IS-95 to IS-2000-A

This 5 day course provides a detailed survey of the IS-95B and IS-2000 standards, with practical descriptions of the important attributes and techniques associated with CDMA technology.

COURSE DESCRIPTION: This course begins with a summary of global wireless. It then shifts focus to the evolution from cdmaOne through cdma2000 standards, emphasizing the standardization and harmonization process and the attractive new features and services that make up 3G. The overview is followed by a detailed layer by layer explanation of the practical workings of CDMA technology. It provides the student with an in-depth description of the functioning of cdmaOne and cdma2000 systems according to key standards, including IS-95A, TIA/EIA-95B, IS-2000 and IS-2000A. In addition to examining the specifications, the rationale behind many of the design choices will be highlighted. Course discussions will provide a very detailed and insightful description of key processes in both cdmaOne and cdma2000, forward and reverse link channel operation including power control, spread spectrum signal generation, handoff techniques, call processing, registration methods, and the vastly improved higher layer functionality (MAC/LAC/L3) of cdma2000

OBJECTIVES: Upon course completion students should be able to:
