From the Paper:

"The CDMA2000 is considered to be a mode of the Radio Access 'Family' of Air interfaces approved by the Operators Harmonization Group for developing and facilitating integration of third generation-3G networks. One objective of such harmonization is to extend unlimited international roaming world wide between the different modes of 3rd Generation CDMA i.e. CDMA2000 and WCDMA. The use of common core technologies by Ericsson enables us to make compatible for the whole family of 3G CDMA modes. The CDMA Systems Ericsson Business Unit established in San Diego is considered to be the premier unit of Ericsson for devising the CDMA2000-compatible 3G infrastructure products. The CDMA 2000 is structured to reduce risks, safeguard investments and to extend significant performance boosts to operators as they extend their networks to offer 3G services. The CDMA2000 networks are also supportive to the CDMA-one applications, safeguarding the investment of operators in CDMA-one based networks and extending simple and cheaper transition to the next generation technology. Besides the CDMA2000 networks also ensures enhancement in the voice quality and voice capacity that is supportive for high speed and multimedia data services."
