Established cable networks serve the majority of households, while fiber availability continues to expand from regional and national carriers.

With a median household income of $94,125, Gaithersburg residents are well-positioned to access premium fiber and gigabit plans.

Fiber internet is available from 4 providers (Verizon Fios, Xfinity, AT&T Internet), with 80% fiber coverage — significantly above the national average of 57%.

Xfinity provides the primary cable broadband alternative with 77% coverage — cable coverage in line with the national average of 72%. Cable internet uses DOCSIS 3.1 technology to deliver download speeds of 100 Mbps to 1.2 Gbps, though upload speeds (typically 10-35 Mbps) lag behind fiber's symmetrical performance.

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 (HughesNet, Starlink, Viasat) 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.

This area has exceptional fiber-optic penetration, well ahead of the national trajectory. FTTH (fiber-to-the-home) availability nationwide has grown approximately 8 percentage points annually since 2022, driven by BEAD infrastructure investments and private carrier expansion.
Maryland received $267 million in federal BEAD funding.
