CDMA 1xEV-DO Better Than W-CDMA - report |
A
That is one of the major conclusions of a new research report, "CDMA2000
1xEV-DO Opportunities, Challenges & Competitive Strategies", now available
from Alexander Resources, a leading research, consulting and education
firm specializing in wireless communications.
The report also concluded that Wi-Fi hotspot services will not eliminate
the need for 3G wireless technologies such as CDMA2000 1xEV-DO and that
the business case for Wi-Fi hotspots as a substitute for 3G is flawed.
Wi-Fi hotspots are best suited to serving notebook PC users in select
airport, hotel, and restaurant locations.
Additionally, delays in deployment and acceptance of WCDMA phones and
networks presents a significant window of opportunity for carriers
deploying EV-DO. However, wireless carriers may be in danger of missing
the time-to- market, cost, and performance advantages offered by EV-DO by
not accelerating deployment of this technology in their networks.
Additional conclusions found in this new report include:
-- EV-DO frees carriers from the false dilemma of charging data users for
the equivalent voice resources consumed. Using dedicated bandwidth
carriers can develop mobile data as an independent business.
-- Many CDMA2000 carriers look at EV-DO as a competitive insurance policy
should WCDMA start to take off. Because EV-DO can handoff to CDMA20001x,
it can be deployed by carriers where needed to meet
customer needs and competitive requirements -- avoiding WCDMA's large-
scale deployment requirements.
-- The success of EV-DO will reduce future demand for current CDMA 'data-
voice' (EV-DV). The latter will mainly be relegated to carriers with
insufficient spectrum.
