ibm's new fast transitor
ibm's new fast transitor
(OP)
In all the press over IBM's new 500 Ghz chips they
state this will allow cell phones to download a
High Def movie in 5 seconds.
Wouldn't such application need also enormous RF spectrum.
The IBM head semiconductor researcher is the one who
stated this application.

Meyerson forecasts that the advances will show up in real products within a couple years, probably in chips to power super-fast wireless networks capable of transmitting a DVD-quality movie in as little as five seconds.
Hype!

RE: ibm's new fast transitor
My computer can do millions of calculations per second, but if my 9600 Baud modem can't transmit the data, what's the point?

This is a good example of a research result being media-hyped into pure fiction.
A cell phone that operates at 5 degrees Kelvin is just a little hard to hold and talk into. Not to mention the lab full of cooling equipment needed to keep it cold!
RE: ibm's new fast transitor
I think the point is that high speed digital SiGe could have a lower power per transition at a given high frequency. For cell phones clock control is a good way to only use as fast a clock as needed since power is not linear with frequency. As operating voltages go lower, enabled by SiGe, then the energy in the capacitance goes lower, allowing more clocks to click for the same Joules.
I agree with 2dy4, the technology that enables the BW will be the key, not the digital technology. This was a headline grabber to put the impact of this in scope for the masses.
IBM already owns the IP for SiGe-C (with carbon) used in cell phones today for the RF. This is an important contribution that benefits humanity.

So, given quick fingers, one could actually have a monthly 'cell-phone' bill of around $10 million - not including air-time...
[Assumed $20 HD file every five seconds - YMMV]
RE: ibm's new fast transitor
yea, ve1bll, i agree.
Network provider's revenue will swell, ibm as well. What a breakthrough!
Maybe you could post its pros and cons.
