What people actually measure in New Hampshire

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 Belknap County
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.
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.
