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.
