https://www.ispreview.co.uk/index.php/2019/05/openreach-work-hints-100mbps-at-500-metres-on-g-fast-broadband.htmlOpenreach (BT) is slowly progressing with a future upgrade of their hybrid-fibre G.fast broadband technology, which could enable the service to harness some of the existing radio spectrum frequency being used by VDSL2 based Fibre-to-the-Cabinet (FTTC) lines. Early tests show a possible boost to speed and coverage.
After reading the article it talks about the impact in frequencies of running both VDSL2 and G.fast along side each other and how they have to kept seperated.
Can someone tell me how the frequencies are interacting with each other considering that G.fast lines are coming from a seperate pod that is vectored? Does the interference come from when the copper lines come away from the cabinet and they are side by side?
While it is good they are trying to squeeze the best possible performance from the G.fast technology in the limited deployment that OR have used it, I still find it a waste of time to be 1. focusing on a service only a limited amount of people can benefit from (and an even smaller number were the connection will be stable at high speeds), and 2. that there is such a low take-up.
The original problem of powering G.fast lines that stopped OR deploying it further in to the community was solved by an Israeli company years ago. I remember seeing a video demostration of it. There is still nothing to stop OR going back to their original plan of deploying it to poles and manholes as they push their fibre network further out.
I think when these survey's are done about broadband connections in areas, they should move away from using the average speeds, and also the advertised speeds and use a sample of actual real life connections. Because I've heard it said that the reason G.fast is being deployed to cabinets is to increase the overall average speeds in that area. But my issue is that if 1. very few people are actually using G.fast, and 2. when they do they aren't getting the full speeds, then the survey's are showing a false picture i.e. making out that the speeds available in an area is higher than they are in reality. Which is good for marketing, but not good for the customers as its misleading advertising imho.
