Re: [STDS-802-3-EPOC] PLC FEC presentation



Avi, 

 

Just one general comment - when we started the PLC discussions, the whole
concept was focused on a low-latency, low complexity channel that requires
no FEC, no interleaver and no fireworks to make it work under the worst
conditions. As we go along the path, I see more and more often FEC being
added to the mix. I understand we need margins to work effectively, but now
we are talking about a data link channel that is becoming increasingly
complex just to guarantee that we can exchange the ~1 Mbit/s worth of data.
The question then becomes. Can we come up with something different, that
does not require bidirectional communication prior to establishment of MAC
link and skip all the inherent complexity of adding FEC into PLC? 

 

I am concerned that at the end we will have a similar level of complexity in
the PLC link as well as the main MAC link, making the whole idea of PLC just
unattractive to start with. Then it is just simpler to start the whole MAC
at a lower rate to begin with and forget about PLC altogether.
