Two little words that could potentially give new life to copper, at least in the high-speed internet department, have found their way into the news once again, and this time it's Comcast who's showing us just what channel bonding can do. While you may have been scratching your head about Ambit Broadband's ridiculous claims, it looks like the technology may actually be edging closer to hitting the mainstream. Apparently, Comcast's CEO was able to demonstrate such a modem in front of the public and cable competitors alike, and while he claimed that it could reach speeds of 150Mbps, it was the testing that got everyone all riled up. Based on DOCSIS 3.0, the modem was able to download a 300MB file "in a few seconds," and he even snagged the 32-volume Encyclopedia Britannica 2007 and Merriam-Webster's visual dictionary in "under four minutes." Interestingly, it was noted that the FiOS competitor "could be available within a couple years," but if fiber crawls to our house before this stuff is ready to rock, it'll sure to be hard to hold off.
