CDMA2000 is the next step in the evolution of the widely deployed IS-95 network. It is one of the technologies in 3rd generation wireless networks. Standardized by 3GPP2, CDMA2000 has introduced a new air interface, which offers new features to support new services. The CDMA2000 air interface is designed to maintain backward compatibility with IS-95 networks. The key enhancements in CDMA2000 air interface are increased capacity over the air interface and support for packet data services.
This course provides a detailed description of the new CDMA2000 air interface. It details the features added to support packet data and how CDMA2000 offers increased capacity compared to IS-95 networks. This course clearly explains how the CDMA2000 networks can coexist with IS-95 networks.
