Broadband speeds in CO2
Share of CO2 premises by the fastest download speed available, averaged across all 931 postcodes in the district.
Gigabit reaches 85.8% of postcodes, with 12.7% bridging the 30-300 Mbps gap. Only 0.2% drop below 10 Mbps and 0.1% miss uso targets entirely. Wireless is notably abundant at 7.9%, a sign that certain urban quarters rely on wireless backhaul or last-mile links instead of trenching new cable. This mixture of cable gigabit and wireless backup reflects dense town geography: wired infrastructure dominates the core, but wireless fills gaps in older residential patches or areas where property costs make excavation expensive. The diversity of network types means that whilst most postcodes enjoy modern high-speed cable, a minority depend on wireless technology. Both are professional installations with reliable performance. Urban density supports multiple solutions; rural areas are not so fortunate. Colchester's CO2 is fundamentally well-wired despite the wireless contingent.
