If you're setting a target 8 years out then you might as well say gigabit which in practise means fibre, because 60Mbps FTTC is going to be insufficient by then. It also rules out fixed wireless which is good because it stops someone just buying a load of Ubiquiti radios and hoovering up public funds to deliver crap.
It really doesn't though... in some areas 5g & even 4g wireless crap exceeds fixed lines in the UK already.
Fibre isn't the only avenue... updated DOCSIS is already multi-gigabit as has been for years before Virgin pushed their first gigabit product. Due to conversions and longevity, its growth is only fuelled by ongoing provider avoidance of real fibre deployment.
The viability of a strong wireless network is a far more efficient deployment method... real wireless PTP links have been in the 10g+ range for 5 years or more already at relatively low expense... general bandwidth sharing has long-since opened it up as a much more cost-effective deployment method than laying cable.
Unfortunately I feel the starlink system will deploy such a service to the UK before any local provider unless 1 takes the lead and the others are forced to follow suit... but even then... the providers will file anti-competitive lawsuits before they ever actually provide a competing product.
The public funds have the capability to deploy appropriate connectivity... but of course it's better to create artificially inflated population density hotspots only to allow below-average earners to compete in a growing market.
The UK continues down its slow path of new-market death.
But of course... artificially inflating the GDP to unsustainable levels is the best way to borrow the country into bankruptcy at the expense of its population... ever since Brexit, the UK has been high on my list for the "next" pre-WW2 Germany-like economy... it's only taking longer to get there. Hopefully it avoids it... but Brexit was a strong nail in the coffin. I believe in democracy, but its difficult to vote on an issue of country-level-cooperation when the most powerful group of voters never left their home town, don't intend to and lack the education to tell their arse from their elbow...
In current markets, let alone future... the economy-boosting potential of deploying good connectivity to even remote locations has far outweighed the cost...
All the UK is really doing, is managing its basic tickboxes before a non-local company can deliver a better product from orbit...
