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
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
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.
www.cdg.org
Key Messages (Contd…)
•Meanwhile, EV-DO offers substantial longterm industry value by remaining the core
technology driving most operators’ ARPU
well into the next decade
•CDMA2000 operators will be among the first
enabled to augment their networks with by
wider-bandwidth OFDM-based solutions
• CDMA2000 WorldModeTM devices will enable this
competitive advantage
• CDMA2000 networks will be interoperable with OFDMbased radio technologies
• No need to deploy GSM or UMTS to obtain this advantage

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

Putting things into perspective:
Mass adoption of wide-bandwidth OFDM-based solutions
will take many years – Voice will remain the Killer
Application.

CDMA2000: Strong Evolution Path
CDMA ecosystem is continuing to enhance the CDMA2000 roadmap
• Mass market adoption of Rev. A advanced broadband services is strong
• 26 commercial operators in 18 countries (1/2 billion POPs covered) – 31 more in deployment
• Multicarrier Rev. B will meet demand for additional capacity well into the future
• Interoperability with OFDM-based broadcast and wide-bandwidth broadband
solutions will be supported to supplement core CDMA2000 services
