Comcast's CEO demonstrated a DOCSIS 3.0 cable modem today running at a speed of 150Mbps. It works by building on DOCSIS 2.0 to include channel bonding of up to 4 channels. The real question to be asked is why we need this. Comcast could be using DOCSIS 2.0 with its 45Mbps limit and still not come anywhere near that speed. Even with DOCSIS 3.0 approved, the tech won't hit consumers for at least another year and isn't likely to be available to more than 40% of cable subscribers by 2012.
If you make a really fast Internet service and don't make it available, does it even matter? Survey says no.
