Light Reading's Hall of Fame: The First Five
Even in the 1980s, copper was presumed to be too slow for the communications of the future. Fiber was the way to go. But Cioffi's research into discrete multitone (DMT) modulation paved the way for high-speed copper communications.
The DSL industry ignited after Cioffi founded Amati Communications, which went public and was eventually acquired by Texas Instruments Inc. (NYSE: TXN) in 1998. (Through another acquisition and a spinoff, the Amati heritage is now in the hands of Lantiq Semiconductor .)
Cioffi is still cracking DSL. His more recent research focused on dynamic spectrum management (DSM), now the basis of startup Assia Inc. , founded in 2003. But it's his initial work in laying a foundation for broadband that has cemented his place in the Hall of Fame.
