Broadband speeds in CF38
Share of CF38 premises by the fastest download speed available, averaged across all 445 postcodes in the district.
98.2% of the 445 postcodes reach superfast, and 90.7% support gigabit. Wireless infrastructure is substantial here at 58%, indicating much of the gigabit footprint comes from wireless backhaul rather than fibre or cable alone. The 30-300 Mbps tier holds 6.7% of postcodes, and below 10 Mbps represents just 0.1%. This postcode shows strong overall depth in network quality, though the heavy reliance on wireless infrastructure means real-world performance may vary by weather and location. Premises with clear line-of-sight will perform well; those obscured by terrain or obstacles may experience variable speeds. CF38's combination of high superfast floor and wireless-heavy gigabit suggests selective investment in ultrafast infrastructure using point-to-point links.
