Next up: We have BT's G.fast Obfuscated, Bamboozled 'upto' Ultrafast Broadband speeds.
Here in the UK, we have ended up in a situation, employing a whole army of Ofcom regulatory pen pushers to work out what subscribers might get 'upto', rather than a whole army laying true fibre optic cables, which mean none of those pen pushers are needed. So much time and energy is wasted trying to work out 'upto' BT FTTC/ADSL copper based broadband speeds.
BT needs to start (likely forced) to connect subscribers/homes more than 500m by cable length (250m as the crow flies) to real Fibre Optic cables now (starting with a long term end of life replacment programme copper -> FO + all new housing developments/builds) if BT is to remain robust/relevant to possible regulatory changes in the pipeline aka 'even-equal distribution' across all parts of its network for any future ultrafast rollouts, to meet Britain's future needs.
250m by cable length is probably the 'sweet spot', regards G.fast via legacy copper/alu v true Fibre Optic rollout costs, but BT needs to start somewhere, so 500m by cable length allows for some technology improvement in G.fast (given BT have become biased/love struck on G.fast via legacy copper/alu as their solution to supplying Britain with 'upto'* Ultrafast Broadband, remember this is in no way 'blanket Ultrafast' coverage BT are proposing, its 'cherry picking' obfuscated/bamboozled 'upto' Ultrafast Broadband speeds.
Even if BT is obsessed with using G.fast technology for certain parts of its rollout. At >500m (I'd be nearer >250m mark) by cable length there is little question true fibre optic technology is the only real reliable way (all factors-speed, reliability, weather, TCO/maintenance) to achieve blanket ultrafast coverage, without obfuscated bamboozling 'upto' Broadband speeds for everyone, with no real way to work out what a subscriber might expect day to day.
BT have a generation/Brand problem too, because more and more people will begin understand the underlying technical reasons why their obfuscated/bamboozled 'upto' Ultrafast Broadband really isn't 'blanket coverage' FTTC 80Mbps/G.fast 300Mbps because of the underlying 'upto' G.fast technology that was chosen. BT (and regulator Ofcom) will be resented for it, more and more going forward, for choosing 'cheap'. The Brand will suffer (more than it already does).
BT can't keep sprouting that G.fast is the solution for the complete BT network, you can't keep penalising certain subscribers / 'cherry picking' the easy to install ones due to where they live (both urban and rural - through no fault of their own) because biased BT thinking and legacy copper cabling means its voiced as 'difficult-expensive' to provide a high speed services to those customers.
Fibre optic technology is been rolled out elsewhere in the World without all the fuss BT seem to sprout (so there is no excuse for BT going forward) to remove the distance 'upto' element to these 'difficult-expensive ' (as BT loves to describe them) subscribers.
If BT chooses now to base its future on G.fast, then its laying itself open to be fined for failing to meet future rising USO (Universal service obligation) going forward.
BT either wants homes more than 500m from the FTTC/'Exchange' as subscribers or they don't and if they don't, these 'difficult' subscribers and oversighting local authorities shouldn't be held to ransom by the incumbent sitting on its hands with bamboozling/obfustcated proposals of 'upto' Ultrafast broadbands speeds via legacy copper, that just don't work at these distances, for these subscribers, predominately in rural locations/Market 1 exchanges.
The regulator needs to force 'even distribution' irrespective of the difficulty of supplying any future technology upgrades to longer lines, G.fast can't be seen to again, to cherry-pick 10m subscribers closest to the FTTC Cabinet, just so the regulator Ofcom/BT can say "look we have 10m 'upto' ultrafast connections".
Even distribution across all parts of the network, in all localities is just as important today, going forward for those new 10m ultrafast connections.
In the future, if BT want to upgrade 2/3rds of its subscribers to Ultrafast Broadband Ofcom/Openreach rule changes should mean that these 2/3rds need to be distributed evenly across the UK and across all areas of its network, not just the easy upgrades by replacing line cards in exisiting FTTC cabinets, to facilitate subscribers nearest the cabinet, but customers more than 500m from an FTTC too.
(See the Thinkbroadband article:
on the rollout of G.fast to 10m subscribers and look at the current UK distribution model, using the likely unimaginative BT 'bog standard' line card replacement model in existing FTTC cabinets).
Crucially G.fast under this proposal offers existing Notspots, lines more than 500m by cable length absolutely nothing, (and very little to those 250m-500m from the existing FTTC cabinet)
