Re: poor ethernet performance?

[Matthew Dillon]

:       I know, I'm just wondering how did they get more frequency out of
:wire of the same size.  I can understand it if the wire was a larger
:guage.

    For twisted pair, Less power == less crosstalk.  Plus the higher 
    bandwidth transceivers use better receivers and better pre-attenuation
    of the signal. 

    I'm not sure what the gigabit copper ethernet people are doing, but there
    are other ways as well. 

    Basic ethernet uses baseband which is quite noisy even with the
    preattenuation, so there was lots of room to go faster.

                                        -Matt
