More than a year late but now in acceptance trials at a large European carrier. 8/16 Everything in the article is accurate as far as I know, except the claim "First results" in the title, now removed. A reader just informed me that Fastweb in Italy is actually in production with 35b and there are some results ion Italian websites 8/20 I thought I had "First results" but in fact Alcatel had published results from KPN testing I had missed. Below.
Original: From chipmaker Broadcom to Nokia and Huawei, everyone promised 35b "Supervectoring" for about a year ago.
Now it's here, and Kevin Schneider’s lab tests at Adtran found “mid to high 200’s @ 1,000 feet.” Talking with Kevin, I didn't sense any major anomalies in his testing at other distances. Until now, 35b speeds were estimated based on simulations like the chart here. These early test results are very encouraging. The hope is they can move to field trials in Q4 and soon after to deployment.
35b is essentially vectored VDSL 17b MHz extended to 35 MHz. Initially, the industry thought G.fast from close-in distribution points would be the standard upgrade. With volume production and some competition, the price of G.fast equipment will fall to very little more than VDSL. 35b is close to G.fast speeds from around 300 meters to around 450 meters, but much slower for shorter distances.
