Technology Backgrounder - CDMA2000 System Overview
Overview
This course is intended to give participants a good technology overview of the cdma2000 system so as to appreciate the operation of a CDMA cellular system. It provides an overview of cdma2000 technology and a high level view of the cdma2000 hardware, function, and associated nodes. This is followed by an intermediate level of understanding on cdma2000 concepts and terminology associated with the air interface. Major topics discussed include coding, modulation schemes, forward and reverse link channels, channel generation, high level call flow, forward and reverse link power control and handoffs mechanisms.
