A reader wondered about my 35b story writing, "35b to my knowledge is already in market." I know Fastweb in Italy is already selling to consumers at "Up to 200 megabits" but without vectoring they will often be much lower. On the other hand, Deutsche Telecom, the largest expected customer, says it won't be ready until 2019. I believe what's going on is that Broadcom is selling 35b chips but the vectoring isn't ready for large deployments, but the primary sources aren't providing answers.
The reader, wanting to be confident, asked what were my sources for the story Deutsche Telecom: 35b Supervectoring Delayed to 2019? That's always a fair question.
I've been reporting 35b since 2015, but this story was inspired by an article by Achim Sawall Super Vectoring kommt bei Telekom erst im Jahr 2019. (250 MBPS:Super Vectoring will not be available at Telekom until 2019) (All translations by Google.)
"Super Vectoring with data transfer rates of up to 250 MBit / s will only be available at Deutsche Telekom in 2019.
