Disruptive Technologies For Next 5 Years
prostoalex writes "America's Network magazine, the publication serving to telecom industry, takes a look at the disruptive technologies over the next five years. Disruptive, naturally, for telecom industry. Virtual keyboards, DWDM, broadband connections using powerlines, wearable computers, free-space optics, low-power devices, UltraWideBand, voice over 802.11b and numerous others are discussed, as well as their potential for development over the next five years."
The technologies mentioned are, I think tremendously exciting! DWDM is something I've always thought of ever since I got into computer engineering; a natural use for fiber. And the electrical power line broadband --- this can truly extend broadband to the far reaches of the globe in areas where the power distribution system allows it.
But note the negative tone in the article - "Here are the technologies ... that are coming to disrupt your business". Am I misunderstanding the meaning of "disrupt"?
I think there's something wrong if our business leaders are looking at technology advancements as problems. Adapt, you stupid sh*ts! Get off your lazy asses, hire competent people in the new fields, and make a fortune.
There was an article in the December 2002 issue of IEEE Spectrum ("Paving the Last Mile With Glass") that talked about phone companies struggling to match cable companies in offering services via fiber optic connections in homes. Same idea. The phone companies that adapt to this technology advanacement remain. The others ("oooh no, it's disruptive, I'm scared!") disappear.
You can get a cell phone from Virgin for $60. Talk time is 25 cents a minute for the first 10 minutes, and 10 cents after that. What's so great about that? NO PLAN. You just buy these cards with extra minutes on them whenever you need more time to talk. Why should I spend $38 a month on home phone service? I rarely talk on the phone. Even if I make one 4-minute call each day, it'll still only add up to $30 a month. For the young single person, these are perfect.

I'm not convinced that you will be able to demonstrate tremendously better power utilization in practice vs. a spread-spectrum system with similar characteristics.
Huh?
You're not trolling me are you ? There is a very clear AND appreciable difference and the differences are rooted in communications theory. For similar data rates UWB has a dinstinct power advantage for multiple reasons which include the back-end processing. In other words the digital circuitry which handles the data is simpler and so there is a structural advantage. I guess we'll have to define "trememndously". As much as batteries still suck, I define trememendously as may be a 3x or 4x improvement, i.e. I claim that a 10Mbit/s radio which needs 1W, like 802.11B for instance, will only need .25 - .3W. And that's very conservative.
I do agree that there is plenty of hype to go around on the UWB front and one should always be skeptical. The fact is that the hardware is significantly simpler than other radios and that includes bluetooth. So it will always maintain a cost advantage. Now if that advantage is $0.5 then yeah - who cares.And remember that Bluetooth had a lot of kool-aid associated with it. So far it is failing to deliver spectacularly, at least in the states.
Absolute statements are never true
