CF99 is Cardiff's sole outlier postcode, served entirely by wireless services and no wireline broadband infrastructure. All metrics register zero except the 100% wireless coverage.
Broadband speeds in CF99
Share of CF99 premises by the fastest download speed available, averaged across all 1 postcodes in the district.
Only one postcode carries the CF99 code in Cardiff, and it is served by wireless alone, with no superfast, no gigabit, no traditional broadband routing to this location. This is an edge case where postal address infrastructure exists but wireline networks have not reached. Wireless at 100% means this one location depends entirely on that technology for broadband. All other speed bands register zero. This single outlier likely represents a business address, isolated building, or postal boundary quirk rather than a neighbourhood broadband gap.

CF99 broadband FAQs
What does 100% wireless and 0% everything else mean?
This one postcode has wireless connectivity only, no cable or fibre line. It's either a remote location or an administrative boundary edge.
Is wireless reliable enough for work-from-home?
Wireless can support remote work if signal quality is strong. You would need to test throughput and jitter before committing to home office use.
Can I request fibre or cable here?
With only one postcode in CF99, providers likely view it as uneconomic to build new wireline infrastructure. Your best route is to confirm wireless performance.
Why does this postcode exist if broadband coverage is so limited?
Postal codes exist for mail delivery, not broadband rollout. CF99 may represent a single address or building whose data persists in the postcode database even if broadband deployment priorities have not prioritized it.
