Full speed ahead for 802.11ac Gigabit Wi-Fi

Full speed ahead for 802.11ac Gigabit Wi-Fi | cross pond high tech | Scoop.it
Last December customers were peppering wireless LAN vendors with questions about whether to upgrade to the pre-standard-but-certified 802.11ac products flooding the market or hold off until 2015, when more powerful “Wave 2” Gigabit Wifi gear was expected to become prevalent. A year later, even though Wave 2 products have begun trickling into the market, many IT shops seem less preoccupied with Wave 2 and more focused on installing the Wave 1 11ac routers, access points and other products at hand
Philippe J DEWOST's insight:

Time to check for your 802.11ac compatibility. WiFi isn’t about the coverage anymore, it’s about capacity.

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

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 ...

AT&T CEO: We'll piggyback on Google's Fiber rollout plans

AT&T CEO: We'll piggyback on Google's Fiber rollout plans | cross pond high tech | Scoop.it

If Google is allowed to go after specific neighborhoods and homes in Austin, Texas, AT&T says it should be able to snag the same terms and conditions for its own fiber-optic deployment.

 

"I think you are going to see that begin to manifest itself around the United States, and in not just AT&T and Google. You will see others doing this because the demand for really high-speed broadband via gigabit-type fiber-based solutions on a targeted basis is going to be very, very high," Stephenson said.

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

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.

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

"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.

Orange : un réseau FTTH et une Livebox vraiment à 1 Gb/s

Orange : un réseau FTTH et une Livebox vraiment à 1 Gb/s | cross pond high tech | Scoop.it

C'est ce qu'un abonné a d'abord signalé sur Twitter, et ce que nous a ensuite confirmé un porte-parole de l'opérateur. « De plus en plus » d'abonnés à l'offre haut de gamme Livebox Jet Fibre passent ainsi de 500 Mb/s à 1 Gb/s, « automatiquement et progressivement ». Si la totalité des foyers éligibles à la fibre d'Orange sont éligibles aux 500 Mb/s, tous ne peuvent pas bénéficier de 1 Gb/s : « Ni plus, ni moins que chez les autres opérateurs ».

Et contrairement aux box de Free et à certaines de SFR, la Livebox Fibre permet bel et bien de profiter d'un débit brut de 1 Gb/s. Les premiers tests montrent effectivement un débit utile d'un peu plus de 910 Mb/s, une partie de la bande passante étant utilisée pour le fonctionnement du réseau, ce qui est normal. La Freebox quant à elle — à moins d'utiliser le mode bridge et de renoncer aux fonctions routeur et Freebox OS — n'est pas capable de router les paquets à plus de 400 Mb/s. Chez SFR la NB6, qui équipe une partie des clients fibre, limite le débit à 850 Mb/s. La NB6v pour sa part est la plus rapide puisqu'elle atteint 950 Mb/s (on suppose que l'encapsulation utilisée par SFR est un peu moins gourmande que celle utilisé par Orange).

Philippe J DEWOST's insight:

AT&T's expanded 1 Gbps fiber rollout could go head to head with Google

U.S. broadband giant AT&T could roll out 1Gbps fiber-optic service to up to 21 new metropolitan areas, including Atlanta,   Chicago, Los Angeles, San Francisco and San Jose, California, the company said Monday.

 

The company's rollout of its U-verse broadband with GigaPower service will also include television service. AT&T had previously   announced plans to build ultra-fast broadband in Austin and Dallas in Texas and in Raleigh-Durham and Winston-Salem, North   Carolina.

 

The company will work with local leaders and groups to discuss ways to bring the ultra-fast broadband service to communities,   the company said in a press release. Communities that have suitable network facilities, and show the strongest investment   deals, based on anticipated demand and the most receptive policies, will influence the company's selections, AT&T said.

Philippe J DEWOST's insight:

1 Gb/s is the new frontier. Google paved the way and now it's expanding. Sony's network in Tokyo even tops 2Gb/s though I wonder how many users actually have the appropriate Ethernet or WiFi interface to deal with such a throughput.

 

In France Orange is rolling out 500 Mb/s down / 200 Mb/s up which is not too bad. I currently enjoy 300 down / 50 up at home already.

Bell Labs using "noise canceling" to reach fiber optic speed of 400Gbps over nearly 8000 miles

Bell Labs using "noise canceling" to reach fiber optic speed of 400Gbps over nearly 8000 miles | cross pond high tech | Scoop.it

Alcatel-Lucent's Bell Labs has found a way to go that extreme distance by relying on the basic concept behind noise-cancelling headphones. When the researchers send data across two light beams in opposing phases, they can superimpose the signals and neutralize the distortion that would normally occur at long ranges. Such clean output lets Bell Labs ramp up the signal strength and maintain high speeds across whole oceans: its test pushed 400Gbps through 7,954 miles of fiber.

Fighting the capacity crunch, Orange and Alcatel-Lucent set 400 Gbps fiber link live | cross pond high tech | Scoop.it
The link between Paris and Lyon is the first operational deployment of long-distance 400 Gbps wavelength fiber connectivity, with its first tester being France’s educational and research network, Renater.
Philippe J DEWOST's insight:

Fantastic bandwidth increase potential here, as also evidenced by the recent US move towards 1Gb/s FTTH.

This should help us think out of the "100 Mb/s = 35€" french FTTH box IMHO
