COURSE # TOO-351
WIRELESS DIGITAL COMMUNICATIONS SYSTEMS: SPECIFICATION, TEST, COMPONENTS, AND EVALUATION
Coherent review of the basic parameters, specifications and test criteria encountered in wireless digital communications.
Unprecedented growth in communications services is sweeping the globe and revolutionizing the basic premises and boundaries of this industry. Efforts to provide cost-effective, quality services coupled with the latest regulatory actions have pushed the state-of-the-art from analog to digital, from Frequency-Division Multiple Access (FDMA) to Time- and Code-Division Multiple Access (TDMA and CDMA). Moreover, these changes encompass the entire range of communications services, including audio, video, television, and local and wide area networks (LANs, WANs). With this vast proliferation of communications systems and new technologies, it is imperative to understand the operating characteristics, specifications, and testing and evaluation criteria of this equipment.
This course provides an overview of wireless digital communications equipment in use today and focuses on the critical specifications and test parameters, test techniques, and test equipment.
Applications and benefits:
You will benefit by enhancing your understanding of the :
- Operating principles of wireless digital communications systems.
- Test equipment and their operations.
- Specification parameters and figures of merit.
- Simple software-based analysis techniques.
- Correlation between the test equipment, communications systems specifications and the actual performance.
- Automatic test equipment (ATE) possibilities with IEEE 488. bus
Who should attend:
This course reviews the important parameters affecting digital wireless communication systems performance and focuses on the proper ways to specify, test and evaluate the sub-systems and components. The practical information presented should serve as an invaluable resource to Program Managers, Communications Engineers and Technicians, Verifications engineers, Specifications Writers, Incoming Inspection and Quality Assurance Personnel, and ATE personnel, who design, manufacture or use telecommunications equipment. This course has no prerequisites; however, for maximum benefit, participants should have a degree in engineering, science or equivalent experience in communications.
