100mbps speeds at 70 miles an hour, and even 1gbps speeds

Today in South Korea, Samsung Electronics demonstrated new 4G mobile phone technology to the press. What's most impressive is that Samsung claims 4G can deliver speeds of up to100Mbps, which is already faster than most consumer high-speed Internet access connections.

The demonstration took place on a bus that was traveling roughly 37 miles per hour and streamed media such as high-definition TV and data network access. Samsung claims that this is even possible traveling at speeds of 70 miles per hour. President of Samsung's telecommunications network business division Lee Ki-Tai told reporters that "we hope to drive development and standardization of 4G mobile technology. Successful commercial launch of mobile WiMAX will lead to another success story of 4G communications."

Samsung said that it had invested more than $100 million to develop and push out 4G mobile technology. The company also claimed that 4G will replace the WiMAX standard being supported by Intel. In actuality, Samsung is also a supporter of the WiMAX standard but believes that 4G will succeed WiMAX in global support and longevity.

During the two day demonstration, Samsung also showed off a 1Gbps wireless technology that it is currently researching. The company claimed that the technology in development could be 50 times faster than WiMAX. Samsung noted that while 4G technology was extremely promising, it would not be in wide use until roughly 2010.

So...?

And Docomo has been testing how much faster for how long now?

Old news people, if we're going to show off "demonstrations", please let's ignore those not even keeping up with 6 months or 1 year ago.

Seems to be a terrible habit of Samsung's, this "LOOK AT WORLD FIRST WE DID!" thing, when the Japanese or even fellow Koreans have been doing it since months ago...

So...where do you think Samsung comes from?

Korea. I'm well aware of this, did you even READ the post?

Samsung continually brag about "New" and "Amazing" tech that has been public knowledge since forever... Of course all companies lie, but that they do it in such public and arrogant manners is a little disturbing!

There is a difference between very limited, controlled tests, and more public, "live" tests, which this seems to be. Many technologies are tested in the lab, but then it can take a year or more until it gets to the next stage, as Samsung has done. Many of these technologies never make it out of the labs at all, so I'm giving Samsung a "thumbs up" for now.

FIELD tests since mid-2005?

Find me "the fricking difference", as a great man said.

Meanwhile, if you want evidence of similar blatant lies from Samsung please simply Google "Samsung" and "World's Largest" or "World's Smallest", they do this on a very regular basis, it is known fact within the tech world.

I do not deny their accomplishments, I LOVE what they are doing with LCD and OLED, but sometimes they stretch honesty too far...

I, for one, don't care what Samsung says in hype-building press releases. What I do care about is their vast portfolio of awesome products. I think they've earned the right to be cocky. Besides, you can look at pretty much ANY press release by ANY company or organization and find blatant distortions. The squeaky wheel gets the grease, so the more vocal they are about being a technology leader, the more attention they get, the more sales they get, and their shareholders are happier.

Go Samsung!

I agree quite happily that yes, they have awesome products. As I've said, what they do in LCDs, and look like doing in OLEDs, is unrivalled.

And as such I do not mind a certain degree of "bragging" from them.

What I DO mind, is when, they make a flaccid unimportant press release about trialling pre-existing tech, and it makes front news at a place such as this, perhaps unduly distorting their public image when it should already be well-known.

Perhaps my comments felt too directed at Samsung? I understand and expect bullshit press releases; I expect better than reporting them as unbiased truth from any media, though perhaps this is too much to want from any US organization these days.

Somebody is a Samsung hater...
Samsung break your tv? or are you a Sony Fanboi and ranting because they're not doing so hot?

Either way all you are doing is complaining. Complaints do what?

Exactly what tech that Samsung is working on here is pre-existing? By whom? And when, and where was it shown? A 100Mbs phone is certainly not "pre-existing" tech. Unless you have secret sources perhaps?

Even with my little knowledge on wireless communication, I can tell that Samsung is giving out impressive experiment results. Yes, the news you quoted says that 4G field test has been on for a while, but it does not say wheither the nodes are MOVING IN HIGH SPEED or not.
Remember Doppler effect in high school physics? Yeah, it screws up wireless communication pretty badly. Samsung manages to sustain high data rate on a bus moving at 37 mph -> they are overcoming the Doppler effect.

Here is your "the fricking difference".

hehehe, doppler effect?
dude, if you can even register the doppler shift in electromagnetic waves from a mere 70-100mph velocity difference with standard wifi aparature, you'd probably win a nobel prize. get real.

so... let's get real. Here is an publication from IEEE back in 1997 that mentioned the doppler effect on mobile RF system.
http://ieeexplore.ieee.org/xpls/abs_all.jsp?isnumb...

As all the wifi standards are narrow band wireless communication system, I do truly think that 70-100mph velocity difference matters.

its very easy to calculate the exact doppler shift - velocity difference of 70mph means a little more than 0.00001% shift; with a carrier freqs of 800mhz it is less than 85hz. so you see, the doppler effect by itself would be insignificant.

but your link made me realise, there are other factors to complicate matters. particularly the multiple paths that the signal could take, each with a little different doppler shift, interfering with each other... i guess its this difference in the shifts that the abstract you posted calls "doppler spread".

now you've gotten me curious about the exact extent to which this affects reception

"known fact" is known by you, maybe. But that is not a very detailed rebuttal.

Samsung hasn't been field testing this since mid-2005. It is recently that these tests have been more widespread. But they have been working on it for a while.

It would be nice if the screwy reply order problem was fixed. Attempting to reply to a particular post in any kind of order is impossible. Where you end up seems to be governed solely by chance.

Technology is evolving faster then the adoption rate

By ForumMaster on 8/31/2006 1:26:36 PM , Rating: 2

isn't this kind of quick? i know that samsung like pushing new technology, but 3G hasn't been fully embraced and they're already pushing 4G forward? i do know that as soon as samsung started making DDR2 they pushed for DDR3 and now there is DDR4.

RE: Technology is evolving faster then the adoption rate

By h0kiez on 8/31/2006 1:36:51 PM , Rating: 2

Sort of true...but DDR2 is basically the same as GDDR3. Thus, GDDR4 would be the successor to one of those, and Samsung says the GDDR4 is nearly identical to GDDR3...so I don't think any of them are exactly quantum leaps from one another.

There is no DDR3 or DDR4. The GDDR3 and GDDR4 you see on graphics card are not DDR3 or DDR4. DDR2 is almost the same as GDDR3. GDDR4 improves on GDDR3 and would be basis for future RAM development...not necessarily DDR3.

Actually there is DDR3, its already on Intel and AMD's roadmaps for next year, DDR4 is, as far as I know on the "potential" roadmaps, but not officially decided or announced. DDR3 is not based on GDDR3, GDDR3 is based on DDR3. The reason you see the "G" released first is that grphics cards don't need the testing and qualification and integration with CPU/Chipset that system ram needs.

The difference is location. Sure, in America 3G standard is pretty much non-existant.

However, from what I have read, it's been moderately successful in foreign countries, Japan being one example. A quick Google search stated that the number of 3G subscribers in Japan is already in the 10s of millions, whereas America (if the article I saw was correct) doesn't have a true 3G service out yet.

The whole wireless network issue is yet another where America lags behind some other countries of the world. Perhaps it's just the consumers not wanting the newest though.

whats the holdup

By Lazarus Dark on 8/31/2006 12:29:39 PM , Rating: 3

at first my eyes popped out a 100mbps, but then I saw 2010. Why not sooner? they've had enogh time. I've been wanting high def on demand movies via internet for at least five years. 2010? so slow...

Let's hope it goes well...

Let's learn from the mistakes of 3G. Finalize it fast and implement it fast. Government should stop cashing on those spectrums, and just let telcoms implement 4G immediately. Samsung already demonstrate 4G in Korea as well as Singapore, if I am not mistaken. That's one leap for telecommunication.

driving a bus...

"we hope to drive development and standardization of 4G mobile technology."
ah, so thats why they were in a bus.
and they hope to drive it at 70mph next, eh?
