Course 581: CDMA Training - TONEX.com

CDMA training 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.

The following topics are covered:

• Spread Spectrum Techniques and Architectures
• CDMA Will Be the Dominant Mobile Telephone Technology
• Why CDMA Has Grown Rapidly
