I am pretty sure Alcatel uses "VPLUS" which is still 35b. Or maybe thats Alcatel AND/OR Nokia.
Thats the way I'm taking it right now. whatever the vendors call the technology, it appears to more or less achieve the same aim.
I think this happens with quite a lot of emerging technologies. Heck even G.INP is known under several names.
I just used Alcatel as an example to Max, to say that Openreach aren't just limited to using Huawei.
Pass.
Me neither. It does however seem odd that when ECI really were at the forefront (first) at manufacturing system based vectored DSLAMs that all is quiet when it comes to 35b.
Since their website has gone all elastic [not sure if I like that term, but supposedly they use it because it means
expandable and adaptable to change] it's much harder to find resource pages.
ECI appeared to favour Lantiq, but I'm not sure where that leaves them on older equipment since the buy out by Intel.
Intel is also jumping in on VDSL2 35b chips, but their blurb calls it
VDSL2 AnnexQ (35b)This would fundementally mean that G.fast would yet again require some alterations to work with existing technologies. Currently it is 19-106 MHz, but with 35b in place it would need to be something like 37-106 MHz which would even more reduce coverage and make it limited to probably maximum ~100 meters for 330/50 Mbps DS/US. It would HAVE to be installed at DPs in this scenario as the distance would be far too limited to even think about putting it as a pod on a cabinet.
Yup exactly. As it stands they arent compatible because of the 'shared' frequencies. Rolling out 35b in a g.fast area is going to be detremental.. not only would/could it reduce distance, but also the attainable speeds of properties that already have g.fast.
This is why until FTTP is available nationwide, I said they may have to do a mix of technologies depending upon what is judged best for a particular locale.
Sorry too weary to go searching for something what I read ages ago - so the following may not be accurate, but some countries (Austria?) were going 35b, some g.fast.. and some (Australia?) considering mixed.
We don't have a crystal ball so who knows what Openreach are going to do, but the fact that just this week they announced change in plans for g.fast makes me think something is afoot. They said they plan to install more FTTP, but that still leaves quite a large shortfall of iirc a few million homes without speed improvements when compared to the original plans.
In the past few years, the newer emerging technologies such as 35b and TVWS* may have made them have a rethink..... or maybe not :/

*They did say that they would consider WIFI for harder to reach areas. Since TVWS uses lower frequencies and has more penetration, then that could be an option too. Who knows :/
