What the FCC Data Shows for South Carolina
South Carolina has 37 distinct broadband providers on file with the FCC and 894,959 total deployment records across all technology types. The state's average maximum advertised download speed sits at 181.4 Mbps - at or above the federal 100/20 Mbps broadband benchmark. That headline figure is the mean across every filing, so it weights provider-by-census-block records equally rather than weighting by population, which means rural filings pull the average as much as urban ones.
The technology mix in South Carolina is led by satellite, with fiber accounting for 4.7% of filings, cable 13.2%, and DSL 22.0%. Fiber share is the single best indicator of future-proofed infrastructure because fiber supports symmetric multi-gigabit speeds and scales without rewiring; cable share signals incumbent coverage in suburbs and cities; DSL share typically correlates with legacy copper footprints in smaller towns and rural pockets where no newer technology has arrived yet.
ViaSat, Inc. files the most deployment records in South Carolina at 181,908, with Hughes Network Systems, LLC second at 172,067. The dominant technology line by filing count is Satellite, which alone accounts for 526,042 records. Remember that Form 477 counts provider filings, not homes actually connected, so a block with five providers shows up as five records, useful for measuring competition and coverage breadth, but not a direct proxy for subscriber counts or real-world speeds at any specific address.
