150 Mbit/s DSL.

chips, providing 150 Mbit/s data rates over ordinary copper wire." Note that that kinda throughput is at the 1000 feet mark... but the chip can still serve up 4mbps even at 13,000 feet.
I used to drool over the 'next-generation-is-just-around-the-corner' stories, but
;-)
lately I have been having second thoughts.
I live in the middle of Silicon Valley and they can't even serve me DSL better then
190Kbits/sec. No cable modem in my area eiter. It is so painfull, I almost posted this

No really...when will last generations broadband stuff truly be available to the masses
here in the US? Who and how will they fix the last-mile problem if the governament isn't
stimulating this issue?
Same with the phone network. 3G you ask? HAHAHA, not in the mother-of-all-technology
countries, nosir.
Thats pretty awesome, however with some people > 5Km from their CO, they may not get a proper sync rate. I'm, thankfully, very close to my CO, and have a 3mbps line now. Downloading at 350kb/sec is awesome, but after a while the cool-factor wears off. It's handy when Red Hat and other distros of interest are released but otherwise it's an expensive (70 Canuckles a month)toy.
Maybe HE can provide faster nudity...
many intranet connections are less than 1000 ft from the router. so now the chip could be used for intranet connections too. since most people have office phone, they can share the same line for data too and no need to worry about laying lots of ethernet cable. can i get one of those at decent price for my home networking? i have telephone connections in all rooms but no ethernet wires.
Great, now with my fast new DSL, I can have an extra long annoying signature..

These speeds aren't that impressive when considering the normal density of telephone exchanges and typical copper cable runs. It seems that the DSL bandwidth over 2 copper wires has reached the point of not being able to significantly increase the capacity at anything approaching Moore's law. When will we have carriers that value the importance of running fibre to the home and developing high capacity switches to cater for this level of bandwidth? Here in Australia, there is serious consideration for the Natural Gas utilities to provide fibre-in-the-gas-pipe-infrastructure.
As the subject says, 99.9% of the the people out there are limited not by the capability of the line, but by the limits imposed by the service provider.
TODO: Something witty here...
Most people I know who have a choice between DSL and cable modem have gone with cable (myself included). This mostly comes down to the speed difference (although in my case it also had to do with a maddening disconnect problem that Qwest DSL could not seem to solve for me).
If DSL could truly start offering service that is MUCH faster than cable, they might be able to reverse the trend towards cable (67% for cable vs. 28% for DSL according to a recent Pew Internet & American Life Project study.)
VDSL Leaders Announce VDSLPlus: Data Rates Up to 150Mbps and Extended Reach Exceeding 4 KM Using Robust QAM Technology
2003-06-11
Joint news release of Infineon and Metalink
Munich, Germany and Yakum, Israel â" June 11, 2003 â" Addressing the market demand for ever greater reach for VDSL and ever greater bandwidth over a single pair, Infineon Technologies (FSE/NYSE: IFX) and Metalink (Nasdaq: MTLK), today announced they are each developing VDSLPlus, which introduces a fifth-band extension of standard VDSL technology. VDSLPlus will enable service providers to offer scalable DSL services ranging from short range applications at data rates up to 150 Megabits per second (Mbps), to long reach applications that allow for more than 4Mbps rates over distances of 4km (13,200 ft) using the same line-card and Customer Premise Equipment (CPE) designs.
VDSLPlus will use a new frequency âoebandâ above the current 12 MHz limit, as defined by international VDSL standards, to achieve the highest speeds ever reached in data transmission over standard twisted-pair copper wire. The benefits of the extended QAM VDSL technology include:
"Infineon and Metalink continuously work to extend the capabilities of QAM VDSL, each making great strides in advancing the technology. As Service Providers and Carriers have mass deployed and gotten familiar with QAM VDSL over the four years it has been in the market, their demands have grown for increased VDSL bandwidth and reach, while they want QAM to maintain its highly cost effective, scalable deployment model. Metalink and Infineon are committed to collaborating with other industry leaders in extending the open QAM VDSL specifications and definitions to continuously meet this demand while preserving strict compliance to international standards," said Tzvika Shukhman, Chairman and CEO of Metalink.
Metalink and Infineon continue to be committed to teaming with other QAM PHY and system companies to promote VDSLPlus standardization in the various standar-dization bodies and to extend the companiesâ(TM) already proven interoperability to the new technology. The two companies are the only suppliers to have demonstrated fully interoperable, commercially available VDSL products.
" The accelerated market demand for enhanced VDSL drives the cooperation between Metalink and Infineon, especially in Asia Pacific and Japan where QAM VDSL is a huge ongoing success. VDSLPlus is an extension to field-proven QAM-VDSL technology, incorporating enhanced integration levels, higher bandwidth capacity, and greater reach capabilities. With more than two million QAM VDSL lines in service generating revenue for Operators and more than a hundred system vendors who already offer QAM-based VDSL platforms, QAM is accepted as the de-facto line code for VDSL,â said Christian Wolff, Vice President of Infineon's Communications Business Group and General Manager of the Access Business Unit.
QAM VDSL chipsets and systems, supporting the ITU, ETSI, Chinese, and ANSI band allocation plans, provide very high speed data transmission rates over robust, noise-immune QAM links enabling simultaneous video, data, and voice services over single-pair copper wires. The inherent simplicity of the QAM line code is demon-strated in superior cost and power advantages over competing VDSL line codes, yet with QAMâ(TM)s sophisticated features and benefits. These advantages are f
I now have broadband from a small, independent company (that is slowly going under cause of SWB), but I get 4 Mbit down and 500 Kbit up for about half the price of SWB's 1.5 Mbit down w/ 16 Kbit up. I routinely have 350 - 450 KB/s downloads, and they have great service. They would most likely hop on a technology like this so they can keep ahead of the big companies, but they are going under.
Without the little companies, there will never be incentive for the big companies to invest in techonology like this or any other technologies that would improve our online experience.
"BEHOLD, CORN!!" - Dr. Weird, ATHF
Why use this old technology when they can invest in newer technology like fiber to the house and/or Internet2 connectivity?
This is a test. This is a test of the emergency sig system. This has been only a test.
Who cares if it can do 150 Mbit?
Nobody is going to run that kind of pipe out to the CO.

It's not a technical problem.
DMCA, Hollings, Palladium. What might have sounded like paranoia is now common sense.
If I may karma whore for a bit, what is this "QAM" busniess?
QAM stands for "Quadrature Amplitude Modulation" which is a fancy name for a simple concept. Also called "I/Q modulation" it's a way to transmit two data streams over the same carrier signal.
The streams are combined in such a way that they can be separated at the other end by using the two most elegant mathematical theorems of man, sine and cosine. What happens, in basic terms, the streams are at "right angles" to each other in the signal.
Being able to have two carriers worth of data can provide a geometric increase in capacity; this was also the technology that was going to be behind "Stereo AM" radio, but that never made it off the ground (Stero AM would have been cool since it would only have to use one frequency for both left and right channels unlike our current analogue sterophonic FM that uses 2 channels).
Hilary Rosen's speech was about her love of money and her desire to roll around naked in a pile of money.
I'm currently about 5KM or so from my CO. No ADSL available, only Comcast cable modem with their usual bandwidth throttling.
SBC did offer to sell me SDSL: twice the price of their standard ADSL ($80/mo) at 128K (bleah).
How about some devices to make it easy to relay the DSL signals to the edges of the CO's area?
If a chip can give you those great speeds at 4KM, can we at least get reasonable service beyond that?
Design for Use, not Construction!
This is great...but seriously out of reach of most subscribers to even be cost-effective to implement.
Then there are the people like me who live in fiber-fed areas. It doesn't matter how close I am to the CO, but because my copper terminates in a SLIC hut and not on a CO's MDF, I'm SOL.
People in my shoes traditionally have had to use either IDSL-based services (DSL over ISDN carrier for 144k), or get a T1.
I wish I had the coin for a T1, though.

..but for the home user it's impractical until the internet catches up to it. I wonder what'll come along where 150mb becomes a must have?
Anybody read up on the Internet 2? If memory serves, they've been dishing out 100mbs or so. I can't remember what they were doing with that bandwidth, though.
I'm not asking from a cynical perspective. I'm really curious what happens when 150mbs can be served up. The first thing that pops into my mind is setting up a server at home (assuming 150 up as well as down. I can dream!) and remotely accessing it anywhere. Fun stuff. Wish I was more imaginitive tho.

The usual reason it slows down is because their local data .

line to your local CO is over sold
They hook up more ppl than they should to the line to
maximize their profits, it is the same thing AOL did
back in the mid 90's just at a DSL scale vs. dial up
The whole shared bandwidth argument touted by DSL providers
against the cable modem ppl , is just a viable against
the DSL providers
If you abuse the network and over sell it, it is going to
slow down for ppl
You might try another DSL modem, NIC, and PC on the connection,
but if they are the same slower speed then your problem
most likely lies with them over selling the lines

If extra bandwidth is only 10 cents per megabyte, a single user on a 150mbit line could choose to purchase up to $4,860,000.00 per month (plus $324,432.46 federal excise tax and $127,368.32 universal service fee) of additional data services! If only a few percent of all users decide to puchase this much data, there would be a huge potential for revenue growth.
4 millibits per second!!!
Outstanding!
At that rate, this 122 Byte comment would take 67 hours 45 minutes to transfer!

Well, it's great that it can pull down 150Mb/s ... but you've gotta have an empty OC3 to feed it. And if you've got an OC3, might as well kick out the extra cash to run in the extra 300 meters.
The 4km @ 4Mb/s is pretty nice, though.
It's all going to be swept away by Digital Spread Spectrum.

DSL has been in the works for around 10 years now and still doesn't come close to its goal of providing one video bandwidth channel which is short of the goal it should have. The problem here is that it takes forever to roll out a new infrastructure. Its time the leaders of the industry realize it and make sure that the next infrastructure rollout has the latent capacity (if not the electronics at the nodes) to carry the petabaud traffic that we'll be wanting in 50 years (that's about how often we can afford to do this crap). Spending any more time and resources on copper is wasting time.
There is a market today for multiple on demand video channels, voice, and internet over a single service. As a consumer, I'd pay double just for the pleasure of dropping SBC on their !@#. Plan for that, meet that, and don't even waste a breath on anything short of that.
To reiterate, the minimum bandwidth requirement for any new deployments should be enough to serve at least three unshared video channels, 3 voice lines, and very high bandwidth internet service simultaneously with room in the medium for growth into the dedicated petabaud range over the next 50 years. Anything less is causing a delay in progress while filling fatcats pockets with the proceeds from rolling out already obsolete services.

Whining gets you nowhere, and it's just annoying for those of us who actually have a shot at using this technology.
Well, Herr Speedy-Hosen, for 1000 feet, I could just hire Michael Johnson to run across campus in - erm - 30 seconds with - let's see - 700 MB per cd... 150 mbit per sec... um..... (click click click) 1,400 cds on his back and get the same throughput! SO TH... What? Ah. OK - maybe this IS a breakthrough after all. Never mind.
"Win treats sysadmins better than users. Mac treats users better than sysadmins. Linux treats everyone like sysadmins."
Let's stop the whining about lack of high-speed coverage! I have another idea.
Anybody up for pitching in together to build a company to force the last mile. We'll simply bypass the telco and cable companies, put in higher bandwidth than this, charge reasonable fees, and have on-demand video and VOIP as built in services. We'll start with dense neighborhoods and then acquire grants for poor neighborhoods and rural areas. We'll use a shared bandwidth scheme with a minimum speed gurantee. If only 1 user is active, he gets the whole pipe.
It's time to stop the whining about how bad the high bandwidth coverage is and just start making money changing it!
There are enough of us out there (and I'm talking just /.ers) who can cover the technical, financial, and regulatory bases and make this thing happen. Why wait for the bloated telcos and cable companies to build (and own) the new infrastructure. Let's build it ourselves.
