Re: [802.3_EPOC] EPoC Bandwidth Discussion

Jim,

Wikipedia defines bandwidth as follows:
Bandwidth has several related meanings:

  *   Bandwidth (signal processing)<http://en.wikipedia.org/wiki/Bandwidth_(signal_processing)> or analog bandwidth, frequency bandwidth or radio bandwidth: a measure of the width of a range of frequencies, measured in hertz
  *   Bandwidth (computing)<http://en.wikipedia.org/wiki/Bandwidth_(computing)> or digital bandwidth: a rate of data transfer, bit rate or throughput, measured in bits per second (bps

Unfortunately, as if often the case, we have multiple different definitions for the same term - as an RF nerd myself, I had difficulty getting used to "bandwidth" referring to data.  But the data usage certainly is a common use of the term.  If we need to differentiate the two, I'd suggest the shorter term "RF bandwidth" when we need to differentiate the two.

Thanks,

Steve,
Your use ot the term "bandwidth" completely threw me, I've always associated this term with data bandwidth.
Can I suggest we use something like Spectrum Channel Width - defined as a portion of RF spectrum dedicated to a transmission channel or sub-channel.
Once we agree on such a term Marek can then add this to the definitions list.
Best Regards,
Duane

EPoC Group,

               Several of us had a good discussion on EPoC bandwidth this morning.  I would like to see if there are other who would like to join us for future calls on Friday mornings (10 AM Pacific Time).

               If anyone else would like to join us, please send me an email and I will add you to the meeting invite.

               Once we have some slides put together we will review them on the Monday AM calls, hosted by Comcast.

Steve
