Key Messages

• CDMA and OFDM are different technologies with
  different capabilities
• CDMA2000 offers high-performance mobile
  broadband and voice services today and will
  continue to be enhanced to provide greater
  broadband speeds and voice capacity
• OFDM leverages wider-bandwidths up to 20 MHz to
  provide greater speed and capacity
• OFDM-based backhaul, broadcast and broadband
  networks will complement CDMA2000
• Augmenting CDMA2000 in high-tele density areas
  and leveraging CDMA2000s ubiquitous coverage
  with multimode devices to provide seamless
  continuity of services

Notes 1. OFDM is the air interface used by WLAN,
mobile broadcast and next-generation mobile
broadband technologies (LTE,
etc.) 2. 4G will be defined by the
ITU-R as a result of the IMT.Advanced
standardization effort.

Key Messages (Contd)

• Global mass market adoption timing of
  wider-bandwidth OFDM-based solutions will vary
  from Market to Market
• Wider-bandwidth spectrum availability will drive
  OFDM-based network deployments
• Mass market adoption of OFDM-based solutions will
  depend on ubiquitous coverage, low-cost handset
  availability, VoIP replacing circuit-switch voice
  services and roaming

• 3G CDMA WAN networks will coexist with OFDM-based
  solutions until
• next generation broadband networks are fully
  capable of delivering
• Ubiquitous coverage
• Carrier-grade VoIP
