| Prerequisites: |
| |
| This is an introductory course with no prerequisites. |
| |
| Course Description: |
| |
| This course provides a technical and business overview of current and coming CDMA technologies,
starting with a review of CDMA fundamentals and the 2G IS-95 standard. It then offers detailed explanations of
the prominent 3G wideband CDMA implementations, including TIA cdma2000 and ETSI/ARIB W-CDMA, so that you and your
organization can be ready to meet the coming challenges. Since the new 3G-CDMA standards are constantly evolving,
this course prepares the technical professional to understand and interpret virtually any CDMA standard that is
defined or that may emerge. |
