Re: Dream Modem - 24x8

then you need a dream cable system

8 upstreams is wayyy overkill unless you go with a mid or high split system....most all system in the US are sub split. 5-42mhz...so even if a MSO started putting carriers at 15mhz (dear god please dont) and they are all 16qams then youre looking at about 11 carriers...more like 10 if you account for rolloff on the high end.....

so no company will really invest in modems with more then 8 carriers...4 is plenty IMO...

BTW - There was an article on the Light Reading Cable site just yesterday that discusses the current issues with upstream bandwidth and speeds:

An article on the Light Reading Cable site today about the possibility of using Synchronous Code Division Multiple Access (S-CDMA) carriers in the upstream in order to increase uplink speeds:

No cable system today will be supporting it without some major changes.

If any MSO "wastes" (and I use that term loosely) 32 QAM's on HSI, I need to have a talk with their management.
