Re: [802.3_EPOC] EPoC RF Spectrum Ad Hoc Minutes

Leo,

Any concerns with having the lower end of the downstream overlap the upper end of the upstream?  That under the assumption that in an FDD mode the upstream remains below the downstream, and that you'll need more than ~100 MHz to do 1 Gbps upstream (particularly with reasonable modulation, etc.).

Thanks.

Matt

Hi Steve,
I think my comments for the frequency limits are not clear in the minutes and need to be corrected. First, here is what I found for DOCSIS 3.0:

6 MHz Channelization
Tuning band (edge to edge):MUST 108-870 MHz
MAY 108-1002 MHz

8 MHz Channelization
Tuning band (edge to edge):MUST 108-862 MHz
MAY 108-1006 MHz

I think for both case, the tuning resolution is 0.25 MHz.

For the EPoC tuning band, I will recommend starting at 108 MHz. Because our OFDM block BW is 192 MHz, the center frequency will start at 204 MHz.

Thanks

Here are the minutes from yesterday’s Ad Hoc call.
