Fixed wireless offers a no-installation alternative that is increasingly competitive with cable for everyday internet use, with speeds typically ranging from 50-300 Mbps download. Unlike satellite, fixed wireless delivers lower latency (20-40 ms), making it viable for video conferencing and gaming. Satellite internet (Viasat, HughesNet, Starlink) reaches addresses that wired broadband can't. Starlink's low-Earth-orbit (LEO) technology delivers 20-60 ms latency — a major improvement over geostationary services at 600+ ms — making it a practical choice for rural households without fixed-line options.

New Hampshire received $197 million in federal BEAD funding. The New Hampshire Broadband Office is currently in the challenge phase, which means providers and communities can dispute the FCC broadband maps that determine which locations qualify for funding — a critical step before deployment grants are awarded. The Affordable Connectivity Program (ACP) previously provided up to $30/month subsidies for eligible households, though federal funding expired in 2024. Some providers continue offering voluntary low-income discounts.

Market data is based on the FCC Broadband Data Collection (June 2025). Actual coverage and plan availability may vary by specific address within ZIP code 03837.
