Lightwave: By 2006, one half of U.S. households will subscribe to broadband access, and a shift to much higher data rates in the range of 24 Mbits/sec to 100 Mbits/sec will have begun, contends a new report from Technology Futures. By 2010, U.S. broadband penetration of 75% is likely, and 10% to 20% of U.S. households will subscribe to very high-speed-broadband.
