Corona in California
Corona is a cable city. Spectrum's network reaches 93.9% of its homes and businesses and is the only wired provider offering 100/20 Mbps at 75.9% of them. Fiber reaches 13.0%1, one of the lowest shares among the country's larger cities, and the real alternative to cable here is 5G home internet.
One wire for most homes
Almost every home and business in Corona can get fast wired internet: wired service of 100/20 Mbps or more is reported at 96.4% of the city's 39,695 locations, as of June 30, 2026. Almost none of them can choose between two such wires. At 78.4% of locations exactly one wired provider offers 100/20 Mbps, the 9th highest share among the 343 cities of 100,000 or more, and only 18.0% have two or more. Across California the single-wire share is 43.2%1.

"Only wired option" is the share of locations where it is the single wired provider at 100/20 Mbps. Provider-reported and challengeable; speeds are advertised maximums, not measured; no prices. Satellite providers (Viasat, HughesNet, Starlink) report service at nearly every location and are left out of the table.
The phone network is still copper
AT&T reports service at 91.7% of Corona's locations, but most of it is DSL over copper telephone lines: DSL is reported at 81.9% of locations, the 20th highest share among large cities. AT&T advertises 100/20 Mbps at only 22.9% of locations, and fiber is only part of that: AT&T reports fiber at 12.3% of locations, and the rest of its 100/20 service is DSL advertised at 100/20 Mbps and AT&T's fixed wireless service. Fiber from any provider reaches 13.0%, the 7th lowest1 share among large cities.

Gigabit downloads, slow uploads
The speed figures show how a cable city differs from a fiber city. A 1 Gbps download is advertised at 96.3% of locations, thanks to Spectrum's cable network. But gigabit service with uploads of 100 Mbps or more, the FCC's 1,000/100 tier, is advertised at only 13.6%, and symmetrical 100/100 Mbps service at 13.0%1: both depend on fiber. For video calls, cloud backups and uploads of large files, that upload gap matters more than the download headline. All of these are advertised maximums, not measured speeds.

Where the alternative comes from: 5G home internet
The most widespread alternative to cable in Corona is fixed wireless from the mobile carriers. Verizon reports home internet at 76.5% of locations and offers 100/20 Mbps at 42.8%; T-Mobile reports 72.6%, with 100/20 at 12.0%1. Fixed wireless capacity is shared by everyone on a tower sector, so carriers limit sign-ups by address; the FCC figures show where they report it as available, not where every household could join at once.
What households actually buy
In the Census Bureau's 2025 survey, 84.1% of Corona households subscribed to cable, fiber or DSL (margin of error ±2.7 percentage points), 10.9% relied only on a cellular data plan and 3.1%2 had no subscription. The survey does not record which company a household buys from.
