New High Speed Wireless Chipset from IBM
YesSir writes to tell us IBM scientists are reporting that they have created a new low-cost wireless chipset that could allow devices to communicate up to ten times faster than current technology. From the article: "Using the IBM-pioneered chip-making technology called silicon germanium, the chipset is able to send and receive information in a portion of the radio spectrum that is both unlicensed and can carry a much higher volume of data, a key advantage as data-intensive digital media formats, such as HDTV, become more pervasive."
These guys just don't like free spectrum.
(It's never too late to join the Renaissance)
But how long will it take for a damn open source kernel driver to come out? Ndiswrapper is a pain.
Do not look into laser with remaining eye.
540Mb/s. Wow. Admittedly, this would be excellent for desktop usage in the average organization, but I still can't see wireless being used for servers - gigabit is just too essential to give up, plus there's the issue of setting up the infrastructure to handle 540Mb/s via wireless - I mean, hell, it's hard enough to share 54Mb/s for one access point as is when you've got 10 users on it, but still...
Striking fear in the authors of godawful fanfiction, I am here, appearing in darkness, Tuxedo Jack!
At first, it was just the radio. Nice background noise to do stuff to. Then they made wireless tv sets (like, battery powered...), which was ok. I could take them outside and take a quick break while studying. Then came wireless internet. No longer could I go somewhere and fight the urge to surf simply because I had nothing to surf with, so I began to grow some self-control. But wireless HDTV... Crap. Couldn't they at least wait until I've graduated?
Maybe they'll at least do something nice, like imbed it in some of those sunglasses with the built-in monitor so I can actually enjoy my lecture classes whilst only giving off the appearance of a hangover (which wouldn't be too far out of the norm...)
No trespassing. Violators will be shot. Survivors will be shot again.
How much will I have to pay for yet another router if I want this? Why can't we all just agree on one high-speed wireless standard?
Slow Down, Cowboy! It's been 60 minutes since you last successfully posted a comment.
Some applications that might now be possible using this 60 GHz technology include wireless personal-area networks (PANs) for intra-office communications in the 10m and below range.
So range is still a big problem. I'm sure that 10m is in an "ideal" environment as well, so they'll have to work out how to improve the range of this system. I guess the "easy" way would be to simply have repeaters everywhere, I'm sure the folks like Cisco are drooling at that prospect. Also wonder how it will do with interference, and if anyone else has any plans to utilize that area of the spectrum?
Of porn, actually.
You must be new here.
Even if this is a short range technology, it sounds like it could do away with just about every cable connection going into the back of my desktop box except the power cord. Let it be super Bluetooth... that would be great!
Any idea about how hot these things will be in a typical notebook? That will be an issue as well as their power consumption over time, especially during a boring 3 hour lecture, or when outside downloading a torrent.
For every present, there is a past
Seems like an improvement on blueTooth. I think this tech has a lot of potential. I suspect the small range is due to the fact that the antenna is embedded onto the chip. Maybe hooking up a booster antenna might help amplify the signal further.
higher you go the less dense a material it will pass through.
Only a part of the spectrum mentioned in the article (from 30-300 GHz) is 'unlicensed', and it is all 'allocated' to some use. A very informative chart can be found at: http://www.ntia.doc.gov/osmhome/allochrt.pdf The bottom row shows the allocation of frequency space from 30-300 GHz. Dense to say the least.
Not bad. Apparently this was designed for inter-satellite communication. I wonder what distance this could go in space.
I prefer the "u" in honour as it seems to be missing these days.
"IBM researchers said Monday that they have created a low-power chipset that will compete with ultrawideband technology, offering data rates at around 630 Mbits/s.
"The chipset conforms to the IEEE 802.15.3c specification, which IBM refers to as "millimeter wave" or "mmWave" technology, according to Brian Gaucher, a research manager with IBM Research. "
The bit where it talks about how the 630-Mbits was the limits of their test equipment was cool...
IBM just sold off the produciton and distribution of desktops and thinkpads to china.. They didnt sell off the research department, or 'PC server' production, or 'big iron'. ( unless they did this recently and didnt tell the rest of us ).

If you don't want 540Mb/s just keep your old router. It's not like 60GHz is going to interfere with your 2.4GHz signal.
Not the monitor, unless you plan to place the video codec within that one. (Surely a dream for the media companies...)
Why bother using this for intra-sat comms when you have intra-sat masers/lasers doing the same thing (and carrying much more data)? Perhaps there is a cost savings for systems not requiring the higher data rates... this is presumably an omnidirectional transmitter, or at least wide spot-beam, so the challenges of laser aiming would be negated.
At 300GHz, you have to have line of sight between transmitter and receiver. The wavelength is only 1mm, and you're not going to diffract around anything bigger than a broom handle. This will work more like an IR link.
Quoth JH Van Vleck: "Even though electrically non-polar, oxygen gas absorbs microwaves because the magnetic moment of the O2 molecule interacts with electromagnetic fields." The Absorption of Microwaves by Oxygen
So molecular oxygen is an exception to the generally true assumption that a molecule needs to be polar to absorb EM radiation.
If you want a vision of the future, imagine a youtube comments section scrolling - forever.
You know, even if it was only 5m of actaul usage, it wouldn't be so bad. if the tech is cheap, you just poke the antena through the ceiling, and you don't have to worry about any other wires. Most businesses have hanging ceilings, and most homes have attics. It sure would make the wiring easier. Plus with those speeds, you could have multiple devices in a room, and still have reasonable speed.
Of pirate porn!
Ewwwww. There are things a peg leg was just not meant to be used for.

That's a pretty flowery description.
