Detailed industry report explores the future convergence of mobile broadband wireless services and CDMA’s critical role as a core technology

CTIA WIRELESS 2008—LAS VEGAS—March 31, 2008 — The CDMA Development Group (CDG) today published a white paper entitled “CDMA and OFDM: The convergence of wireless broadband services,” now available for download on the CDG’s Web site ( The report provides detailed insight into the future convergence of mobile broadband services and the role CDMA2000® will play as a core technology, as wider-bandwidth OFDM-based technologies are deployed to complement existing networks and services.

The white paper supports the CDG’s overall mission to educate the industry on the merits of CDMA technology, particularly at a time when confusion prevails regarding the as-yet undefined “4G” technologies and what those will mean for current 3G CDMA networks. Central to the CDG’s perspective is the hypothesis that the “one technology fits all” approach to meeting today’s telecommunications requirements will not hold true in the next generation of mobile broadband solutions. Rather, operators will match particular applications and services to the technologies that best suit them. 3G CDMA will remain the leading and most economical platform to deliver core mobile broadband services, and operators will use OFDM-based systems such as LTE, UMB, WiMAX, DVB-H, MFLO, T/S-DMB, ISDB-T and Wi-Fi (802.11n) to complement those services with additional features and broadband capacity.

“This CDG white paper demonstrates why CDMA2000 operators are well-positioned to continue to grow revenues from their existing networks as the industry evolves,” said Perry La Forge, executive director of the CDG. “Just as we’ve seen in previous technology upgrades, the move to OFDM-based technologies will be a phased adoption that will lean heavily on existing infrastructure assets as core business solutions. The 3G capabilities and flexibility of CDMA2000 in make it the most attractive solution for interoperability with wider-bandwidth OFDM-based technologies.”

The paper supports the following primary assertions:

  • CDMA and OFDM-based technologies are different technologies with different capabilities
    • For bandwidths (up to 5MHz), CDMA technologies can achieve some of the highest data throughputs possible, while OFDM-based technologies can offer a simpler implementation within wider radio channels (greater than 10MHz)
  • OFDM-based backhaul, broadcast and broadband networks will complement CDMA2000 networks
    • Augmenting CDMA2000 in high-teledensity areas and leveraging CDMA2000’s ubiquitous coverage with multimode devices to provide seamless continuity of services
  • Global mass market adoption timing of wider-bandwidth OFDM-based solutions is uncertain
    • 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 technologies will continue to be enhanced to offer long-term industry value and remain the ‘core technology’ platform for mobile telephony and broadband communications revenue well beyond the year 2020.
  • CDMA2000 operators have and will be among the first enabled to augment their networks with wider-bandwidth OFDM-based solutions.
    • There is no need to deploy GSM or UMTS to obtain this advantage
