DOCSIS 3.0 boosts cable modems to 150Mbit/s

The cost of modems that would support the technology, called "channel bonding," is "not that dissimilar to modems today," he told The Associated Press after a demonstration at The Cable Show. It could be available "within less than a couple years," he said.

The new cable technology is crucial because the industry is competing with a speedy new offering called FiOS, a TV and Internet service that Verizon Communications Inc. is selling over a new fiber-optic network. The top speed currently available through FiOS is 50 megabits per second, but the network is already capable of providing 100 Mbps and the fiber lines offer nearly unlimited potential.

The technology, called DOCSIS 3.0, was developed by the cable industry's research arm, Cable Television Laboratories. It bonds together four cable lines but is capable of allowing much more capacity. The laboratory said last month it expected manufacturers to begin submitting modems for certification under the standard by the end of the year.

In the presentation, ARRIS Group Inc. chief executive Robert Stanzione downloaded a 30-second, 300-megabyte television commercial in a few seconds and watched it long before a standard modem worked through an estimated download time of 16 minutes.
