Europe Is Testing 12.5 Gbps Wireless
Lorien_the_first_one brings word that in Europe, a breakthrough for post-4G communications has been announced. A public-private consortium known as IPHOBAC has been developing new communications technology that is near commercialization now. Quoting: "With much of the mobile world yet to migrate to 3G mobile communications, let alone 4G, European researchers are already working on a new technology able to deliver data wirelessly up to 12.5Gb/s. The technology — known as 'millimeter-wave' or microwave photonics — has commercial applications not just in telecommunications (access and in-house networks) but also in instrumentation, radar, security, radio astronomy and other fields."
Im already using it. Its awesome.
When we look at how far behind the American wireless industry is compared to the overseas systems, it's not always correct to simply look at the current status. It's much more important to look at the growth over time, because it is only when you do that do you realize that the American system is keeping pace with European and Asian cellular systems.
Yes, at any particular moment in time the American system may seem far behind, but at some point we do upgrade to the latest and greatest. It just takes a lot more time to decide which version of the latest and greatest we will implement.
So it's much more like taking an elevator to go from one floor to another here in the US. We don't bother with every individual step in between and we get to the same place as the stair-climbers eventually too.
At 30-300 Ghz wireless toasts you!

Not if there is a wall between you and the transmitter though.

and how many of those radiowaves are going to fry our brains ? let me see: ...
- 10 thousands satellites beaming down their TV programmes and GPS coordinates
- 1 thousand TV stations beaming up their programmes (that's very high power)
- 500 millions of cordless phone handsets (frequencies anyone ?)
- 100 millions cordless keyboards and mice (ranging from 40MHz to 2.4GHz)
- 2 billions cellphones and millions of related cellular-comms-towers
- billions of wi-fi connections from portable phones, laptops, VoIP,
- billions of bluetooth-enabled devices
- brand new wireless video devices...
bar the obvious tinfoil jokes, we are going to use a new excuse for calling sick, like "my brain is upset this morning, it must be the new access point that I installed yesterday... sorry, you'll have to cover for me until I finish restoring my brain backup from yest#%@ - what is this email that I sent to myself with a password for a new access point ?"
Can I put a spell on those who can't spell?
Your wheels are loose and they're losing their grip, good you're there.
They'll bolt Siebel onto it and turn it into a dog's breakfast like Telstra here in Australia with NextG!
"Smooth move, Ex-Lax!"
Take the stairs? Take the elevator?
No: Open the door. Smell the cheese.
They'll ruin it by bolting Siebel onto it like Telstra here in Australia with NextG!
4G is a mobile solution where the signal is radiated every direction and cells get blanketed by signals that are useful to mobile devices. Millimeter wave is a point-to-point technology that requires a clear line of sight and should be compared to free space optic laser solutions. You so much as block the beam with a tree branch and it doesn't work. Can we try to get some quality reporting on slashdot? We have plenty of experts in this community and headlines like these need to get slapped down. We don't need another clueless USA bashing headline.
12.5Gbps which means 1.5625GBps and the data transfer limits we have in the states here, it will take 3.2 seconds to be in overage-city.
Hmmm...isn't that faster than a Porsche's or Ferrari's 0 to 60 speed?
[sarcasm]The good thing is....it'll be at least 5 years since they have it in Europe until we have it here[/sarcasm]
Land line went years ago. Fiber will be next together with the 1Gbps wired LAN and everything hanging off it - especially the not so green power adapters, quaint WAPs, Switches, and Routers.
Imagine no more ISPs. Netflix can stop throttling. Computers only need RAM and boot from the cloud.
Will my 4G Google phone need a small power station or will a standard adapter do?

These systems typically have short range in air and thus require many antennas closely spaced. The consequence is that distances are smaller and therefore, due to the inverse square law, the power needed at each antenna is much smaller and the average power in the environment will be much smaller.
It's not just energy, but resonance as well. High energy photons destroy your DNA and cells by brute force. Lower frequency photons do it by resonating with your DNA and cells and shaking them to bits. It's the reason why a microwave oven is tuned to 2.4GHz, as that is the frequency at which water molecules, including those in your body, resonate.
welcome our new 12.5Gbps brain tumor inducing overlords
actually I am happy to see you, however that is in fact a banana in my pocket.
The article is comparing 4G performance at 150 Mbps using only 20 MHz of spectrum to to millimeter wave technology which uses tens of GHz for line-of-sight application for multi gigabit links. Then it suggest that the rest of the world is lagging because of this bogus comparison. OK, maybe it's not just US bashing, but it's bashing the rest of the world.
the correct link is http://www.ist-iphobac.org/, not http://www.iphobac-survey.org/
The comparison with 3G/4G systems is misleading, as these terms denote wide-area cellular telephone networks. Our cellular links are mobile, work over long ranges, and do not require a line-of-sight path from transmitter to receiver. 60 GHz wireless links, by comparison, typically require highly directive antennas, ie. the transmitter radiates energy directly at the receiver in a narrow beam. This makes it more suitable for fixed point link, rather than mobile, at this stage of development. Also, 60 GHz wireless signals are highly attenuated as they pass through solid objects, hence the need for a line-of-sight path. So, while its true mm-wave communications offers unparalleled wireless data rates, the comparison with cellular networks is not necessarily a good one.
One reasons the 60ghz(5mm) mentioned in TFA is so great is that it won't make it from the living room into the bedroom so you don't get interference when you use it to go from the ps3 to the wall mounted flatscreen.
1mm(300ghz) is well into the water absorption band, to get out of it you'd need to get up around to 10 *micro*meter wave lengths. EHF for cellphones would require towers all over the place, the range wouldn't even be as good as wifi unless you jacked the power high enough that it would scare me to use, and even then I don't see it being any farther than a block given a clear LOS.
Incidentally 3mm (100ghz) wavelength is what that "skin on fire" ray uses.
refactor the law, its bloated, confusing and unmaintainable.
This is great! I'll take the money I'm earning from La Casa Nostre Pizza Delivery and put it towards a suit that will let me stay online at all times. I'll be able to record and blog /everything/!
This technology could drive all the nails in the coffin lid for cable TV. At these download speeds one could download all of the programs for all of these channels in a minute or two. The only reason for further contact that day would be news updates. Of course we will need some type of hard drive arrangement that can record 12.5Gps..
First of all, New technologies = new techno waste.
Second, will the new technologies be more environment friendly for production and disposal?
What about energy consumption?
And finally, do the pros surpass cons?
Maybe Computers will never be as intelligent as Humans.

I'm fairly pro-market, but it's easy to ruin things with simple dogma. A lot of business needs to be able to assume basic things are working to operate. If you spend all your time wrangling about sewer hookups for to your office and your power company is an unregulated free-market utility that can choose not to do business with you if you upset their TOS, you spend all your time on overhead and little time on business. The internet these days is basically a utility: if you want it to spur other economic development, businesses and entrepreneurs need to be able to assume it'll be there as a boring, reliable transit method that they don't have to spend more time worrying about. This is basically incompatible with the infrastructure operators, especially in areas where they're local monopolies or oligopolies, trying to maximize profit.
More generally, and to simplify a bit there are two ways of operating in a market economy. One, you can produce a product or service that you think people will willingly pay money for, and then offer it for purchase in the marketplace. Two, you can attempt to gain control over some aspect of the marketplace itself, putting yourself in a position where you can skim some of the money off as it goes by, because people have no choice but to deal with you. The first is the good side of capitalism: entrepreneurs and individual freedom. The second is the bad side: monopolists, market manipulation, and so on.

One of the boundary conditions of internet speed is the size of the material being sent over the wireless network. If all you have is small sound files, then you'll need to be sending over years of music to fully use the 12.5 Gbps. The usefulness of internet speed increases only logarithmically. There is almost as much use for 1000000 Gbps as 100 Gbps. Only a small portion of the people actually using the internet would see any difference between the 1000000 and 100 Gbps. Once you hit the critical value, which is like a few Gbps, most of the people on the world would be satisfied.
Humans are the ultimate boundary conditions. We can only read so much and listen to so much in so much detail and see so many pixels. The best that the data can do is accurately represent these. Once the representation becomes so accurate that adding a few more Gb's of information would not allow a human to see the improvement of the file, then we hit the limit.
Another major limit is time. We can only hope to live up to around 100 years old. Downloading 120 years worth of music would be meaningless then. There is a limit to everything and just increasing the wireless speed past the critical limit is almost useless.
"The technology (...) has commercial applications not just in telecommunications"
I am quite sure it should be useful for cooking.
Is anyone selling radiation hats?
Editors, please be a bit more sensitive. There is no country "Europe", and most of us on the continent Europe do not want it to become a country. :)
We are only stuck with some assholes that we did not vote for, that created a "government" that we can't really vote for, and that we explicitly can't vote not to exist in the first place.
Americans who were stuck with an asshole President, should understand this.
So don't say "Europe", as if it were a single country. It's like calling North-America a country, and thereby saying that the USA, Mexico and Canada are one single entity. You would not like that, would you? Well, we neither.
Just name the country of the company, event or person. And use "Europe" only to describe things that relate to Germans, French, British, Russians, and so on, in the same manner, thereby being a continent-related issue.
Thank you for being solidary, until we got rid of our oppressive governments ourselves. :)
Any sufficiently advanced intelligence is indistinguishable from stupidity.
You mean the prices where you live?
Well, we got better prices. Partially because the EU bureaucrats made monopolies mostly a thing of the past (except for the owner of the last mile, who still has a monopoly, for which Germany actively has to pay fines).
(I know that this is not yet totally true for other things like gas/power yet. But for mobile phones, it worked out pretty well so far. We can get nearly the latest phones including a 20 euro a month plan, with a flat rate, and actually get 200 euro or more payed up-front, when we make the contract! Now that is a good deal! ^^)

Trivial physical chemistry, at least as you're presenting it, is not terribly good at predicting the effect of nonionizing radiation on enzyme kinetics, evidently. It's quite well established that low-frequency EM can interrupt melatonin synthesis (medline, bubba) and alteration of enzyme kinetics is at least one mechanism which looks viable for detection of / interference by low-energy radiation. I've also read some speculation on coupling to excitable membranes but I'm not sure I find that credible.
... alteration of enzyme kinetics ... looks viable for detection of / interference by low-energy radiation. ... [there's] speculation on coupling to excitable membranes ...
Folding might be an issue, too, where a short-term exposure could have long-term effect.
= = = =
That said: The move to everything-spread-spectrum would help to reduce the ability of microwave photons to gang up by resonance, potentially increasing the threshold of exposure necessary for an effect (though simultaneously eliminating the ability for a tuned signal to miss a particular sensitive frequency so if there IS any effect once the exposure is high enough to provide the energy it's far more likely to occur).

Most of rural America has to live with 1.5 Mbps, assuming you can afford the $80/month. So Europe is close to being 12 THOUSANDS times faster. How nice ;)
Oh, and for good measure, most of rural America also has no cable, cell phone, or DSL access either.
I don't blame the providers, who obviously have a profit objective. In fact, I don't blame anybody. But I would appreciate a national push to get cable everywhere, or at least put up satellites that can provide 10 Mbps download and 1 Mbps upload for a reasonable fee. That would enable much of America, which would like to telecommute, to actually do it from rural America. Having millions of Americans move out of cities and into rural America would relieve pressures on all population-density caused problems like traffic and crime.
Synchronizing stop lights across the US = one less nuclear power plant
In a feeble attempt to "slow down the world" and stop this gigabyte madness, I have decided to organize a contest to see who can get the SLOWEST wired access.
Mind you, very slow wireless may also be eligible for this distinguishing (or perhaps extinguishing) prize.
At THIS MOMENT, our advanced telephone engineers, in cooperation with the government of Quebec, are laying down a vast network of corroded copper wire to see how we can stop the perverse modernization of our great Quebec, and Canadian society
For results of an very promising initial experiment READ MY COPPER! and despair, o ye mighty!
Take note! We are QUEBEC! WE ARE FULLY PREPARED AND READY TO JOIN THE THIRD WORLD!
