Nokia Says It Can Deliver Internet 1,000x Faster Than Google Fiber (engadget.com)
An anonymous reader writes: Verizon Fios has topped Netflix's speed index for quite some time now with its 500 Mbps up and down internet speeds. When compared to dial-up speeds of about 56 Kbps, Fios is roughly 1000 times faster (since 500 Mbps is equivalent to 500,000 Kbps). Google Fiber on the other hand offers 1 Gbps speeds, but it's not as widely available as Fios as of yet. In a statement made to ZDNet last week, Nokia said it has figured out how to deliver internet that is 2,000 times faster than Verizon Fios, or 1,000 times faster than Google Fiber. Their technique is called Probabilistic Constellation Shaping (PCS), which can deliver 1 Tbps speeds over a fiber connection. "The trial of the novel modulation approach, known as Probabilistic Constellation Shaping (PCS), uses quadrature amplitude modulation (QAM) formats to achieve higher transmission capacity over a given channel to significantly improve the spectral efficiency of optical communications," Nokia explains. "PCS modifies the probability with which constellation points, the alphabet of the transmission, are used. Traditionally, all constellation points are used with the same frequency. PCS cleverly uses constellation points with high amplitude less frequently than those with lesser amplitude to transmit signals that, on average, are more resilient to noise and other impairments. This allows the transmission rate to be tailored to ideally fit the transmission channel, delivering up to 30 percent greater reach." Nokia's demonstration is described as being achieved in "real-world conditions," though there is no timeframe as to when the technology will be deployed in real networks.
Google are actually out there doing it.
Good for backhauls and maybe some DC uses.
Not to the home but maybe to an local hub / node.
10GB e-net stuff is still mostly priced at enterprise levels.
By my count, 500,000 is about 10,000 times more than 56.

While I'm sure getting a terabit to the home would be wonderful, the real-world situation is most people are going to continue to have copper to the home for years/decades due to regulatory capture.
Is the Probabilistic Constellation Shaping concept also applicable to twisted pair/coax copper? Because being able to get some people decent DSL would be a major advance. My parents still can't get 1990's-vintage 200 kbs DSL because in 20 years, AT&T still hasn't run fiber *to their own fucking cabinets*, much less the home.
I know AT&T already has g.fast, but that's one of those things that's mostly only useful for short distances and "demonstrations", the actual real-world speed isn't much better than DSL after so many hundred feet, and it would have required the same AT&T who has refused to spend money on fiber to spend money to upgrade their existing cabinets.
Not a Microsoft company.
Microsoft purchased the "Devices and Services division" of Nokia,
but the rest of Nokia is still Nokia.
TFA doesn't claim Nokia said anything about Google Fiber. All it claims is that the number Nokia's talking about is 1 Tb/s, and that "For comparison on the consumer side, Alphabet's Google Fiber embryonic US fiber-to-the-premises service is offering 1Gbps connections.", so the comparison is being done by ZDNet, not Nokia.
They also say "on the consumer side", so it's somewhat like Caterpillar saying some new haul truck can handle 500 tons and the article reporting on it saying "For comparison, on the consumer side, a Ford F-150 can handle 1 1/2 tons" - it's not as if somebody's going to use one of those big trucks to do residential construction, it's just there to give a sense of scale.
