Broadband speeds in LL77
Share of LL77 premises by the fastest download speed available, averaged across all 245 postcodes in the district.
A transitional zone between lagging and premium tiers. Gigabit capacity sits at 39.4%, leaving 47.9% in the superfast 30-300 Mbps band. Below-superfast affects 6.9%, a moderate proportion. Below-USO stands at 1.6%. Wireless is moderately present at 20.1%, suggesting wireless complements fixed infrastructure in parts of the area. Investment here lags the top-tier zones, but far outpaces slower areas. Most homes sit on superfast copper or cable delivering mid-tier speeds. Gigabit remains limited to two in five postcodes. Households with heavy broadband demands will find solid but not premium experience. The speed distribution reflects ongoing rollout without saturation. Some premises enjoy gigabit. Others experience legacy network constraints. The moderate wireless penetration suggests peri-rural deployment where wireless fills gaps between cable nodes. The zone offers reasonable performance for most but not universal premium access.
