What the FCC Data Shows for Guam

Guam has 2 distinct broadband providers on file with the FCC and 4,577 total deployment records across all technology types. The state's average maximum advertised download speed sits at 40.0 Mbps - above the legacy 25/3 Mbps broadband threshold but below the modern 100/20 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 Guam is led by DSL, with fiber accounting for 0.0% of filings, cable 1.6%, and DSL 98.4%. 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.

TeleGuam Holdings, Inc. files the most deployment records in Guam at 4,502, with NTT DoCoMo, Inc. second at 75. The dominant technology line by filing count is ADSL2+, which alone accounts for 3,604 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.
