4G Wireless Network Winners and Losers

As Wireless Network Speeds Increase, OFDM will Edge out CDMA

DALLAS, Texas, April 26, 2005 – The race for the next generation 4G wireless networks is on again, with OFDM pitted against CDMA2000 and WCDMA. The growing use of streaming media and other high-speed applications may allow OFDM-based solutions to beat CDMA and WCDMA in the race for 4G dominance. But, while OFDM and MIMO-OFDM have advantages as the wireless industry moves to higher speeds, CDMA2000 or WCDMA still has a long way to evolve and it may be several years before vendors must switch to OFDM. These are but a few of the conclusions from the new 46-page report, Hard Numbers and Experts’ Insights on Migration to 4G Wireless Technology now available from Alexander Resources, a leading research, consulting and education firm specializing in wireless communications.

Additional conclusions found in Hard Numbers and Experts’ Insights on Migration to 4G Wireless Technology:

  • OFDM has inherent advantages over CDMA, but the advantages are only sufficient to warrant migration at high data rates. This report identifies and discusses the cross-over point.

  • Though CDMA vendors are continuing to support and evolve CDMA-based solutions, many are also implementing or reselling OFDM-based solutions.

  • The technical designs of evolved CDMA technologies such as wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA) and 1xEV-DO Rev A are converging. As described in the report, OFDM based systems also use many of the same methods and tools as CDMA-based systems.
  • OFDM and MIMO-OFDM are already key components of advanced and next-generation wireless technologies in the LAN (802.11a, 802.11g and 802.11n), MAN (WiMAX), and mobile (Flarion’s Flash-OFDM) industries. 

Hard Numbers and Experts’ Insights on Migration to 4G Wireless Technology provides detailed information on how OFDM technology performs relative to CDMA, its effectiveness in the mobile environment and in what scenarios it will offer advantages over other technologies. This authoritative report provides concrete numbers, a detailed analysis of the relative benefits of different technical approaches and the insights of pioneering experts on the advantages and limitations of both CDMA- and OFDM-based solutions. The report also quantifies the spectral efficiency of a wide range of existing and forthcoming mobile wireless technologies in various configurations, illustrating the gains from techniques such as receive diversity, channel equalization, and MIMO.
