      technology, pioneered by QUALCOMM, provides excellent voice capacity and 
      data capability for mobile and fixed wireless networks. Because of its 
      advantages, CDMA serves as the foundation for 3G services worldwide.
 CDMA works by converting speech into digital information, which is then 
      transmitted as a radio signal over a wireless network. Using a unique code 
      to distinguish each different call, CDMA enables many more people to share 
      the airwaves at the same time — without static, cross-talk or 
      interference.
 
 Commercially introduced in 1995, CDMA quickly became one of the world's 
      fastest-growing wireless technologies. In 1999, the International 
      Telecommunications Union selected CDMA as the basis for 3G wireless 
      systems. Many leading wireless operators have commercially launched or are 
      now upgrading to 3G CDMA networks in order to provide more capacity for 
      voice traffic, along with high-speed data capabilities.
 
 Today, more than 180 million users worldwide rely on CDMA2000, WCDMA (UMTS) 
      and cdmaOne for clear, reliable voice communications and leading-edge data 
      services.
 
 Key Attributes of CDMA:
 
        Direct sequence spread 
        spectrum
Universal frequency reuse
Seamless soft handoff
Multipath propagation for 
        diversity
Variable-rate transmission
Unique forward and reverse 
        links
