XG.fast DSL does 10Gbps over telephone lines

XG.fast DSL does 10Gbps over telephone lines | cross pond high tech | Scoop.it
From arstechnica.com - October 20, 2016 4:45 AM
Nokia has achieved a connection speed of 5Gbps—about 625MB/sec—over 70 metres of conventional twisted-pair copper telephone wire, and 8Gbps over 30 metres. The trial used a relatively new digital subscriber line (DSL) protocol called XG.fast (aka G.fast2).XG.fast is the probable successor of G.fast, which was successfully trialled in a few countries over the past couple of years and will soon begin to commercially roll out. (In an unusual turn of events, the UK will probably be the first country with G.fast.)Fundamentally, both G.fast and XG.fast are best described as "VDSL on steroids." Basically, while a VDSL2 signal frequency maxes out around 17MHz, G.fast starts at 106MHz (it can be doubled to 212MHz) and XG.fast uses between 350MHz and 500MHz. This means that there's a lot more bandwidth (the original meaning of the word), which in turn can be used for transferring data at higher speeds.
Philippe J DEWOST's insight:
As popular wisdom says though, "your mileage may vary" ... Fast broadband to the home is also pushing the bottleneck to WiFi routers and boxes. Yet this is still an achievement for the old copper wire !

Alcatel-Lucent sees 'major breakthrough' in tech for 1,000Tbps speeds

Alcatel-Lucent sees 'major breakthrough' in tech for 1,000Tbps speeds | cross pond high tech | Scoop.it
From www.zdnet.com - November 24, 2015 1:22 PM

Alcatel-Lucent's research arm, Bell Labs, has announced that ongoing testing of its prototype real-time space-division multiplexed optical multiple-input-multiple-output (MIMO-SDM) system could see the company attain speeds of 1 petabit per second in time for the arrival of 5G and the Internet of Things.

 

In what the company called a "major breakthrough", a trial of the 6x6 real-time MIMO transmission technology in New Jersey saw Bell Labs successfully remove for the first time crosstalk from multiple signals on the fibre supporting the six parallel optical signal paths using real-time processing.

 

"This experiment represents a major breakthrough in the development of future optical transport," Marcus Weldon, CTO of Alcatel-Lucent and president of Bell Labs, said.

"We are at the crossroads of a huge change in communications networks, with the advent of 5G wireless and cloud networking under way. Operators and enterprises alike will see their networks challenged by massive increases in traffic. At Bell Labs, we are continuously innovating to shape the future of communications networks to meet those demands."

The successful experiment used six transmitters and six receivers alongside real-time digital signal processing over coupled fibre stretching 60km in Bell Labs' global headquarters.

Philippe J DEWOST's insight:

The race is certainly not over. Nokia might appreciate.

Over 40 Terabits/s across more than 1800 kilometers : Verizon, NEC claim fiber speed records

From www.telecomasia.net - April 12, 2013 1:58 PM

Verizon and NEC said they have successfully sent the highest-capacity transmissions for regional and long-haul distances over field fiber.

 The two companies said tests showed that by expanding from one band to two bands, the C-band and the L-band, the two firms were able to transmit 40.5 terabits per second for a long-haul distance of more than 1,800 kilometers (1,118 miles) and 54.2 Tb/s over a regional distance of more than 630 kilometers (391 miles), using Verizon’s fiber loop outside Dallas. The achievement was accomplished by tightly packing optical channels in the two bands of the optical fiber spectrum, the two firms added.

How would you call Very Hight BroadBand ? VHBB ? TTHD (Très Très Haut Débit in French) ?

FCC Chief Calls for Gigabit Internet in All 50 States By 2015

FCC Chief Calls for Gigabit Internet in All 50 States By 2015 | cross pond high tech | Scoop.it
From www.cio.com - January 21, 2013 6:17 PM

"There should be at least one community per state with 1Gbps Internet, to drive innovation, Genachowski said..."

 

Cities around the U.S. will have gigabit-speed Internet access by 2015 if the FCC's wishes come true.

 

All 50 states should have at least one community where consumers can get 1Gbps or faster Internet access by 2015, U.S. Federal Communications Commission Chairman Julius Genachowski said on Friday. Speaking at the U.S. Conference of Mayors Winter Meeting in Washington, D.C., he called the new push for fast networks the Gigabit City Challenge.

 

Gigabit-speed Internet access stimulates technology innovation and associated economic growth, Genachowski said.

"The U.S. needs a critical mass of gigabit communities nationwide so that innovators can develop next-generation applications and services that will drive economic growth and global competitiveness," Genachowski said, according to an FCC press release. He cited Google's new network in Kansas City and a fiber network built by a local utility in Chattanooga, Tennessee, where he said Amazon.com and other companies have created more than 3,700 new jobs over the past three years.

Get Ready For 'Super Wi-Fi' To Be A Big Thing In 2013

Get Ready For 'Super Wi-Fi' To Be A Big Thing In 2013 | cross pond high tech | Scoop.it
From www.businessinsider.com - September 4, 2012 9:53 AM

By this time next year, thousands of people will be using a new longer-range kind of Wi-Fi commonly called "super Wi-Fi."


Super Wi-Fi isn't really Wi-Fi, a form of wireless networking which uses unlicensed spectrum. Instead, it's a new kind of wireless network running on unused or underused spectrum known as "white spaces." It's championed by the likes of Google and Microsoft.

AT&T's Project AirGig could be a wireless alternative to fiber

AT&T's Project AirGig could be a wireless alternative to fiber | cross pond high tech | Scoop.it
From www.engadget.com - September 22, 2016 6:27 AM
The project is still in its experimental phase, but AT&T says it's bursting with potential. AirGig's relay stations may sit on top of telephone poles, but it doesn't actually need to tap into the pole's power source -- it doesn't send signals over the lines either, opting instead to regenerate millimeter wave signals from station to station. Because the stations are designed with to use affordable plastic antennas and make use of existing infrastructure, it offers a potential way to bring high-speed connections to new areas without laying down new cable. Not only does that save a ton of money, it also means the new system could be deployed faster.
Philippe J DEWOST's insight:
While europeans break speed records with 1Tb/s on fiber, ATT looks into Wireless Gigabit for rural areas.

The Moon Now Has a Better Internet Connection Than The US Average

The Moon Now Has a Better Internet Connection Than The US Average | cross pond high tech | Scoop.it
From www.geekosystem.com - May 30, 2014 5:05 AM

Called the Lunar Laser Communication Demonstration (LLCD) and constructed by a joint team of NASA and MIT engineers, the set-up consists of four laser transmitters at a ground terminal in New Mexico, which send coded infrared light pulses though four different telescopes and up to a lunar satellite384,633 kilometers out into the depths of space. As a result, we now have a data uplink with the Moon that reaches up to 19.44 Mbps. If you live in the United States, that’s about two and a half times more powerful than your standard 7.4 Mbps.

Philippe J DEWOST's insight:

Well, currently enjoying 50 Mb/s upping and 280 Mb/s downlink. And my ping time is certainly better than the minimal 2,56 seconds. Yet I live closer to the US and in a much more dense area ...

Carriers Prepare for Unicast Pressures

Carriers Prepare for Unicast Pressures | cross pond high tech | Scoop.it
From www.lightreading.com - March 21, 2013 2:10 PM

Unicast traffic might account for a small percentage of current video streams on telecom networks but the volume is set to increase dramatically, affecting IPTV-related network investment decisions during the next five years.

That's the view of two operator executives who addressed industry analysts and the media in London Wednesday morning on the fringes of the TV Connectevent at London's Olympia exhibition halls.

 

Ibrahim Gedeon, the CTO at Canadian operator Telus Corp., and Lukas Fluri, head of Product IT & Devices at Swisscom AG, agreed that unicast video traffic (driven by the uptake of catch-up TV services) would grow from current low levels to somewhere in the region of about 30 percent of total video traffic within the next five years. And that, of course, puts greater pressure on network capacity, planning and management.

 

The shift from broadcast to unicast video streams has already forced Swisscom to invest in greater core network capacity alongside ongoing investment in mobile broadband, fiber-to-the-home and DSL vectoring in its wireless and fixed access networks, "all very capex-intensive projects," noted Fluri.

Philippe J DEWOST's insight:

This is great news for unicast pure players like FairPlayInteractive.tv

UK government and industry heavyweights set up 5G Innovation Centre, want to go one better - Engadget

UK government and industry heavyweights set up 5G Innovation Centre, want to go one better - Engadget | cross pond high tech | Scoop.it
From m.engadget.com - October 10, 2012 3:45 PM
The UK is almost ready to flip the switch on its first LTE network, but it's determined to be at the forefront of the next-generation, setting up a "5G Innovation Centre" at the University of Surrey. The government announced it's putting up £11.6 million (around $18.6 million) in funding, but another £24 million (around $38.5 million) will be coming from an industry group comprising the likes of Huawei, Samsung, Telefonica, Rohde & Schwarz, Fujitsu and others. The money will allow research to go beyond concept and theory, with the aim that all partners work together to develop and standardize 5G technology, which the university has been looking into for a number of years already. They will focus on energy and spectrum efficiency as well as speed, and although it's early days, 10Gbps has been banded around as a per-tower target, translating to roughly 200Mbps for each connection...
