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 CDMA2000’s 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.

  • 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
  • Low-cost devices *
  • Global roaming *

* Harmonization of spectrum for OFDM-based solutions will be necessary to build economies of scale and enable global roaming

Graceful CDMA to LTE EvolutionStandards alignment, driven by service providers

  • CDMA2000 core networks with IMS and VCC will play a key role in expanding 3G and 4G deployments
    • e.g. Seamless call handoffs between 2G, 3G and 4G networks
    • e.g. EV-DO and LTE femtocells
  • CDMA2000 operators will be among the first to deploy LTE
    • CDG’s evolution, device and roaming teams are working to ensure interoperability

Penetrating the Market

Next generation mobile broadband handset pricing trends will be similar to UMTS

Next generation multimode handsets will need to approach

existing handset prices to penetrate the market

and build economies of scale

cdma2000 strong global presence
CDMA2000: Strong Global Presence

CDMA2000 has built a strong ecosystem and enormous economies of scale

More than 276 operators in more than 102 countries have deployed or are planning to deploy CDMA2000

463 million CDMA2000 Subscribers

CDMA2000 will continue to be the core business

for hundreds of operators for well over a decade
