it told the FCC it serves the location or could connect it within ten business days of a standard request. The figures cover Cambridge's city limits as drawn for the 2020 Census, and a listing that turns out to be wrong can be challenged on the FCC National Broadband Map.
One wired choice at most addresses
At 93.6% of locations, 11,409 in all, exactly one wired provider offers 100/20 Mbps, and at 93.6% that provider is Xfinity. Across Massachusetts the single-wire share is 43.7%, and nationally 36.6%. Two wired choices reach 6.3% of Cambridge locations, about the size of Astound's footprint, and three or more 0.0%1.

Across the Charles River the map looks different. In Boston, where Verizon's fiber runs beside Xfinity's cable, one wired provider is the only option at 8.4% of locations and three or more reach 50.4%. Quincy, south of Boston, has a single-wire share of 90.1%1, closer to Cambridge's.
Little change since 2022, except copper
The first National Broadband Map, with data as of June 30, 2022, showed the same structure: one wired provider at 100/20 Mbps at 92.5% of locations and fiber at 0.3%. Wired service of 100/20 Mbps or more from any provider went from 98.3% to 99.9%. The larger change was copper: DSL was reported at 49.1%2 of locations in 2022 and at 0.0% in 2026, tied for the lowest1 share among large cities.
Source: FCC, National Broadband Map, data as of June 30, 2022; FCC, National Broadband Map, data as of December 31, 2025; FCC, National Broadband Map, data as of June 30, 2026. Shares of broadband serviceable locations in each FCC release (latest revision of each); the small number is the change in percentage points since June 30, 2022. The FCC's count of locations is updated with each release, so shares are compared rather than counts.

| Measure | June 30, 2022 | December 31, 2025 | June 30, 2026 | Change (points) |
|---|---|---|---|---|
| DSL available | 49.1% | 0.0% | 0.0% | −49.1 pts |

| One wired choice | 92.5% | 93.8% | 93.6% | 1.0 pts |
The FCC's list of locations is revised with every release, so the comparison uses shares rather than counts. Over the four years the city's count of locations changed little (+1191).
Gigabit uploads on cable
A 1 Gbps advertised download was already reported at 98.3% of locations in 2022. What changed is the upload side. The FCC's 1,000/100 tier, a 1 Gbps download with uploads of at least 100 Mbps, went from 0.0% of locations to 78.0%, and symmetrical wired service of 100/100 Mbps from 0.3%2 to 78.0%1. With so little fiber in the city, those gains are on cable.
In 2026 the fastest advertised download is 2 Gbps or more at 77.9% of locations. Across Massachusetts, the 1,000/100 tier is advertised at 68.4%1 of locations. These are maximums providers advertise to the FCC, not measured speeds.

Fixed wireless as the second option
For a household that wants an alternative to Xfinity, the realistic candidates are wireless. Licensed fixed wireless, which includes 5G home internet, is reported at 97.9% of Cambridge locations, from 51 providers, and their reported speeds differ widely:
- T-Mobile lists 89.8% of locations, with 100/20 Mbps at 46.7% and a maximum of 100 Mbps.
- AT&T lists 69.7%, all fixed wireless, with 100/20 at 4.9%.
- Verizon lists 58.3%, with 100/20 at 26.6%.
- Starry lists 26.1%, with 100/20 at 26.1% and up to 1 Gbps advertised.
- Netafy lists 18.3%, mostly over unlicensed spectrum, with 100/20 at 18.0%1.
Fixed wireless is the only 100/20 option at 71 locations, and no location depends on satellite alone. Wireless capacity is shared on each tower or rooftop sector, so a listing is a starting point and the carrier's address check decides.
Buildings, households and what they subscribe to
The FCC counts 12,1911 locations in a city of 122,5884 residents, while the Census Bureau's 2025 survey counts 50,2775 households. The FCC's unit is the building or house: an apartment block or a two-family house is one location, so the shares on this page describe structures, not individual apartments.
In that survey, 86.7% of Cambridge households subscribed to cable, fiber or DSL (margin of error ±2.3 percentage points), compared with 81.4% across Massachusetts. 8.1% relied only on a cellular data plan (±1.9 percentage points), against 12.2% statewide, and 3.2% had no internet subscription (±0.9 percentage points5), down from 9.2% (±2.2 percentage points6) in 2019.
Source: FCC, National Broadband Map, data as of June 30, 2026; Census Bureau, American Community Survey 2025 1-year detailed tables. Availability is a share of locations as of June 30, 2026 (FCC); subscriptions are a share of households from the American Community Survey, 2025 (whiskers: 90% margin of error).

Checking one address in Cambridge
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.
