Miami and the surrounding south Florida metro have stronger carrier choice than they did five years ago. AT&T Business Fiber covers a growing share of commercial blocks. Comcast Business is everywhere. Hotwire Communications has a strong presence in some buildings. Crown Castle and Lightpath both have meaningful fiber footprints in the metro.
The pricing problem in Miami is the seasonal contract cycle. Many businesses sign 24 or 36-month contracts in the summer hiring slowdown and never look at them again, which means the auto-renewal hits at the busiest part of the season.
Miami's commercial center
Miami's commercial demand sits in three big places. The Central Business District holds the legal, banking, and government corridor along Flagler Street and Biscayne Boulevard. Brickell, just south of the Miami River, has filled in over the past two decades as the metro's largest concentration of Latin American banking and Class A office tenancy. The Arts and Entertainment District, north of the CBD, anchors a mix of cultural institutions, hospitality, and creative-office tenants. Jackson Health System, the public-hospital network covering Miami-Dade County, and the University of Miami's Leonard M. Miller School of Medicine are two of the largest commercial accounts in the metro and drive a substantial share of enterprise telecom demand.
In 2025, Lightpath expanded its Miami network to connect the Hollywood Cable Landing Station and said its Miami system had grown to more than 80 route miles of underground fiber, adding meaningful local fiber capacity for international and data center traffic. One pricing wrinkle: The Miami Downtown Development Authority is funded by a special tax levy on properties within its district, which adds a district-specific cost layer for downtown owners and businesses, often passed through in commercial leases.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail.
Miami dedicated internet, typical retail (mid 50%)
Monthly recurring charge, dedicated internet access (DIA). Numbers are derived from current carrier wholesale quotes.
| Speed | Typical retail (mid 50%) | Sample size |
|---|---|---|
| 100 Mbps | $630 – $765/mo | n = 1 |
| 500 Mbps | $955 – $1,160/mo | n = 1 |
| 1 Gbps | $1,195 – $1,455/mo | n = 1 |
| 10 Gbps | $2,190 – $2,660/mo | n = 1 |
If your bill sits above the high end of the band, you are likely overpaying.
Analyze My Bill FreeFor AT&T Business Fiber broadband, a 1 Gbps line should land between $180 and $260 a month. For Comcast Business coax at 600 Mbps, expect $150 to $230. Anything above $310 on coax is a sign of an aged contract.
Carriers worth quoting in Miami
Six carriers cover most addresses in the metro.
- AT&T Business Fiber. Strong commercial fiber footprint, especially in Brickell, downtown Miami, and the Aventura area.
- Comcast Business. Coax everywhere, fiber in select buildings.
- Hotwire Communications. Strong building-specific footprint, especially in Brickell condo towers and select commercial properties.
- T-Mobile Business Internet. $85 a month for 200 to 300 Mbps. Useful benchmark.
- Crown Castle Fiber. Common in downtown commercial buildings.
- Lightpath. Now expanded into south Florida, mid-market fiber.
If you have not had three of these on a quote sheet, you have not run a real comparison.
