Sckipio proves G.fast is not just downstream only. I've never heard of broadband that is faster on the upstream than the downstream in 17 years reporting. G.fast can swing either way, devoting up to 90% of the total bandwidth (typically, 250-800 megabits) to either upstream or downstream. Current proposals in standards will allow the telcos to switch the ratio on the fly based on traffic demands.
I would be delighted to pay extra for a service like that. I'm finding it incredibly convenient to store and backup everything to the Amazon Cloud. I can find things right away whether I'm in my place, Jennie's, or on the road. I don't have to search four hard disks. Amazon offers unlimited bandwidth for $55/year.
Jennie does video and I collect music. Our files are big. At 20 megabits, the fastest upstream I can buy from Time Warner, I've spent a month uploading already but have at least a month more to go. (Amazon Drive has problems. The index is fast but everything else is slow, sometimes painfully.)
The 20 megabit up comes with 200 megabits down. I rarely even get close to half the download speed given the limits on the other end. I would be much happier if the upload and download were reversed for now. 50/50 would be better for me than 200/20. Verizon FiOS is advertising the 50/50, which I can't get, and winning customers away from cable.
G.fast switches between upstream and downstream by time and can change the time slice for either. (Time Division) Earlier DSLs allocated frequencies to either upstream or downstream and couldn't change them. First DSL engineer Joe Lechleider realized that interference was effectively reduced with more downstream than upstream. Hence, early systems were asymmetric, the A in ADSL, 7 megabits down and 1 megabit up, moving a total of 8 megabits. Symmetrical systems at the time delivered 25-50% less.
The higher downstream matched the market plans of the first interested telcos. Bell Atlantic intended to sell movies and the codecs of twenty years ago needed much more bandwidth. They needed a system that delivered as much downstream bandwidth as possible.
There once was a dream that the consumer net would be two-way, with people producing more content. It hasn't worked out that way, as YouTube, Netflix and other video streamers have grown to a huge share of net traffic. There have been anomalies but they've been few.
A ten megabit fiber network in Sweden for a while was seeing more traffic upstream than downstream. Google in Kansas City offers a symmetric gigabit as well as massive cloud storage for users. Many subscribers have been moving all their music and video to the cloud, taking advantage of the fast uploads. But generally, the gap between downstream and upstream demand has been growing.
Some of us need the upstream, however. Jennie does video, which means she needs to upload gigabytes frequently. I do web design and am starting to put backups on Amazon's unlimited Cloud Drive, a bargain at $50/year. But the unlimited makes the deal very attractive. We would definitely pay more for fast upstream.
Michael Weissmann reached out to me to make sure I didn't get this wrong. Fast upstream over DSL or cable is so unexpected some people didn't realize what they were seeing.

Ultrafast Broadband Gaining Traction at Consumer Electronics Show
Sckipio Demonstrates 750Mbps Upload Speed Over Twisted Pair
LAS VEGAS, NV- January 05, 2016) - Consumer Electronics Show - Sckipio Technologies, the leader in G.fast, today announced it's demonstrating over 750Mbps of ultrafast broadband upload speeds on existing twisted pair copper telephone wires -- over 100 times faster than most consumers achieve today.
This breakthrough performance will allow telcos worldwide to dramatically improve consumer experience with the many new consumer services and devices being announced at CES. In October of 2015, Sckipio previously demonstrated overall download and upload speeds of over 1.5Gbps by bonding two phone lines together -- a highly attractive solution for operators in North America and Taiwan.
At today's upload speeds, it'd take the average broadband subscriber over five hours to upload a thirty-second full-resolution, GoPro 4K video to YouTube -- the same amount of time it would take to fly from Los Angeles to New York City. With the G.fast solution from Sckipio, consumers could upload the same video in 2.5 minutes -- less time than it would take to brew a cup of coffee.
The ITU standard-compliant G.fast technology utilizes copper wires. The Sckipio solution is perfect for Internet Service Providers trying to bring fiber-like broadband speeds into apartment buildings and the small business market at a fraction of the cost of fiber to the premises.
"Most DSL and cable broadband technologies are unable to provide a higher ratio of upload to download speeds, making it very challenging to deliver next generation consumer services," said David Baum, CEO of Sckipio Technologies. "Since user-generated content has increasingly become important, having fast upload is critical and this is a big advantage of G.fast."
The solution is the world's fastest implementation of G.fast and it helps telcos compete very effectively against cable operators using DOCSIS 3.1.
