Abstract: - Many mobile operators around the world will implement 3G systems over the next few years and
will gain a competitive advantage in the marketplace as a result. The question will be whether the operators
can move to 3G economically, with a cost base that supports a viable business model and a path to
profitability. This paper presents the migration to all-IP 3G infrastructure based on CDMA2000 1xEV-DO
high-speed mobile data standard. A seamless deployment of 1xEV-DO with an all-IP architecture delivered
wireless multimedia offering significant financial, operational and technology benefits to a mobile operator.
