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!
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.
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.
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?
Hollywood surrenders. Film at 11.
...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.
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).
NTT DoCoMo's 4G Tests Hit 300Mbps

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?
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.
hey i consider my wife a geek/nerd as she is a conservation/sustainable whatever biologist ... and she would buy peopl emagazin and she is wathcing channel E .......
.... I am embarassed when she buys people magazine in the supermarket ..... it is just soooooo not geeky .... and she does not read slashdot or willing to watch anime with me ...... nor play wideo games .... and i was happy that i married someone with a super geeky carrier ........
...... isn't there a way to geekify your wife ?
.... here in Costa Rica GPRS is experimental for te last 2 years so it is cheap ... but being experimental it is sometimes down or unacceptable slooooooooow ...... and no MMS ...... ... her maybe in 2099 you will be able to watch wideo streams on a phone .. evenmy cable si too slow for streams .... well at least i have good weather unless it is the rainy season ...
my God
nah i go back to watching whatever boring movie she just rented
hmm returning to phones
well i just look at my all-featured EDGE/GPRS/whatever cameraphone and wonder if it is fun to send pictures each other and stuff
