NTT DoCoMo's 4G Tests Hit 300Mbps 259

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 does Japan manage to stay lightyears ahead of everyone else in wireless?"

    Simple, smaller area to provide coverage = lower cost. That's why in places like South Korea you can get a LOT of bandwith a whole lot cheaper than here (U.S.).

    Japan is small, The US is huge. Converting the entire japanese network is a meager task compared to converting the entire US network, or even in all the major cities in the US.

    because the alternative they have, which is to rewire the humongous buildings that they have in the very limited amount of space available.

    Same story with Chine from a different perspective. Wiring the old buildings for phone communications is not feasible fianncially.

    At the end, when alternative is very expensive, people tend to be more creative than what is expected of them. Can be applied to anything, not only wireless or technology...

    Because Japan is densely populated on a mall landmass, it's not such a logistical nightmare to have almost all the area covered by high end wireless service. It also can offer a quick market turnaround and a stepping stone into the greater world market.

    At least physicists have the decency to choose names like "gluons" instead of "strong nuclear force gauge bosons". Unless I'm in the field, neither "gluons" nor "variable spreading factor orthogonal frequency code division multiplexing" is going to mean that much to me, but "gluons" is a lot easier to say.

    sure it is... just like every other phone you can buy here :(

    Maybe they don't have risk-averse, office-politics-obsessed middle managers more interested in shitting all over other people's careers than actually building something useful?

    Maybe they have found a way to put capital to work employing people and building new products instead of sitting around a table whining that they might fail.

    First it was cars, then electronics, now animation. So Japan is kicking our ass again? Well boo-fuckin-hoo.

    Seriously. Has anyone seen an actual 3G network yet? GSM/GPRS speeds are still like dialup, but with a latency that makes you yearn for your dialup connection. CDMA stuff (like PCS Vision) is faster and has acceptable latency, but still, 100K or so really isn't great. I've heard the term 2.5G thrown around, but wireless internet is still no great shakes as far as I can see.

    Actually, we are waging a cultural battle that we are never going to win. Most of my friends in Tokyo who are in their 20's and still not married still live with their parents. And they average about 60K in income. Stop and think for a second how many toys you could buy for that kind of cash at the expense of still living with your parents. No place to make out with your girlfriend (I know this is slashdot, but work with me on this...), no problem, just go to a love hotel with the waterfall themed room and only pay $30 for 3 hours of sweet loving. Yes, eventually you'll get married and get a place of your own and be back in the poor house, but by then your tired of having the bleeding edge in fashion and tech and are just happy with something that works. No hurt to the economy as there is a generation of youngsters rolling almost their entire bank into having cell phones that double as credit cards/train tickets/PDAs/TVs/Digital Cameras/Radio telescopes. Just imagine if every young american was buying a new cell phone on an average of every 6 to 12 months....the companies would be forced to innovate to give us something better than we bought 6 months ago or lose us to a competitor who say, already is developing wotking 4G technology.

    And which the (minor by comparison) exception of pearl harbor they do not carry a history of sensless genecide.
    You have got to be kidding. Americans are so fucking ignorant about world history it makes me weep.

    This is not true. This is just a prototype - you can easily use rake receivers to combat fading effects (due to non line of sight components)....

    So not true. Japan has far less skyscrapers and tall buildings than say New York. There aren't 30 million people in the Greater Tokyo Area because of skyscrapers, they're there because it's a huge urban sprawl with 5-15 story buildings. For the most part, these are fairly new buildings too (nobody wants to build longlasting buildings for obvious reasons).

    It's not exactly difficult to wire these buildings. In Tokyo, you can get fiber to the home for an insanely low price (on Western standards). Claiming that the need to rewire buildings is an impetus for wireless is clearly invalid in this case.

    Neither is Japan ahead because of the population density. It may be part of it, but take Finland for example. Their population density is about half that of USA, but even they are lightyears ahead in cell phone technology.

    I'll call your bluff. Take the CIA stats for population density in USA [cia.gov] and Finland [cia.gov]. Which one of these two countries is ahead in cellphone technology? Don't ever again try to tell me it's an issue of population density.

    People will only upgrade when their gadgets break, or a new technology comes out they really need.

    My GSM phone is going on 7 years old. I keep it because it is a mobile telephone, which works well and has a standby time of about 3 weeks or talk time of about 8 hours. Until I find a phone I can rely on to keep me contactable all day almost guaranteed or until it breaks, I will keep it.

    I don't ever want to go back to the days of having a mobile that cuts out before the business day is over and I'm nowhere near a power outlet.

    I see friends who have these super expensive mobiles that do-it-all, but don't last a day if they listen to some mp3's. Keep your old phone and buy an iPod!
