CF83 broadband FAQs

Why does CF83 have so much wireless coverage?

42.2% coverage suggests active deployment as either primary or backup infrastructure. When a district this large is well-served by cable and fibre, wireless often rolls out to capture remaining edges or offer customer choice.

Is gigabit the real story or is mid-speed growth the story?

Gigabit is available to 88.6%, but most households operate comfortably on the 30 to 300 Mbps tier (8.4% of postcodes). The real story is that 97.9% reach superfast minimum; everything else is margin and preference.

Should I worry about the 0.4% below 10 Mbps?

With 1,189 postcodes, 0.4% represents four or five postcodes. If you're not in one, broadband is abundantly available locally.

What speeds will I realistically get?

The median household falls into the 300 Mbps-plus tier where measured speeds often exceed 100 Mbps downloads. Only a small minority are constrained to 30 to 300 Mbps or slower.
