I noticed in the article it mentions the current version of OR G.fast will be 106MHz. The new G.fast it mentions that is getting speeds of 2000Mbps seems to be at 212MHz.

In the future once the first version of G.fast is up and running, what would be needed for OR to increase the MHz to 212? Is it just a matter of them turning a dial to allow more frequency and firmware updates, or would OR have to make physical alterations to the network?

New line cards, new CPE and horror of horrors deeper fibre in the network as from cabinet won't cut it.

Indeed. The higher speeds are over very short distances. Good for large apartment blocks, Universities/schools, etc. Very heavily/densely populated buildings, rather than streets/towns. OpenReach will stick with the current G.Fast.

Absolutely. I imagine its primary purpose will be as an overlay to existing VDSL-based FTTB solutions, or an FTTB solution in lieu of FTTP / Ethernet to the apartment in MDUs. It'll also have some value in North America where there are coaxial distribution networks in apartment blocks.

Here, pointless without pushing fibre up to DP depth, which is completely off the table for Openreach until after 2020 and unlikely after that. Far more likely to see a solution similar to their own FTTRN solution or the Swisscom FTTS solution, intercepting copper bundles somewhere in between DP and existing PCP.

Does anyone else have the suspicion that in future the back haul for G.fast nodes might be G.fast from the cabinet?

In theory it should work fine, but is it actually cheaper?
