New High Speed Wireless Chipset from IBM 62
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."

Ha! There's such an easy fix to that, but I'm afraid to post it here because some free-bandwidth zealot will take me seriously and do something about it...

O2 absorption (Score:5, Informative)
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...)

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?

Actually, there are folks using it over 2.5 km (with expensiv antennas, and NOT through walls) :

(I suspect that the 10m might actually be a feature to allow frequencies to be re-used)

Easy. Buy a few containers of surplus batteries cheap. ^_^
Seriously, though, it should be possible to create a open standard em-charge desk-cover that would power anything you put on it, like monitor, mouse, keyboard, printer, mobilephone, portable harddrive, etc.
Not exactly cordless, but at least it's only one cord for everything ontop of the desk.
There already exist such pads, but they are proprietary and small.

"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...
