Experimental 4G Phone Service Faster Than Cable
JymBrittain writes "NewScientist reports that Japanese researchers have achieved blistering rates of transmission for cell phones that allowed for viewing of 32 high definition video streams, while traveling in an automobile at 20 kilometers per hour. From the article: "Officials from NTT DoCoMo say the phones could receive data at 100 megabits per second on the move and at up to a gigabit per second while static. At this rate, an entire DVD could be downloaded within a minute." These transmission rates were achieved using new experimental methods of multiplexing."
32 simultaneous porn streams?! Oh my! I don't need to be going at 20mph for that..
Death by snoo-snoo!
Wow. But if you think the data rates are amazing, imagine what the cost is going to be!
This won't help out when surfing Slashdotted sites...
Paleotechnologist and connoisseur of pretty shiny things.
20 kilometers per hour!
OMG, that's incredible.
One wonders if it's even feasable to take this sort of technology at some point and use it within the home or for local ISPs. I'd certainly pay extra per month for gigabit wireless.
So, when do we get this for our regular desktop/laptop computers? =S
My UID is prime... is yours?
What happens when you leave the parking lot?
For the metric challenged 20 kmph is about 12 mph.
Somebody else can supply the furlongs per fortnight.
there was an actual service, even 3 years after the announcement, today we would have 3d displays, wifi up to gazillion miles and a linux on every desktop (i.e. "the year of the linux desktop")...
not trying to troll or anything, but I can see how 30 years from now instead of posting "where are my flying cars??" people will post "where is my terabyte internet??"
wait till someone tells them about satellite radio
in-car tv's downfall is and always has been reception quality, go under a bridge or near trees and you will watch static
of course its illegal to watch TV in the front and you can look forward to losing your home the first time someone sues you for crashing into their car while watching TV
how about keeping TV out of cars and leave it in the home, whats next ? TV on your motorbike of course !
if your device has enough memory to hold it and is fast enough cpu-wise to sustain a decent gbit pipe.
:)
Regular consumer pc having drives fast enough to get a dvd in a minute? Good thing we nerds get to the good stuff before anyone else.
At this rate the technology will never reach the USA. Thanks for pointing that out right away jerks.
How does a 7-person democracy cut a pie? Into 4 pieces.
If I left the phone in my pocket while torrenting an ISO to my Powerbook with an 802.11g link, would I be rendered sterile?

...a render farm made up of cellphones.
Neither, there's no f'ing cell receiption between Amarillo and Dallas. Thought that was a math problem huh?!
1. Why do they keep adding all these new features? I just want a plain phone.
Get a Vodafone Simply and go read People magazine instead of slashdot.
2. Yeah, that's great and all, but when do we get this for our laptops?
The same time we get it for our phones. While irda and bluetooth can't handle these kinds of rates, usb, wireless usb or the next generation connection interface will. (4G is still years and years away)
Somehow, I don't think the phones could acheive the same bandwidth if there was 1 million of them withing an area the size of a normal city. There's limited bandwidth on the airwaves. Might be good for broadcasting video streams, but if everyone wants different data, it won't work. Besides, we already had technology to transmit 30 channels of video to handheld viewers 20 years ago.
Anthropic principle: We see the universe the way it is because if it were different we would not be here to see it.
backwater.. the USA. where you too can get a mere 3 mbit/s monodirectional while people in scandanavia and japan get 20 megabits minimum, and will soon have gigabit service to their phones. I would like to personally thank the FCC for fostering the competition necessary to get us here.
VLC FOR MAC IS DYING! IF YOU DEVELOP, PLEASE SAVE IT!!
So, with telcos providing data at 2c per kB, downloading that DVD in less than a minute will cost you $98,000.
Surely it's gotta be cheaper to just buy a helicopter and fly to the video store.
...but it won't save you any money on your car insurance.
And if you intend to watch pr0n on it while driving, please DON'T call Geico. Or anyone else. Call a funeral home and make plans for your arrival there shortly.

For the sake of argument, using a stop/start bit (this is asynchronous, after all) you get 600 megabytes, or roughly 1 CD, not a DVD in a minute.
Still, blisteringly fast-- a DvD in five minutes.
Of course, that's downhill, hurricane at your back, towards a Schwarzchild radius, from a running start. With no errors.

Oh those Japanese! This is yet another innovation from the Japanese. Shall we ever catch up?
I am sick of these optimistic figures (to put it mildly).
It is fine for 1 cellphone to receive 100Mbps.
But how does it scale? Remember, there will be about 10000 users within range of a base. Can the base pump out 1Tbps of data? (Remember, the users could be watching live HD video at the same time).
As if a soccer mom talking on her phone isn't bad enough, now they'll be watching 32 channels of TV at the same time.
I would imagine that this could make raiding a warez operation even harder.
High speed connectivity on the go would be a dream come true for big time movie, music and software pirates.

"Hi. This is my friend, Jack Shit, and you don't know him." - Lord Kano
Seriously I've been saying this for years, it is pointless for companies to waste billions of dollars on fiberopitc i.e. (VERIZON, YAHOO JAPAN, & INTEL), on ultra high-speed internet, via any option but cellular. Everyone is putting all this money into all of these various infrastructures, yet cellular is already there, its already across all of the first world and in due time will have the capability to support broadband thats even faster then today's infrastructure. This article proves this, and proves that these other companies are in trouble, deep trouble because in the end it looks like cellular is the future.
Fast connections are not uncommon and I could certainly have found a place to live with one if that was my only priority. If you're just trying to get a decent place to live, weighing all things, you MAY be able to get 24+ DSL down, 1 up in some places. In a few places you may get a real RJ-45 with a fat pipe backing it up in your home, but please don't make it out as some geek utopia. It isn't. You may be worse off, but I think the difference is quite a bit smaller than you make it out to be.
If 3G penetration in Japan is as extensive as it's generally described to be, I'm more than jealous, though...
The problem with lots of digital radio nets is sharing the bandwidth. WiMAX, for example, promises 155Mbps over several kilometers footprint. But in Manhattan, a 2Km radius includes maybe 1M people most afternoons. That's 155bps, 20 bytes per second, per person. <n>G tech usually has fairly widely spaced towers. Even at 100Mbps, they're going to have to put towers only a few meters apart to blanket public spaces with any traffic at all.
Real mobile broadband isn't going to be addressed until perhaps phased array antennas let us share the same frequency with many physically separated transponders. Then we'll be multiply info capacity in the same radiation bandwidth. There might be some interim solutions with bittorrent-style swarms, which increase available network capacity directly proportionally to the number of nodes crowded into a space. But latency and the possiblity of high simultaneous demand for nonredundant objects make that protocol unsuitable for people's personal phones. 4G research will have juicy fruits. But these research results aren't bringing mobile wrist-TV phones to the masses anytime soon.

As a 3G user that rarely achieves 200kbps out of the originally-hyped 2Mbps, even in the the best-served parts of London, I think at least a 10-fold scaling of expectation-to-promise is in order here.
As pointed out, data prices will have to scale too!

can we just have cell phones that make and take calls PLEASE. Who the hell needs GB on a cell phone? m
$ whatis msft msft: nothing appropriate
It's saturday night for the love of bog get out and do something!
But who the hell watches HDTV on a cell phone? Why is having such huge bandwidth to a cell phone useful? I can see where it would be useful for PCs.
I want a phone to phone to computer adapter once I got that service, only problem is that even firewire 800 would be to slow... maybe phone to gigabit ethernet adapter. Who woulda thought that your phone would beat out your computer on the internet.
NTT DoCoMo's 4G Tests Hit 300Mbps
Posted by CmdrTaco on 06:55 AM June 2nd, 2004
from the and-i-still-can't-get-cable dept.
haunebu writes "'Your brand-spankin'-new 3G phone is nearing obsolesence: NTT DoCoMo reveals the results from a new 4G test system.' says TheFeature. While in a car moving at 30kph, DoCoMo engineers managed a peak throughput of 300Mbps and a sustained transfer rate of 135Mbps with their new variable spreading factor orthogonal frequency code division multiplexing (WSF-OFCDM) downstream technology. Who comes up with these names, and how does Japan manage to stay lightyears ahead of everyone else in wireless?"
How on earth would you pick it up?

Don't worry, it'll never reach North America, regardless of what it's being used for.
It would break the cardinal rule of mobile technology over here, mainly "give them the least service for the most money to maximize profits".

The only thing that uses an RJ-45 is a T1/E1. You must be thinking of an RJ-61, which is what ethernet uses.
But who cares....
1 up? You mean, one MBit? Hell, over here in Germany you usually have to pay a small fortune in order to convince your ISP to give you 0.3. If you can buy the additional upstream at all. Serving slightly big files is a real pain when the other side receives them at a rate only slightly faster than ISDN. And the only SDSL offering I have ever heard of is only interesting to small companies.

I live in the suburbs of a 400 000 inhabitants city in japan in one of the less populated prefectures(.5% of the total).And I have a 100Mbps fiber-to-home access at home for 50 usd a month, And you can believe me 3G services are great and everywhere .

I wonder what shannon would say about this?
In Norway the second largest DSL ISP give me a 8Mb down/1Mb up for about 70$ per motnh, altough the prices drop all the time, so it's finally getting quite good. Even rural areas now usually have access to 4/.75 lines at reasonable rates. And now ADSL2 is picking up speed as well(pun maybe intended if funny). That being said only 90% of the population currently has DSL coverage, and the last 10% might be in for a long wait unless the government steps up and makes DSL coverage mandatory. And we have finally gotten 3G here too so all is well i suppose :) Altough who really needs 3G? I'm never away from a computer long enough for cell phone webaccess to become a necessity, altough if need be GPRS give me the ability to do what I need for free.
"If Pac-Man affected us as kids, we'd be running around in dark rooms, munching pills and listening to electronic music"
2) It heavily depends on the protocol on top of the multiplexing: 3G allows high bandwidth, because a single phone can be served by multiple base stations (=masts). However, as we already saw with GPRS and WAP, if the protocol is bad (voice had more priority than data packets; hand overs between base stations could not treat data connections very well too), the whole service will die (=no more WAP).
3) It heavily depends of the number of cell phones per cell. All these test drives show the optimal case (just remember that 3G promised 384 kBit/s, but if you are in a car, you have only less than 100 kb/s left). Data has (an probabily will still have) less priority than voice calls. So your porn download will be stalling, because your neighbour has phone sex ;-)
4) Who really needs that stuff? My country is one of the no 1 test markets in the world (a target market of 6 Mio people and 5 mobile telephony providers!!), we have a lot of different services, phoning is almost free of charge. Virtually nobody uses 3G now, everybody uses the phone for voice connections and short messages. Only a very small number uses the phone for data connections (btw. also multi-media short messages did not catch on yet).
However
Japan is different. When NTT Docomo get in the market, land line internet access was very expensive. Many people used the phone as primary private internet access. That's one reason for the huge success. (Though I, and also the available surveys about that topic, don't understand, why people in Japan pay that much money for phone screen savers ;-)
DOCSIS 3 will use a channel bonding technique to achieve similiar speeds through coaxial. Essentially by reclaiming analog channel space by converting to all digital systems (I'm beta testing this right now) in the next 3 years that same analog space can be phased out giving back all the waste channel space without needing upgrade the cable system itself to support higher frequencies. What this basically does in layman terms is instead of sending all the data across the same frequency it breaks the data up across multiple frequencies in parallel.
Something to the effect of:
Old
699Mhz 11111111
New
699Mhz 1
689Mhz 1
679Mhz 1
669Mhz 1
659Mhz 1
649Mhz 1
639Mhz 1
629Mhz 1
It probably will take 6mhz, not 10mhz but by allowing some space between the carriers it avoids some noise between them.
Get your Unix fortune now!
Currently, data transmission over mobile phones is priced per packet. There are packages to have less expensive usage, but packages themselves are either expensive or limitative (certain kind of data only, or only given connection points). Imagine how high the price can go if you begin to watch a movie everytime your commuting ! ... and, of course, no P2P downloading either !
Well - I care - because that is totally wrong.
CAT-5 cables which are standard ethernet cables are a RJ-45 Connection.
From Wikipedia:
And as for RJ-61, this quote from wikipedia sums it up best:
Your hair look like poop, Bob! - Wanker.
The problem with 3G here in Japan now is that really bandwidth-hungry applications drain your day traffic limit in minutes, not even hours, while with a packet charge same happens with your wallet. Therefore everybody has a 3G phone but no one actually use its 3G capabilities. I think this is a serious problem should be solved before moving on, otherwise 4G will only do it in seconds and that's all.
http://en.wikipedia.org/wiki/RJ-61
Note the part that says "RJ-61 is unsuitable for use with ethernet." But who cares, right?

Yeah, I used to live in France and they have good DSL offer and you can choose from different ISP providers. And now, a friend of mine upgraded is line to ADLS2+: phone, digital TV, radio and Internet access on the same line.
The good thing overthere is that you can choose your carrier and those carriers put their own DSLAM in the CO. Because of this, there's some competition, and the price is dropping (for the ADSL2+ it's about $45 CAD).
I set up a bunch of laptops at work once and used a Linux live CD to create a mesh network. Why can't cell phones be used for something similar. Maybe 10% of a phones wireless bandwidth could be dedicated to anonymous routing. It'd be encrypted of course.

You are probably on the mark here. What most people don't realize is that business is fundamentally risk adverse except in a bubble where the bandwagon effect seems to overcome that risk adversion. Or at least that is what I've observed over a rather lengthy lifetime. In some ways this resembles the prisoners dilemma in games theory, a fundamental part of current microeconomics.

We need to get Iridium capability into lower-priced handsets. Yes, airtime costs $1.49 per minute, but sometimes you need to get through. This is more useful than 4G, or even 3G. What we have now goes out as soon as you get five miles off the Interstate in hilly rural terrain.
Can I come live with you?
Some how i don't think you would like it, despite the fast Internet connection (Utah was that state that decided to pass a law that mandated all ISP's filter their connections if asked by the customer, threating jail time to those who didn't)
Further more, Provo is the town that is home to BYU the LDS Church run school (i don't think you could really call it a 'school' it really should have it's accreditation revoked for, among other things, it's depressing lack of academic freedom).
Which brings up another point, Provo is ~90% Mormon, I, who am Mormon couldn't stand to live in Orem (just a stones throw from Provo, in the same county) for 6 months (how i survived there i will never know) I couldn't see someone who wasn't Mormon being able to stand it (unless you were in Salt Lake, which has a ever dwindling population of Mormons)
It is best to stay out of Utah County if you are not Mormon, do not be tempted by iProvo or it's Sister project UTOPIA.
What if you have ingress on the line at some of those frequencies you mentioned? Will the modem be smart enough not to use those frequencies until the problem is corrected? Or, will it just keep that band open and attempt to perform CRC correction?
Life is not for the lazy.
Sure, there's still a lot of research in MIMO wireless communication, it's one of the hottest topics, but it's not new or experimental anymore.
most phones only have, say, 32M or so of available space. such an insanely fast connection would be useless if you dont have anywhere to put the data. Everything would have to be streaming content, not download-and-play stuff. Unless Apple's rumored iPod phone is released soon, storage will definately be an issue.
Great. You think people have too many annoying ringtones NOW? Just wait..
Should there be a faster downloads lane??
Too easy. There are 99.4 Furlongs in a kilometer and 336 hours in a fortnight. So 20KM/h is equal to 667,968 Furlongs a fortnight
/. crowd is that the speed of light is 299,792,458 meters per second so we could express 20KM/h as 0.000000000000085313386 C. If we take 100 megabits per second over this distance we can finally, empirically, and for the very first time, get the width of a bit.
Because there are 40 rods in a furlong you could also say this is equal to 53,437,440 rods per month.
More relevent for the
1.85 Zeptometers.
Because we know the constant rods to the hogshead is 40 (thanks Abe) we can work out that it would take 4.93 Litres of petrol to carry 100mbits of data. Based on the current price of petrol in Australia this would cost exactly AUD$6.00
Now if we use Einstein as a basis we get the weight of a bit as being
1.81 Nanograms!
So there we have it, this valuable Japanese research has proven the mass, speed, size and cost of a bit.

When you surf the Internet, the speed is governed on a weakest link basis. It doesn't matter if you have a terabyte per second connection. It will never transfer that fast unless every server that the packets pass through operates at that speed. That's why BitTorrent works so well, because instead of operating on a chain, it operates more like (no pun intended) a web.
Before you die, you see DoubleRing...
I have scientifically proved in a post way below this that the cost is AUD$6.00 ;)

That is well and good, but what about latency ? 3G have abysmall latency, one of the reason customers not very fond of it. Hope 4G would do better...
Oh that wasn't what you were hoping for? Though. The mobile phone companies had a cash cow fluke with SMS and have since been trying to emulate it. They gave us WAP wich was like the internet except without the content, cheapness, user content, freedom, speed, images, a keyboard, a screen. GPRS was the next thing, so it was still like WAP but more expensive. UMTS, yet more expensive.
Oh prices should come down as more people use it. But nobody uses it. Well that is not true there a hundreds of business users but strange as it may sound that is not where the money is. Yeah nice that vending machines operators simply attach a phone to send the usage statistics BUT that delivers maybe a euro a day for a thousands customers. They want the SMS craze to spread to mobile internet but fail to realize that A it is to expensive and B people want the internet, not some horrible crippled portal.

What kind of futuristic phone is it that can sustain a 100mb+ data rate?? My 2.5 ghz desktop computer can't sustain that data rate. Reading this article, my mind immediately conjures up images of deception- theoretical - fine, but this slashdot article says they can do this. What the hell kind of cell phone handles rates higher than my desktop system?
I'm still waiting for cable or dsl in my area. I live in northern los angeles county in southern california and we don't even have cable tv in the area. Nextel is the only cell phone provider we can get service with. We even tried to get ISDN to no avail.
North Korea and China both have better broadband coverage and it's pissing me off. I'm willing to pay a premium for services, but can't get them. T1 is the only option and we can't afford to run the cables the 3 miles required to get to our house.
I think more R&D should be spent on getting areas like mine wired services before they go and develop the next bleeding edge wireless technology on delivering fat band internet that won't ever be available to me.
3g will finaly be available in my area when US comapanies roll out g4 nationwide.

This experiment shows 4G will be kick ass in terms of bandwidth, but unless DoCoMo has plans to develop some revolutionary display technology I can't see myself upgrading from 3G.
Keitai displays are too small for this to be useful in the mobile phone market - but maybe that not what they are aiming for?

Sorry DoCoMo, this is just news grabbing tosh. Lets see how they did this.
The origional trials using OFDM achieved 100Mb/s were achieved by using 100Mhz of bandwidth. Thats 1bit/hz efficiency. Unless they will use n=1 (1 frequency re-used across cells) then they will need a minimum of 4 100Mhz channels. Now then, this 1Gb/s stuff likely uses something better than 1bit/hz say with QAM64. But those highorder modulation schemes require very good receivers and excelent signals with very little noise. This is very hard to do even if your the primary spectrum user as you will get interfearence from neighbouring cells and customers using the network.
In trials is completely meaningless. The trials would have very likely been a single cell and a single customer device (mobile phone or whatever). As soon as they add more customers, cells and therefore interfearence then the whole thing will degrade into a right old mess and they will be unable to achieve these 'blistering' data rates they announce.
Besides that, who has 100Mhz of spectrum spare!?
We aint going to be seeing 100Mb/s to anybodys phones any time soon. It's hard enough getting 1Mb/s to customers 1Km away using tiny CPE with tiny antennas in an office block surrounded by steel, concrete and noise.
P.S.
Yes, I do work for a wireless broadband company.
Was the transmission aerial/basestation moving to follow the car? Why is it relevant?
(I know a few years ago I had a lecture from a telecoms guy who mentioned moving aerials for 3G etc, but I didn't realise they were ready to be used)

100 Mb/s is nice, but how much power are they using?
Mea navis aericumbens anguillis abundat
I live in France and my town has fiber optics..... and yes it is symmetrical so upload and download share the pipe. Price is 30 eur / month, including unlimited VoIP Over here Bandwidth is considered a great business incentive so ADSL 20 MEgs is also very widespread. I think the reason for the competitiveness is the fact that they are 8+ operators that can offer you service at any point on the french territory
These high transfer rates were achieved in perfect conditions with no signal fragmentation by obstacles and other slow-down factors. I am using WI-FI for years now and the latest cards from Zyxel together with Zyxel/Cisco routers are capable of transfering at blistering 50MBit/s. Sure, static, not on move, but problems quicky arise when something gets into the signal and you get 0.5MBit/s or less very quicky. High speed is not a problem (nextgen WIFI will have Gigabit/s also) the real problem is the "line of sight" and signal degradation when it must get around something.. especially at these frequencies.
If they could sustain that spec. in urban environments or inside the building then it would be revolutionary indeed.
Actually, here in Japan you can get an adaptor to connect your cell phone to your laptop, so now it's possible to get internet connectivity from your cell provider. I haven't done it as I can't read the instructions and I'm guessing it'd take a smarter person than me to make it work with my iBook, but I've seen a guy surfing the net while on the train. This isn't the same technology as in the article, but still, it's pretty damn cool. Oh, and I think the internet add on package is about $70 or so (I'm not sure) in addition to the cell plan rate.
The modem can't but frequency hoping is a feature on the CMTS side.
Obviously, this experiment is completely biased. The car was travelling at 20 km/h *towards* the transmitter. That gave the bits a higher relative velocity, allowing a higher bandwidth.
I'd like to see the results for when the car was moving away from the transmitter
In other news, 3 japanese scientists found vaporized inside their car. Eyewitness accounts state it was as if they had been inside a microwave traveling at 20 kph.

Heard these claims before, at lower speeds, but supposedly impressive ones.
The problem is with cellular wireless technology, is that there are dropouts. And TCP/IP deals very poorly with this level of retransmission. With IX technology, I get something like 2400 effective throughput, if it works at all, due to lost packets and such.
I would tend to assume the same will be the case with this wonderful new technology.
I'll *start* to believe these claims, when they can complete a voice call (a fairly low bandwidth application) without dropouts and dropped calls.
Love many, trust a few, do harm to none.
...a Beowulf cluster of them!
isn't there a way to geekify your wife ?
Isn't there a way to English-ise your post?
PS. Your full stop key seems to be sticking.

I couldn't think of a sig.
