Brookings, SD has a highly concentrated broadband market (HHI: 41,743) where Viasat dominates with 100% coverage reach — 0 percentage points ahead of the next-largest provider, HughesNet at 100%. In highly concentrated markets, consumers typically see fewer promotional offers and less pressure on the leading provider to invest in network upgrades. The remaining 6 providers in Brookings, SD cover a fraction of addresses, limiting their competitive impact. Research from the FCC shows that markets with one dominant provider average higher monthly costs compared to markets with two or more meaningfully overlapping competitors. Fiber internet is available from 2 providers (AT&T Internet, CenturyLink), with 31% fiber coverage — below the national average of 57%. Fiber delivers symmetrical upload and download speeds — a key advantage for households with multiple remote workers, video conference participants, or content creators who upload large files. Nationally, fiber represents the fastest-growing broadband technology segment, expanding at roughly 8 percentage points of coverage per year. Mediacom provides the primary cable broadband alternative with 79% coverage — above-average cable coverage 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. For households that do not require heavy upstream bandwidth, cable plans often offer competitive pricing to fiber. Fixed wireless internet — including 5G home internet services — is available from T-Mobile and AT&T Internet, reaching 66% of addresses (well above the national fixed wireless average of 32%). 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) provides universal coverage as a last-resort option for addresses outside wired broadband service areas. Low-Earth-orbit (LEO) satellite from Starlink has improved latency to 20-60 ms, a significant improvement over geostationary services (600+ ms), making it a practical alternative for rural households without viable fixed-line options.

Fiber-optic internet availability in Brookings, SD stands at 84% — 27 percentage points above the national average of 57%. This exceptional fiber penetration places Brookings, SD among the top-tier U.S. markets for FTTH (fiber-to-the-home) deployment. Residents here benefit from the fastest, most reliable internet technology available, with symmetrical upload and download speeds that support remote work, 4K streaming, and large household bandwidth demands without compromise. Cable broadband reaches 96% of addresses — 24 points above the national cable average of 72%. Strong cable coverage ensures most households have access to speeds of 100 Mbps or higher, making cable a reliable fallback even where fiber has not yet arrived. Fixed wireless internet — including 5G home internet from T-Mobile and Verizon — covers 66% of addresses, 34 points above the national fixed wireless average of 32%. Higher-than-average wireless availability gives residents an additional competitive alternative that can keep wired ISP pricing in check. 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.

South Dakota received $208 million in federal BEAD funding. The South Dakota GOED Broadband 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.
