> You need a totally different design if BT errs cautiously and designs/implements for the next USO instead - 30Mbps, but guarantees 10Mbps, 2020.
Any solution that BT can come up with today to provide 10M, will in most cases be able to provide 50M+ anyway.
- for remote villages or clusters of properties, where all properties are within 500m of some central point X: fibre up to that point, and do VDSL/G.fast
- for individual remote properties: fibre up to the property
The 10M-30M range only applies to properties on copper lengths of 1 to 2.5km. If you're sticking a new cabinet somewhere that remote, then it will likely be prohibitively expensive to get power to it.
