Australian Researcher Boosts ADSL Speeds
sea_stuart writes "Like your ADSL connection to go 100 times faster? Despite the grim state of Australian mathematics and science, there is still exciting original work being done Down Under. John Papandriopoulos, a Research Fellow with the ARC Special Research Centre for Ultra-Broadband Information Networks (CUBIN) has developed a method to reduce crosstalk interference in ADSL technologies to bring speeds up the theoretical maxima possible. With an Australian Federal election due in a few weeks, and both parties promising improved broadband speeds and access, this is a welcome development, hopefully enabling higher speeds without huge expenses."
I got this story last month.
Damn dial up, I almost had forst post! :(
With more bandwidth, we will need more content, so I guess we can expect a few more repeats.
Wow, I wish this was even close to being an issue in one of our campaigns here in the USA. Can you imagine having an issue like this on the national agenda here?

If his technique can make ADSL work at greater distances from the exchange then he might be on to something. I know people who live in non-urban parts of Australia who are just on the limit of distance to the exchange for ADSL to work.
Doubling that distance could increase the number of homes covered by a factor of four.

We don't need faster local speeds but a faster backbone out of the country. Local speeds are fine. We need better ADSL penetration into the interior as well.
I'm more concerned about the grim state of Aussie servers. It's already starting to slow. I wonder if his algorithms work on Ethernet?

If there's a demand for mathematicians or statisticians then they'll be well paid, and being well paid the profession will attract people which'll push down the cost.

There's a company in Sweden called UpZide Labs (http://www.upzide.com/) that's been working on a technology called VDSL (Vectored DSL) for a few years. This also promises speeds of 100Mb/s using normal copper connections in use right now with normal ADSL.
Faster ADSL in Australia? I can't even get Mobile (Cell) phone coverage. Hell, where I work we don't even have landlines just a fucking public telephone booth. Gotta love Rural Australia :/
First of all, this is a dupe...
But more to the point, doesn't VDSL2 already provide similar speeds?
.: Max Romantschuk
So what ? His grandparents may come from Greece. That does not mean mean he's Greek because his surname sounds greekish ...
First: VDSL is already in active deployment e.g. in Germany (offered in speeds of 25/5 and 50/10 mbit here). Second: VDSL does NOT stand for "Vectored DSL" but for "Very High Speed DSL".
This might explain why.

In Australia we tend to call everyone Australian if they've been here for a few years and have citizenship. In America I'd probably be Irish-American or some such thing, despite the fact I'm five generations out of Ireland. Australians tend to find that pretty weird.
Have you ever been to Australia? Greeks in South Eastern Australia are as common as any other ancestry, you find them everywhere from blue collar labour to business, politics, entertainment and broadband research. Even Australia's most nationalistic rednecks don't see them as anything but normal, white Aussies anymore. Personally, I hear a Greek name and immediately think: Melbourne, because how much useful research has ever been done in Greece? Archimedes lived in Sicily, Pythagorus and Zeno lived in Italy, Thales lived in Turkey and both Ptolomy and Euclid lived in Egypt.

About the kind of VDSL in talk: "UpZide Labs - The leader in Vectored VDSL Technology"
Obviously it is "vectorized", or "vectored".
Anyway, about improving *DSL. Is this even a good idea? It'll just make this crap technology stay and hold fiber back. And I for sure hate my DSL company since I have to pay for the telephone line to get DSL, even though I don't use it. Only one provider here in Sweden (Telia, used to be government institution) are forced to provide DSL without users needing to pay for / use, the telephone line.
Is this just a Swedish problem, or is it common that providers forces you to pay for the telephone line, even though you don't want it, or even though you really can't use it, since what they offer is IP-telephony and not really PSTN?
I really wish I had fiber or ethernet...
One sheep.. Two sheep.. Three sheep..

- 1 Mbps up
My Internet bandwidth in about 7 years time, after Papandriopoulos' technology has spread world-wide:- 140 Mbps down

Some time back, a company called Genesis Europe were going to rollout a VDSL network, what ever became of it I wonder. As for VDSL, this article has something interesting to say about it.
.. claims VMSK achieves spectral efficiencies of 90 bits/sec/Hz or more .. These claims are in direct violation of the mathematical principles of digital communications discovered by Harry Nyquist (1928), Claude Shannon (1948), and others"

In the UK as ADSL gets faster the traffic allocations seem to get even meaner. The prices of ADSL connections remain static, even falling, yet the speed of the connections increase. This is obviously unsustainable and this is why people are complaining that they have an 8MB connection yet only get about 4-6MB download speeds.
There's already 50:1 contention, if the ISPs and BT don't increase the speed of their pipes and add more pipes then the extra speeds accounts for nothing.
"normal, white Aussies"? I know we here are heading back to white australia, but not that far, yet. I'll push my children out of here long before then (and I'll remember to post a message here when I do). For now if you are an Indian doctor (not American Indian doctors, anything American is welcome by the present australian government) think again before you come here. The government may think because you look darker therefore you must be on the dark side. Perhaps science is only dim for Australian politicians who do not know that dark skin is for vitamin D, not for terrorism.
You know what they do to (India) Indians in the Redneck US south?

Sure, if you have to revert to calling Australians Greek in order to boost your sense of national pride, you can call him Greek.

I couldn't find any reason why it shouldn't work for SDSL, is there?
Exactly what we need in Australia is higher performance ADSL links, something like this will be perfect for us to use up our measely 20/40 or maybe even 60gb! monthly download quotas in only a day!
Australia doesn't need faster broaband -- It needs cheaper broadband. The pollys are convinced they need to solve the coverage problem and that's it, but really it's only a small part of the problem. Technology to solve this problem is pretty much already available and just needs installing. The long term problem is getting data in to the country. The cost of getting bytes in to Australia is quite high (we're an isolated island afterall) and no-one is doing anything about this!
It is off topic but you need revision in ancient history. In ancient times every Greek city was independent. This form of city is called today city-state. There were numerous Greek city-states in south Italy and coastal Turkey which were as Greek as Athens was. Actually there were no Italian or Turkish country at all at ancient times. Only Persian (now Iran). Also, after Alexander's campain in Asia and Africa, Egypt came under the control of Greeks and became for many years a Greek cultural center (check wikipedia for the term hellenistic if you are interested to find out more). So it is regarded that Archimedes, Pythagorus, Thales and Ptolomy are Greeks who lived in Greek teritories although these areas do not belong in Greece anymore (I can't think of any country with the same borders after thousands of years).
On the other hand, Dr Papandriopoulos made his research (and probably his entire education) in Australia, so - no matter if his backround is Greek - he is for sure Australian researcher.
And somethning more. Research is carried out in wealthy and large countries because it demands lots of money.There is also research in not-so-wealthy and small countries like Greece but it is more difficult for such countries to produce impressive results.
...there is one MAJOR problem; how can you reduce 'cross-talk' interference in ADSL? The Internets is not a copper wire! IT'S A SERIES OF TUBES.
"Normal, white Australian" was intended to mean normal amongst white Australians i.e. no different to someone with British, Irish or Northern European background, but I don't see why I need to justify myself simply because I said something that under some twisted interpretations could been seen to expose racist tendancies.
Oh, and by the way, where are you planning on heading when if country's immigration changes against your liking? Will you go to America with it's patriot act, to Europe with it's almost zero outside immigration quota, to the middle east where denying the divine word of Mohammed often carries prison sentances, breaking women's dress code is punished corporally and homosexuality is punished by death. Maybe to Africa with its political and racial struggles lead to violence against black africans in the Sudan, political opposition and white farmers in Zimbabwe and pretty much everyone in Liberia and Somalia. How about to Japan where they pretend that Ainu and Okinawans don't exist or to China where every religious movement must register with the state and obey its will? How about Indonesia where they deal with the lawlessness of West Papua by sealing the entire province off, claiming that everything is ok and using diplomatic or military force against anyone who tries to get in or out. Even the traditional havens like Canada and New Zealand have things like Quebecois separatists and cultural tensions between Maoris and whites. Humans hate other humans, it's the way it's always been, you want to hate me and have decided that by using the word "normal" I am a racist and started flaming me. Racisim isn't about immigration policy it's about how we treat our neighbours be they all the same or no two alike. If you are not willing to get along with someone it is possibly a good thing that they be kept from you for their sake as well as yours, I believe that most people are willing to get along but there will always be tension between people who can be grouped apart, such as when the peaceful society of Yogoslavia broke apart into nationalistic chaos. If Australian immigration policy has to sacrifice some idealism in order to prevent that from happening here, I'm not against it.
As for Dr Mohammed Haneef, I don't see how this is related to the subject, but am I to somehow feel outraged that he is back in a middle class suburb of Bangalore with his wife and newborn daughter because Australian inteligence agents think he might be a terrorist? He's not locked in Gitmo being waterboarded without charge and he isn't even being accused of being a terrorist, he just doesn't have a guest worker visa anymore because he's seen as a risk. He is surly more related to his two terrorist cousins than he is to any Greek but that didn't stop you from making the connection.

I know that the hellenic cultural area spread far beyond what is called Greece now, in fact the primary Greek ethnic group who settled Athen came from Ionia in Asia Minor (Turkey) and the last major Greek speaking empire, the Byzantines, had their capital in Constantinople which is also in modern day Turkey. My point was not that these men did not live in Greek cities but they did not live in modern day Greece. It didn't make them or their communities any less Greek but it was still interesting that those scientists which were the first ones I thought of, granted in retrospect I'm suprised I didn't think of Aristotle who lived in Macedonia and Athens. As for ancient Turkey, geographically, you could say that Lydia fitted that general area during the classical period, they were not ethnically turks of course because they lived far to the east at that time. The comment was more meant as an interesting aside than proof of any ignorance of the geo-politicial situation of that period or any deliberate slight upon those Greeks who have not emmigrated to Australia.

Great post. It shows what has been going on in Australia for last ten years or so. Whether it's "right" or "wrong" is not that important. Before moving here, look in the miror. If your skin is not white, wait. Politicians here right now do not like you as much as the sun does. They want votes from people like the original poster, not the sun.
If you want to persist in your mantra that skin colour is the primary determining factor in Australian immigration policy and social attitude you're welcome.
However, if there are dark skinned people reading this, be they African, Indian or pacific islander and have valuable skills to share and an interest in getting involved in Australian culture, please ignore the parent poster who is clearly a jackass. Many Australians would like to equate opposition to illegal immigration and opposition to certain cultural attitudes that promote or tolerate violence as hatred to those with dark skin. This is not true as most dark skinned people are not mistrusted in Australia and most mistrusted people in Australia do not have dark skin. Honestly, I'm pretty certain that if you're black and reading this website you'll quickly be accepted into Australian society and will benefit just as much as the next person from a government policy that keeps undesirables out. If you were considering Australia as a destination before, don't let the scaremongers dissuade you.
