COURSE # TOO-331
CDMA IS-95 SYSTEM OPERATION AND TECHNOLOGY
?beginning with CDMA concepts and covering CDMA systems operation, the class offers a clear standards-based presentation emphasizing the radio techniques, signaling, protocols, and system issues?
The worldwide growth of cellular services places significant demands on technology to provide nearly wireline quality services together with mobility, expanded coverage, capacity, and new features. The transition from analog first generation systems to today?s second generation digital systems has been characterized by competing incompatible standards: GSM, TDMA and CDMA. A significant number of network operators have selected a narrow band CDMA technology called TIA/EIA-95-B (also called IS-95) to sustain them into the third generation era. Today, CDMA provides reliable mobile telephony services in many markets, and some of its radio techniques are the basis for most third-generation (3G) systems.
The course concentrates on the unique radio techniques of CDMA and its signaling resources, as it strictly avoids mathematics and rigor in favor of offering an intuitive understanding of CDMA as a mature and successful wireless system. The course covers the IS-95 radio techniques and protocols, and then continues with the practical aspects of deployed CDMA systems. It concludes with a look at how CDMA can easily evolve into several forms of third-generation (3G) networks.
Applications and benefits:
You will benefit by enhancing your understanding of:
- Role of CDMA among all technologies and standards in mobile radio.
- Behavior of CDMA systems through its signaling routines.
- Unique CDMA aspects: power control and soft handovers.
- Practical aspects of deploying and managing a CDMA system.
- Current CDMA migration paths to the third-generation (3G).
Who should attend:
This course offers an intensive radio, protocol and standards oriented overview of IS-95 applicable to a wide range of wireless interests. It concentrates on the aspects of CDMA that, unless thoroughly understood, become permanent barriers to efficient work in this standard: SSMA (Spread Spectrum Multiple Access), power control, soft handovers, and the signaling aspects that support the unique radio techniques of the system. It has been developed for project managers, system engineers, test engineers, performance engineers, technical marketing professionals, and all others responsible for product development, system operation and interoperability issues.
Although the course has no prerequisites and is specifically designed for a wide range of interests, it assumes general familiarity with telecommunications networks and technologies, cellular radio systems, and digital radio technologies. Those new to the industry and/or not yet familiar with telecommunications networks and wireless systems may find it useful to first attend OEI Course #TOO-319, Engineering Foundations of Cellular and PCS Communications Systems, which lays the foundation for the more advanced, standards-specific courses offered by OEI including TOO-331, as well as Course #TOO-368, GPRS and EDGE Systems Operation and Technology, and Course #TOO-378, WCDMA and UMTS Systems Operation and Technology.
