Cable is the backbone here. It reaches 96.8% of Juneau City and Borough, concentrated in the towns. Outside the cable footprint the picture changes sharply, which is why the address matters more than the county.
Everything below comes from the FCC's Broadband Data Collection, the filings providers are legally required to make about where they offer service. It describes the county; your own address can differ, and that is exactly why the technology mix matters.

What that means if you live here
The USDA classes Juneau City and Borough as a nonmetro county with an urban population of 20,000 or more, not adjacent to a metro area (continuum code 5).
About 31,973 people live across those locations, roughly 3.2 people per serviceable address.
Only 271 locations, 2.7%, are recorded with nothing at 25/3 Mbps or better.
The most widely available technology here is cable, reaching 9,572 locations (96.8%); next is licensed fixed wireless at 30.4%.
Practically no fiber has been built here. The filings show 45 locations reached.
Licensed fixed wireless covers 30.4% of the county. It does not reach as far as cable does here, but it reaches places cable does not.
Cable reaches 96.8% of locations, more than fiber does, and it will be concentrated in the built-up parts of the county.
Filings come from 7 providers, of which 2 offer fiber and 2 licensed fixed wireless.
Served locations rose 0.27% year on year.
That is better than the typical Alaska county, whose median unserved share is 23.6%.
Fiber lags the rest of Alaska, where the median county is at 16.7%.
What people actually measure in Alaska
Median of real speed tests run on each network during 2024, from M-Lab. This is measured performance, not an advertised plan speed, and not a customer review. The middle-half column shows how consistent a network is: a wide spread means your experience depends heavily on where and when.

Latency is the number that decides whether video calls and gaming feel right, and it is where satellite differs most from everything else. Measured data is statewide: below county level there are usually too few tests to report an honest number.

Your realistic options in Juneau City and Borough
Fiber
Fiber, if it has reached you
The best outcome by a distance: symmetric speed, low latency, no weather sensitivity, no data ceiling in practice.
Best for
Anyone whose address is inside a fiber build. Always check this first.
Watch out
Coverage stops abruptly at the edge of a build. Being a mile from fiber is the same as being fifty.
Fixed wireless
A local fixed-wireless provider
A regional operator beaming service from a tower or ridge to an antenna on your roof. In much of rural America this is the fastest thing available.
Best for
Counties where the FCC data shows large licensed fixed-wireless coverage, which this page tells you
Watch out
Needs line of sight. Quality varies enormously between operators; ask neighbours, not the sales page.
5G home internet
T-Mobile Home Internet
Home internet over T-Mobile’s cellular network. A gateway box you plug in yourself; no truck roll, no dish.
Best for
Rural addresses that still get a usable T-Mobile signal, often near a highway or a town
Watch out
Availability is decided address by address, not by town. Speed varies with how busy the local tower is.
