Denver's Dual Fiber-Cable Networks Enable Gigabit Speeds for Tech Industries

Denver posted a median fixed broadband download speed of 257.15 Mbps and upload speed of 49.82 Mbps as of January 2026, placing the metro among elite performers for cities of its size according to BroadbandMap data.

Those numbers matter now because companies that rely on rapid data movement, from software development to cloud operations, favor locations where residents and offices can count on consistent high throughput without frequent bottlenecks.

Fiber providers set the pace

Quantum Fiber supplies symmetric speeds up to 8 Gbps across 51.2 percent of Denver, the widest fiber footprint among local carriers. CenturyLink Fiber matches the 8 Gbps top tier but reaches only about 10 percent of addresses, while its standard fiber tier tops out at 940 Mbps with unlimited data. Xfinity blankets 95 percent of the city with cable service that reaches 2 Gbps, and its Connect plan delivers 150 Mbps for $20 per month.

The combination gives businesses and households choices between fiber symmetry for upload-heavy work and cable reach for quick deployment in most neighborhoods.

Wireless fills coverage gaps

Fixed wireless 5G options extend access further. T-Mobile covers 90.8 percent of Denver at speeds up to 64 Mbps, Verizon reaches 70.6 percent with peaks near 438 Mbps, and AT&T serves 66.7 percent up to 48 Mbps. These services let users outside core fiber zones maintain connectivity for lighter tasks.

Local tech firms can therefore locate staff across a wider area while still meeting performance needs for video calls, large file transfers and remote collaboration tools.

Residents and companies seeking service can compare current offers directly from each provider’s site or through aggregator listings such as BroadbandNow to match speed and price to their address.
