Copenhagen Expands Fiber and 5G Networks Across City
Current coverage levels and measured speeds provide the base for continued expansion of reliable digital access in the city.
How we reported this
Copenhagen maintains fiber internet at 77 percent coverage alongside 88 percent DSL broadband coverage and 100 percent mobile broadband availability, forming the platform for future service improvements. Average download speeds sit near 215 Mbps with uploads at 137 Mbps, while median figures reached 134.7 Mbps download and 112.3 Mbps upload in the twelve months ending March 2025.
Why Current Infrastructure Supports Next Steps
These metrics matter because they underpin remote work and digital services that depend on consistent connections. A city score of 90 out of 100 for internet speed reflects the combination of fast fiber options and mobile coverage that residents already use for everyday tasks. The presence of these networks means providers can focus upgrades on areas still served by older connections rather than building coverage from scratch.
Neighbourhood Differences in Newer and Older Areas
In newer developments such as Ørestad and Nordhavn, fiber connections are already installed as standard. Older buildings more often use coax supplied by providers like YouSee when fiber installation proves difficult. This split shows where future fiber rollout can target specific streets and properties without duplicating existing mobile broadband that reaches every part of the city.
Measured Speeds and 5G Reach as Indicators
Basic 5G signal covers virtually all of the population as recorded in 2023, with high-band 5G available to 85 percent. Users on 5G phones have seen speeds regularly above 300 Mbps by 2025. These figures, drawn from network tests, indicate that mobile networks can carry additional load as fiber extends further into existing buildings.
Practical Steps for Residents and Businesses
Households and offices can review their current provider options against the known fiber availability in their building type. In areas where coax remains the default, checking with local operators about fiber upgrades offers a direct route to higher speeds. The existing 100 percent mobile broadband footprint means fallback connectivity stays available during any transition periods.
