At the National Cable and Telecommunications Association meeting in Las Vegas, Comcast has unveiled its future weapon against the competition: a modem three times faster than FiOS. The DOCSIS 3.0 technology ties four cable lines together. The cable modem, developed by the Cable Industry"s Cable Television Laboratories, could be available in a few years. It reportedly features a broadband download speed of 150 Mbps – in the Las Vegas demo, a 32-volume copy of the Encyclopedia Britannica and Merriam-Webster"s visual dictionary were downloaded in less than four minutes. "If you look at what just happened, 55 million words, 100,000 articles, more than 22,000 pictures, maps, and more than 400 video clips. The same download on dial-up would have taken two weeks," said Comcast chief executive Brian Roberts.
