NTT DoCoMo's 4G Tests Hit 300Mbps

Posted by CmdrTaco on 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?"

      Actually this is not funny. The United States is, for the most part, sparsely populated compared to most of Europe and Asia. This is why the U.S. carriers hesitated to adopt GSM in the early 90s, which has a fixed number of supported users/frequency and has a maximum cell size due to being time multiplexed. On the other hand, CDMA is able to create much larger cells at the expense of a higher noise floor (hence less users). It was promised to be better suited to sparsely populated areas, yet still tuneable to suit New York City and etc. Whether or not CDMA IS-95 met those goals is debateable.

      Japan is indeed under less contraints. Their cell sizes are very small meaning the required transmission power is reduced. If anybody ever saw a Japanese PDC phone from 10 years ago, and was blown away at how small it was, this is the explanation.

      Yeah, but when a giant lizard (who shall remain nameless) tears down those transmitters every couple of years and they have to be put back up, thats when you see how resourceful the Japanese truely are.

      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.

    "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.).

  5. WiFi Anyone?? by dukeluke · · Score: 5, Interesting

    After reading this article - it has led me to analyze the benefits of this versus traditional 802.11x and the application of 4G in the broadband arena.

    At a proposed sustained rate of 1G, this technology could revolutionize the Internet as we know it today. And, with more and more bandwidth readily available, there will be better multiplayer games online, as well as streaming on-demand cable-like tv off the Net.

    I understand that the technology is proposed for gadgets such as a phone or wristwatch that can also watch HDTV - but imagine a world where everyone has a video-phone conference & everyone also has a 1G up/down broadband connection :)

    In a word - WOW.

    Part of the reason they are able to stay ahead of everyone else is the density of the country. It is a lot easier to deploy new technologies like this when they don't have to worry about huge land masses like found in China/USA/Russia, and even somewhat in Europe.

    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...

    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.
