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?"
'Your brand-spankin'-new 3G phone is nearing obsolesence:'
Not in America it ain't.

...that it's a very small island, just put big transmitters on mountantops and you're good to go
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.).
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.
Who comes up with these names...
Assuming the poster is referring to ``variable spreading factor orthogonal frequency code division multiplexing (WSF-OFCDM) downstream technology'', the name describes exactly how the technology works. Without reading a technical paper on the technology, I don't know the exact details, but I know what it is doing and what it isn't doing.

their new variable spreading factor orthogonal frequency code division multiplexing (WSF-OFCDM) downstream technology
This is a lie!
I had nothing to do with this!
(And I don't do variable spreading of my factor. And certainly not in a car going 35 mph.)

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.

That means that they got....let's see....carry the one...
135Mb of data through before the battery ran out.
Pretty good.

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...

how does Japan manage to stay lightyears ahead of everyone else in wireless?
Might have something to do with the fact that they have 130 Million people in an area slightly smaller than california.
Lot less area to provide coverage for. Not to mention 26 million people in Tokyo alone, making it the highest density city on the planet.
.
From what I understand (never been to Japan), everyone wants the best coolest *insert random item here*. People will upgrade their phones and other gadgets every month, and get rid of their old ones.
In the US (live in US so cant say the same about other countries), yes people will buy the latest greatest, but will keep it for years, how many people do you know that have cellphones that are 2-3 years old.
People will only upgrade when their gadgets break, or a new technology comes out they really need. so new phones come out slower, and cheaper (cheap = break easy).
No point in rushing out the newest greatest items when people will allways wait.

More specifically, financial density. Japan is the world's second biggest economy, with an economy roughly half that of the US, or three times bigger than the UK, but with only double the population of the UK. Money is also more equally spread between the rich and poor in Japan. This leads to a relatively high monetary density country-wide, meaning lots of people who can afford high-end services.
This would explain why other densely populated counties, like Bangladesh, aren't riding high on the wagon.. it's because Japan is rich, has wealth more fairly disitributed, and has a dense population. Scandinavia also has its wealth more fairly spread between its citizens, and also boasts some of the world's most impressive mass technologies.
