Brady Volpe and John Downey discuss DOCSIS 3.1 Channel Bonding.
With the differences in baud rates and the sharing of time slots, should we be bonding the 3.0 and 3.1 on the upstream?
My question is around the idea that if we do not bond the 3.0 would get access to all the time slots and not be waiting on 3.1 users.
Additionally, how do the different baud rates interact when bonded. My understanding is that OFDM uses longer symbol rate which means a lower baud rate.
If we allow the 3.0 to run without bonding is it actually faster than it is when bonded, almost twice the rate or is the rate 2X the OFDM rate and this works fine? Especially if we let the SC and OFDM run independently and allow two users to send concurrently rather than waiting on each other.
With timing and baud differences, are we better off allowing two upstreams to run independently and not bond them?
I have similar question on the downstream.
Should OFDM and SCQAMs ever be bonded? With the differences in baud rates is OFDM holding the SC-QAM from being as efficient as it could be. Since OFDM is very wide in QAMs and SC is narrow it seems these would be easier to manage and work more efficiently if they are not bonded.
