FCC data as of 2025-12-31
Total broadband serviceable units: 14,448
Satellite is doing 1.1% of the work here
The headline says 100.0% served, but only 98.9% has ground infrastructure at the benchmark. That gap is about 162 broadband serviceable units whose only reported option at 100/20 is satellite.
- Satellite reaches almost everywhere, so a headline that includes it approaches 100% nearly everywhere and stops distinguishing places.
- Availability is not capacity. Satellite constellations share bandwidth across all subscribers in a cell, so advertised speed is not a guarantee the whole reported population could be served at once.
- Latency, weather sensitivity, data policies, and equipment cost differ materially from wired service, and none of them appear in this dataset.
- Funding and policy programmes frequently treat satellite-only locations as unserved for their own purposes. Check the programme's own definition rather than this headline.

Headline versus ground truth
| Lens | Share | Units |
|---|---|---|
| Any technology, including satellite | 100.0% | 14,448 |
| Ground infrastructure only | 98.9% | 14,286 |
| Satellite is the only option at the benchmark | 1.1% | 162 |
Coverage by speed tier
| Tier | Share | Estimated units |
|---|---|---|
| 0.2/0.2 Mbps | 100.0% | 14,448 |
| 10/1 Mbps | 100.0% | 14,448 |
| 25/3 Mbps | 100.0% | 14,448 |
| 100/20 Mbps | 100.0% | 14,448 |
| 250/25 Mbps | 100.0% | 14,448 |
| 1000/100 Mbps | 76.3% | 11,027 |
Tiers are cumulative: a unit counted at a higher tier is also counted at every lower tier, so these rows must not be summed.
Fiber and upload capability
The published summary reports six fixed download/upload pairs and no symmetric tier above 0.2/0.2 Mbps, so symmetric service cannot be measured from it directly. Upload capability is shown through the highest tier, which requires 100 Mbps upstream, and fiber is reported separately because it is the technology that typically delivers matched speeds. A symmetric share is derivable from the FCC location-level availability files, which carry each location's advertised upload speed, but that product is roughly 973 million rows per vintage and is not ingested here.
Every technology
How this compares
Ranked 10 of 14 within State 25 on any terrestrial coverage at the benchmark.
Ranking deliberately uses ground infrastructure rather than the headline. Satellite reaches nearly everywhere, so ranking on it puts most areas at 100% and separates nothing.
