| Cable Future DOCSIS 2.0 with 256 QAM downstream and 16 QAM upstream will allow up speeds up to 30M Down/6M UP and 30M Down/4M up with a QPSK upstream.
DOCSIS 3.0 will allow speeds up to 100M Down/30M Up
The QPSK upstream speeds were tested from our offices in SE PA. The problem is maintaining a noise free HFC and keeping customer's modems below 50db return. So as much as the cable industry would like to increase speeds right away, it is not possible due to system designs without a complete rebuild. In any case, most of SE PA will be 16 QAM 15M/2M from QPSK 8M/768K by the end of the year with no "real" price increase. The combination of triple play and soon quad play should make things interesting. |
