New High Speed Wireless Chipset from IBM 62

Posted by ScuttleMonkey on Monday February 06, 2006 @07:06PM from the yes-but-can-it-stop-frequent-disconnects dept.

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."

  60GHz signals are absorbed by oxygen (much like 2.4GHz is absorbed by water), so the FCC figured that frequency must be useless and the public might as well be allowed to play with it.

    I thought the molecule of oxygen (O2) is not polarized, so it should not absorb EM wave at any frequency by resonance? H2O and CO2 are polarized, and they obsorb 2.45GHz and 915MHz respectively. My chemistry is rusty though.

      Molecular oxygen is paramagnetic. It's explained by the permanent magnetic moment caused by the two unpaired electrons.
      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 [aps.org]
      So molecular oxygen is an exception to the generally true assumption that a molecule needs to be polar to absorb EM radiation.

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...)

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?

  60 GHz has one additional problem for longer ranges: Oxygen molecules have an absorption line rigth about there. So in addition to 1/r^2, you also get thermal degradation. But they can, of course go a bit up or down in wave length.

  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.

  Range isn't a problem at all. This doesn't replace Ethernet; it replaces USB, FireWire, VGA, DVI, RCA, optical, and HDMI cables (and it'll probably be cheaper than those high-end cables anyway). The short range makes this frequency ideal for unlicensed use, because interference also has a short range, and your private transmissions are much less likely to be intercepted. Thus it's an ideal replacement for short data cables of all kinds. I look forward to the day my mouse, keyboard, monitor, and printer

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 [doc.gov] The bottom row shows the allocation of frequency space from 30-300 GHz. Dense to say the least.

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.
