Outdoor 5G reaches 97% of Diss, but 2% of homes get no indoor 4G from any network, so a mobile backup here wants a window.
The two 5G figures differ. “5G availability” is everyday 5G running on the existing 4G core, which is what most phones show. “Next-gen 5G” is standalone 5G: a full 5G network with lower lag, still reaching fewer places.
