150 Mbit/s DSL.
surstrmming writes "German company Infineon have released their new QAM

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.
Maybe HE can provide faster nudity...
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.
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.

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).

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!
