Not my forte at all ...... the technologies that is ........ but our Chief Engineering department, via a nationwide road show for all engineers, were pretty confident G.Fast would work pretty well up to 200/250mtrs and were testing at reaching to 300mtrs using whatever magic these guys have at their disposal.
Forward powering will be the method deployed.
I'm sure I recall something about 106/116Mhz spectrum being involved ?? I may have this wrong, as it is purely from memory and there was a lot to take in.
As we all know by now, VM's network was incredibly selective when first put in the ground. OR don't have the same liberties as such. I don't think the big game plan is to compete at the speed levels VM's network
should be capable of, (but isn't, due to poor backhaul), the predictions of 120Mbps DS speed requirements by 2025 is what our boffins mentioned. Having a Gig to hand is pure waste.
However it pans out, the impression I got from them stood there in front of thousands of engineers and all levels of management, was they are fully committed to G.Fast and saying,
"I can't see BT installing g.fast nodes every 200m in urban areas - that IS what it'll take to "compete" with FTTP speeds" is of course an opinion, and purely speculative.
I've seen lots of speculation on this forum through debate, most of which tends to be proven otherwise. I hope this is the case with your assumptions too, Riz ??.
