Terahertz video transfer is foretaste of faster wireless

[epit0me]

yeah i was just thinking "what happens if you break the line of sight?" then he commented on it, but it's still cool - gotta start somewhere, right?

[ActiveStorage]

tesla ftw. i need some freee energy right fukin now

[genewitch]

I think the impressive part is that it's uncompressed video (and sound? couldn't tell from the video) data being transferred. not like an MPEG. The transmitter looked to be really low power, surprisingly (it was tiny!) So hopefully stuff way up in the Thz range will replace our crappy wireless G networks. :-)

[FusionNinjin]

regardless this doesnt prove anything, heck i could stream fullscreen video over 1024x768 32bit coloring over my old wireless internal network, the only times that didnt work was when there was a wall in between, hes standing in the same room...

[shuu7777]

w00t futurama!

[wasnr]

i think you're all missing the point--futurama episodes can now be transmitted magically through the air, wirelessly. this is the greatest invention since Vonage brought us tele-phone service, through our high-speed data lines.

[djsuperstar717]

cant you use fiber optic cables with that?

[Boeserwolf93]

using cable somehow contradicts the wish of transferring wirelessly

[dLimboStick]

So what? They use a higher carrier freq. Big deal. Its limitations are obvious in the vid. Why would we step back in time?

[PIXscotland]

At that frequency the signal is blocked easily by a hand. This simply means it has NO practical use AT ALL in domestic applications. This could be used industrially for line of sight point to point permanent links though. This signal will never go through a wall, ever.

[yoshihobbes]

who really freakin cares, its cool

[supafly377]

wow this seems so cool A TERAHERTZ. But I suppose in the future that will be the norm. Do you remember when back in the day 330 mhz was amazing.

(lol the first video to be transmitted in 1thz is futurama maybe 1 thz = future = futurama

[JakeTiDe]

hmm... first thing I think about high frequencies, is high energy consumption. Imagine laptop with THz WiFi, downloading files from net, at speeds exceeding 30 MB/s, although power consumption is so high, that hour of using so fast connection will use all energy, while 10 times slower connection via normal WiFi is for at least few hours longer. Faster machines needs more energy, more energy needs better batteries, better batteries cost much more than standard ones. Am I correct?

[rashm2k]

Yes but you will be using that large amount of power for a fraction of the time!

[elave16]

yes for the time being, no for the future ... it's good to explore other possibilities like terahertz transmision ... if we stayed with what work's we would have never evovled pass the commodore 64 lol!

[KrissSro]

lol xD

[cemre3]

lol his acent...

"up and adam"

[benjeeqds]

GAAAAR you people are all so dense.

[KyubiFox2]

lol futurama

[rswingman]

1Thz = 1000 Ghz. 300 Ghz is not even a third of 1 Thz. Also, don't confuse hz (a measurement of frequency) with bytes (a measurement of data volume). Terrahertz in this case, refers to the freq of the carrier wave.

Oddly, I recognized the linear amplifier from my CB/Ham days. I'm talking 27-28 Mhz. I never imagined it being compatible with microwave freqs.

[CheorkeeXP]

The Thz range is given from 300Ghz to 3Thz. This is the first step and it is in the lowest of the Thz region.

[newscientistvideo]

CheorkeeXP is right about the frequency range.

Confusingly, the phrase "terahertz frequencies" is used to describe a range of frequencies that include some that are actually below 1 Terahertz. So rswingman is confused, but for good reason; it's a misleading term. I subbed the article myself, and had to check this. It would have been better if they'd been called "Q-rays" or something.

All I can say is, it's not our fault; some researcher named it, and we're all stuck with it. :)

[Elor101]

what the fuck are you talking about

[CheorkeeXP]

again, the Thz range is defined as 300ghz to 3Thz.

Yes we all know technically 1Thz is 1000Ghz, but this is not the case here.

They can call it whatever they want, and annoyingly for us, they have called it the Thz region. Confusing for you I understand. Just rest assured that the Thz region does not have to be equal or greater than 1Thz.

[VyseAcher]

Wow! The world rediscovers RF modulation!

[megalomania345]

Year like the world rediscovers a car which you can drive at 10000 km/h

[ClanRooster]

'1 terabyte of data' was NOT even mentioned in the video ! The video stream was output from a DVD player and transmitted to the TV screen using a 300 Ghz signal.

[FusionNinjin]

fake,how would you suggest he get 1 terabyte of data streamed to the transmitter, i mean, dd3 ram is probebly the fastest ram you can get, and youd need 1 terabyte? hello, he fit all that hardware that can transmit 1 terabyte?

[retepvosnul]

Reading must be a lost art or something. What you see here is a successfull laboratory setup that can utilize the terahertz range. It uses a real world application, hi res video, to demonstrate it's capability. In other words they managed to extract data from the oscilating frequency at the terahertz range wirelessly. also ..bludy tweakers.

[thaspecializt]

If one doesnt watch the video, one doesnt recognise the "300 Ghz"-Term here ;-).

Another piece of german engineering ...

[mokeyterny]

hahha u know as much about electronic as my granny does - at least she knows when to shut up.

[retepvosnul]

You could of course be so polite as to endulge us with exposing this crude misinterpretation of the basic technical ongoings as portrayed here within this video . Please, feel free. Really, I'm sure you have tons of relevant things to say regarding this subject in particulair. From the demeanor in your post I'd might even be persauded to believe you could possibly even be a authority in this particlulair field of science. O, great know it all, spill thy beans for us unknowing simpletons.

[deagle94]

omg,woooooooo

[stuigi99]

These guys are obviously experts in their fields -they're watching futurama!

[Zwaffelen]

terahertz, thats like a wavelength of 3um lol. You will need a solid dish to aim it in a direction.

[agungk]

yes, you may use metallic parabolic reflectors, but you can also use dielectric focusing lenses like the man demonstrated.

[drrogla]

What kind of lenses are that? They focus a RF signal?

[agungk]

dielectric lenses (kind of plastic)

[fraseryt]

I'd like to point out that this is a 'proof of concept' model, and that if/when a commercial model is produced it would be much smaller and have a omni-directional transmitter.

tl;dr: don't knock it, it's a work in progress.

[nmg196]

No - it will ALWAYS be focused uni-directional and will not be able to pass through thick objects like walls or trees. That's a limitation of this frequency of the radio spectrum and not the technology.

[kd1s]

Yep, the shorter the wavelength the more difficulty you have penetrating common things.

This is moving towards the infrared end of the light spectrum. Not very effective for mobile, but rocks for point to point.

[hartnell114]

what kind of man gives a demonstrationin not only a place that could potentially be very busy and constantly interrupted, and also comments on how shoddy the product is overall, most wireless users, going o be honest here, are laptop and mobile phone users, would you like to explain to me how the hell that bulky thing is going to be portable and lightweight, i mean,even in the air this things going to go downhill anytime theres a passing bird! ive been thinking,why havnt you?

[KrAzYkArL18769]

its a proof of concept experiment done at a science lab, its not a product demonstration for some cool new device you can get at Best Buy. i doubt the final technology will be anything remotely similar in size or appearance

[JohnMSawyer]

So, with the lenses, making a tight beam that can be blocked by anything between the transmitter and the receiver, is this pretty much like transmission via light beam, which was demonstrated about a hundred years ago?

[aquamammal]

Science Rules.

[xmailmanbiterx]

FUTURAMA!

[superfisto]

Yay Futurama!

[neotoy]

terahertz is really better suited to fiber optic carrier.
