Re: MUL - Where to from here?
Anyone know what this technology means to satellite broadband?
BROADBAND WIRELESS
Rajiv Laroia was handed a dream assignment at Lucent's Bell Labs in 1997: Invent a way to put a broadband Internet in the sky. Don't worry about existing cell phone systems, just do it right.
Laroia had just spent five years in one of the last bastions of pure research, Bell Labs' mathematical sciences center. He likes to cut his lawn and iron his shirts because it lets him do more thinking. Nobody on his team even owned a mobile phone when they began the work. Seven years later Laroia has created an all-digital radio transmission technique that has won such fans as Nextel, Vodafone and Motorola.
Big wireless carriers need to deliver high-speed data without encroaching on the already-crammed spectrum devoted to voice. Easy-access Wi-Fi networks are beginning to challenge the cell providers. Laroia's solution is like Wi-Fi in the sky, only better. In February 2000--a month before the bubble burst--he quit Lucent, formed an outfit called Flarion and began raising a total of $150 million. Its scheme uses orthogonal frequency division multiplexing, which splits wireless signals into different frequencies and pushes data through relatively narrow windows of licensed spectrum without hiccups.
With a Flarion PCcard you will get wireless e-mail and Web access at a torrid 1.5 megabits a second, three times as fast as the latest cellular design and over a greater range than Wi-Fi covers. Carriers can handle data far more efficiently. Nextel has 2,000 customers on a Flarion network serving 1,300 square miles around Raleigh, N.C. It could cost $2 billion to roll out a broadband system with Flarion--but three times as much with current technology. "The vision is that every bit is wireless," Laroia says. "There's no need to be tied to wires."
