This seminar explores the enhancements provided by CDMA2000 and gives a detailed
view of the codes, channels, call processing, data capabilities, and network
architecture of Spreading Rate 1 (1xRTT) systems. It describes the radio
interface enhancements compared to IS95 technology and deals with the most
common deployments by the leading vendors in this market. Also described in this
course the 1xEV-DO technology.
