Shares are the percentage of this state's Form 477 deployment records using each technology category.
Connecticut has 19 distinct broadband providers on file with the FCC and 405,229 total deployment records across all technology types. The state's average maximum advertised download speed sits at 147.5 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 Connecticut is led by satellite, with fiber accounting for 1.5% of filings, cable 13.2%, and DSL 36.9%. 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.
Frontier Communications Corporation files the most deployment records in Connecticut at 152,755, with ViaSat, Inc. second at 67,578. The dominant technology line by filing count is Satellite, which alone accounts for 196,356 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.
