Aussie Telcos Consider 3G For Last Mile
Mattygfunk writes "Whirlpool reports Aussie telco R&D labs are scrambling to transform 3G mobile networks into last mile solutions rivaling the best wired broadband networks, as telcos come to grips with lack of consumer interest in 3G mobile services and a likelihood of no payback on their multi-billion dollar investments in the spectrum."
fp yaaaaaaayyyy!
wow, finally an affordable application. in europe, 3G almost ruined a major player in the telco market, and severely damaged the financial situation of the German Telekom, after the govt made some 60 billion EUR.
(Oh, as a small remark.. German Telekom's shares are in public hands.. )
yes. yes it is.

Sounds like a stroke of genius. A profitable 3G service, and a cheaper way to connect remote areas. Consumers also benefit. It just has to be technically sound. Any info on this?
Finaly the telcos have realized what 3G is, i.e. a broadband packet based data network. 2G is already adequite for talking, so 3G must offer good data transfer solutions. It may be files, it may be movies, or any other data, but not soley speach. With the suggested rates for the Swedish 3G networks I doubt that this will get a proper breakthrough, but still, it is cheaper and faster than my crappy 9600 GSM transfers.
Will we riding elephants into Fort Knox and steal all their gold? That's the dumbest thing I've ever heard.
Apparently, they're working on a system to reduce undesirable field harmonics, which is part of what is causing the delay.
Try not. Do or do not, there is no try.

why is there impetus to do this last mile bullshit (eg supporting the minority of people out in the boondocks, east/west bumfucks....), and consistently not enough impetus for other similar tech companies to support linux (another minority).

The last mile has been a stumbling block for telcos for about two decades, now. Available silicon can easily handle fibre to the curb, but getting it in already existing buildings has been a problem.
The ISDN suffered from unknown physical plant characteristics - stubs, splitting pairs, and other analogue phone cruft seriously debilitated ISDN acceptance. ADSL leapfrogged the ISDN performance by learning from the mistakes in the ISDN development/deployment.
Hopefully, this repurposing of technology may be just the boost that an ailing telecommunucations industry needs. The hardware portion of the high-tech sector has suffered an abundance of losses after the dot-com meltdown.
This is progress?
Please fuck off and die in a corner. Now. You are a dumb ass, you do not know what you are doing, and you deserve to be beaten with a wet towel within an inch of your life. You are human scum, and are not fit to drink my piss. In short, reply to this post to undo your fucktard moderation, and apoligise for your stupidity.

... the green mile instead of the red mile of no coverage? :)
This may be totally off base, but do any of you Teleco people out there know how many users can get access on a single 3G cell? might this be significantly less people that are within that cell (and wanted access), not only within a city, but in the suburbs too?
If you look at the GSM coverage map of China you will see that it has a large coverage for country so large. From what I undestand the reason for this, which is along the lines of the last mile, is that China did not have any cabled phone network covering that area to start with. Since it was going to cost them as much to wire such a large area and that mobile phones were growing in popularity they decided to go the wireless approach.
The reason I bring the story up, is because once you are in a rural area it becomes increasingly more expensive to connect to homes. The problem is that you get less inhabitants per length of telephone cable, thus making it extremely more expensive short and long term. The long term cost is the inspection of such a coverage of phone lines. The wireless approach allows a much larger area to be covered, and it ends up being cheaper as there is there are less inspection points. It also provides the advantage that the phone company also gets money from visitors to the area and not just the inhabitants. Additionaly, for a farmer, this is great as it allows him/her to phone home when they are somewhere in the middle of their land. This sort of solution could be easily applied to other countries with the last 100 miles problem, not just the last mile.
The only question I ask myself, is whether there are any solutions for solar powered transmission towers?

I'm glad to see someone filling in step 3 at last.

Nice work Whirlpool, getting mentioned on Slashdot.
Simon and Dan should be getting a nice fat brown paper bag from Telstra this month.
The only 3G system I know about is the European UMTS system, whose air interface operates on WCDMA (the same technology as the American system, which I believe is imaginatively called WCDMA).
This system is particularly well known for being resistant to interference. The original CDMA (Code Division Multiple Access - the W stands for Wideband) system was originally developed by the American military to provide resistance to jamming.
The key characteristic of WCDMA is that each handset signal is spread across a wide chunk of the spectrum (around 1.9 GHz in UMTS), by applying a code which is chosen to render the signal orthogonal to those of the other handsets. Applying the code at the other end to retrieve the original narrow-band signal has the beneficial side-effect of spreading any narrow-band interference across the original broad area of the spectrum, thus reducing its intensity. To effectively jam the system would involve swamping the entire UMTS spectrum, which would take a massive amount of power.
As for red lights causing interference in the ~2GHz spectrum - well, that's just plain silly.
Amusing troll, though.
Since 3G seems to be offering higher speeds, will the telco(s) introduce the service at low prices, only to win customers, garner major share of the market, only to raise prices afterwards (price increase follows bandwidth increase; "gotta pay recoup the cost of 3G license")? How are they coping with potential interference issues? What *is* the range of 3G anyway?
Have EVDO, will travel.
Some clues that the parent message is crap:
- it talks about red lights causing interference, even though 3G is far from 'immediately below infrared'...
- (real clue) talks about ultrasonic devices causing interference with 3G phones. How one earth can *sound* interfere with *electromagnetic radiation*???
The journalist who wrote the article seems to be assuming there will be no payback at all from 3G, in its UMTS or CDMA2000 incarnations, to make a more exciting story. Some of the developments discussed aren't really competing in the same market as 3G in any case, e.g. the Arraycomm technology is mainly for fixed wireless last-mile access, and doesn't have much to do with 3G. The Flarion flash-OFDM approach is interesting, though.
While it may take a lot longer to get a payback than people planned, it's mainly a question of pricing and services. The real issue is delivering, at reasonable price points, services that are of interest, e.g. multimedia messaging (zap a photo to your friends/family), location-based services (where's the closest garage/ATM, and how do I get there?), multiplayer gaming (already happening with text messaging, one game lets you zap combatants who are in the same part of the physical world as you are), and much more. An open market for 3G services is critical, the idea being that anyone with a bright idea can put together their own service.
Of course, it doesn't make such a good story if telcos aren't 'scrambling' to fix 3G - in any case, these are all post-3G developments and will be competing with next-generation WiFi as well.
Someone tell me again. Why do I want a 3g enabled phone ?
http://nomoneydownnews.com/
At AU$0.20/Mb for anything over the base plan, data costs are what's keeping the internet expensive here. The current pricepoint is AU$80-90/month with a 3Gb cap. It doesn't matter what the delivery medium is used to deliver the data, that cost sets a lower limit for any pricing scheme.
Cable is severely restricted to the highest areas of population density in the south-east of the country, ADSL is available in a high percentage of exchanges(both metropolitan and regional), and satellite is used for those areas where copper doesn't reach and can afford it($$$$$).
A 3G infrastructure depends on a good underlying data network - which basically describes ADSL(plus ISDN, ATM, etc).
As far as I can see, the areas which have that infrastructure, but where 3G is the only solution are extremely limited. Add that to the very limited market of high-speed-mobile-data users, and you have a solution which has an extremely small number of users for a high development and setup/intrastructure cost.
I doubt it will be a competitive or affrodable "last mile" solution for the forseeable future, outside of a few PR "success stories".
... I don't think it'll be Telstra doing it. By the looks of it, the Australian Federal Government is going to sell Telstra whether or not it meets its 'bush coverage and standards' requirements (they'll fudge the figures to make it look like it has passed). A privatised Telstra will have no interest in the bush.
Over the next 12 months, Australia (or at least the main cities) is going to see many 802.11b ISPs set up shop. With Australia's low population density (making it expensive to have cables running to every home) and Telstra's reluctance to provide even semi-decent infrastructure, I think this sort of thing will be the future of Australian telecommunications.
In the end, this should be a good thing, since competition will be greater. Compared to a cable-based (telephone, fibre optic, etc.) market, there are far fewer barriers to enter a wireless market (the hardest part is getting a spectrum license). Scores of smaller companies will enter, and we will no longer be as subject to a predatory, uncompetitive monopolist (read: Telstra) as we are now. Only time will tell if that situation will last, though.
I'm pinning my hopes on ultrawide broadband (UWB) communications. Bob Cringely wrote earlier this year that it has the potential to be simultaneously ultra-fast, secure and frequency-neutral (i.e. since it uses the whole spectrum, a virtually unlimited number of UWB signals can be running concurrently). The only problem is the range (about 1km, I believe), but 802.11b has this problem, too.

It's obvious that doing the last mile wireless is going to be cheaper than via copper. What baffles me though, is why making calls on my mobile is so much more expensive than a landline when the implementation/maintenance of wireless networks is so much cheaper than copper or fibre. It costs far less to stick a mast up than to start digging the road up.
Like tinyurl, but one letter less! http://qurl.co.uk/
I would settle for them just getting enough bloody ADSL ports in my exchange. Telstra - Grrr....
Zilch
bandwidth per cell is 388,800kbps
resulting in connection speeds of
2000 kbps for 194 subs
384 kbps for 1013 subs
144 kbps for 2700 subs
64 kbps per 6075 subs
Note cell size is > 1Km but I don't have a figure for max cell size.
Source was from a industry report from an investment house.
384Kbps would probably be the most cost efficient and marketable solution giving a similar user experience as ADSL. However cost per Kbs will be hard to get as low as the monthly connection charges and unlimited connection time we see in most ADSL contracts these days.
Still, any to get money back into telco's cant be bad for the industry as a whole.
If you get modded down for a first post... What do you get for a last post?
I was at a conference with a guy from Qualcomm the other day, talking about their CDMA-450 technology, which is basically their CDMA-2000, only operating on the 450MHz band (or maybe 400). The NMT-450 operators in Russia are looking at this as a way of upgrading their networks.
I said that I thought this lacked the critical mass, and the momentum to really compete with GSM 2.5G as a mobile voice/data solution, particularly when you look at how ghastly the handsets are for CDMA450. He said that even so, there is a use for CDMA 450 as a fixed wireless technology.
This makes a lot of sense, because laying cable in urban Russia is a bureaucratic nightmare, not to mention the fact that your competitors may control the ducts that you want to use. Even when you can lay cable, it's much more fun building a wireless link in a climate like ours. Actually my last mile in my apartment at home is wireless (point to point microwave, rather than cellular) and I'm very happy with it. And there is a real shortage of fixed lines in Moscow - one of my colleagues had to wait two years for a line to be installed by the public operator. I was told four years when I asked.
The other thing that I heard at the same conference was that in those areas where the license payment was sensible, 3G would be used to build extra capacity in the wireless network, on the assumption that there are quadra-mode (?tetra-mode) handsets to work on all 3 GSM standards, and W-CDMA. I've seen mention of these handsets already, although given how long it's taken with 2.5G, I'm not holding my breath.
Actually, ArrayComm's I-Burst technology is far more than a fixed last-mile solution. The setup they're currently testing in Sydney is not the first deployement of this technology, but it is a first for Australia where wide-ranging, wireless broadband access is prettymuch non-existant.
I-Burst, at least in Australia, is focused on giving city areas (and perhaps suburban areas), pervasive, roaming wireless Internet access for mobile devices across every major city in the country. And doing it at 1Mbps per connection.
For more information, see this article: http://www.atomicmpc.com.au/iburst.asp

A little company by the name of ArrayComm is currently testing a technology they call I-Burst here in Sydney. Basically, it (should) offer pervasive, roaming wireless internet access across every major city in the country, at 1Mbps per user.
What does this mean? Well, it means that if you've got I-Burst capable NIC's, you'll have a 1Mbps Internet connection at any point across all our major cities (as long as you're not moving too fast) on your laptop, PDA or even your phone (assuming there is phones to take advantage of the tech - doubtful perhaps).
This is beyond what any of the 3G's (W-CDMA, CDMA2000 etc) can offer. The only reason Australian telco's are pimping 3G is because they all spent small fortunes purchasing spectrum to run it on. Considering that these 3G solutions are a long way off, and that we should have a working commercial I-Burst service here in Oz sometime next year, 3G may just die a very quick death.
We conducted an in-depth breakdown of the technology behind I-Burst, including the special directional antennas that make it possible. You can check it out here if you're interested.

When the Europeans were deciding what their 3G telco standards would be, there was a division between Siemens (who wanted to use a Time Division Duplexing System called TD-CDMA) and Nokia and Ericsson (who wanted to use an Frequency Division Duplexing system called W-CDMA). Rather than choosing a winner, the European Telecommunications Standards Institude (ETSI) adopted both standards, and technically UMTS supports both, although W-CDMA has got all the publicity. Spectrum bands were allocated for both, paired (for W-CDMA) and unpaired (for TD-CDMA). In Europe, telcos are required to use these standards, but there certainly have been allocations of unpaired spectrum. Australia decided to auction the same spectrum bands that were auctioned in Europe, but put no restrictions on the technology they were used for. 3G licences were sold in Australia for not much money, as the number of licences and number of players were the same. Arraycom bought some unpaired spectrum for not much money, and always said that it would use the spectrum for its i-Burst technology. This is now happening. (The article is false when it said that Australia uniquely allocated unpaired spectrum. Most of the world did. Australia merely put uncommonly few restrictions on its use. This was not unique either, as other countries (eg New Zealand) did the same.
I don't think i-Bust is technically '3G', but it does use '3G' spectrum.

I remember first seeing the new G3s at a CompUSA several years ago. The blue and white boxes with the easy-opening side door... loved 'em.
why setup tens of thousands, if not hundreds, when you can get broadband internet via satellite today? With such short range 3G repeaters, its senseless to do such a thing. no?
It was recently revealed that nine per cent of connections (affecting over one million customers) are supplied by using pair-gain technology to provide multiple virtual telephone lines over one physical copper line. These virtual lines can not be used for broadband internet services such as ADSL.
If "third-generation" wireless technology can be used to provide the "last mile" of the connection (instead of relying on copper wires), this means ADSL can possibly be provided to the substantial number of customers whose telephone lines are pair-gain. For most of these customers, the only high speed internet access option previously available to them was satellite internet, which (as you said previously) is well beyond most people's budgets, and offers none of the benefits of ADSL connectivity.
