RF Optimization Training

RF Optimization Training Course with Hands-On Exercises (Online, Onsite and Classroom Live)

This RF Optimization Training course is a four day intensive training and workshop designed to teach the fundamentals of RF optimization, data collection, root cause analysis, system trade off considerations in order to maintain and improve subscriber quality of service for both GSM based and CDMA based modulation technologies.

This four-day RF Optimization Training course also builds competence in the principles and present-day practices used to improve the operating performance of modern wireless systems. Core performance indicators are thoroughly explored and desirable healthy operating conditions are identified. Both system-side and mobile-side performance-monitoring tools are introduced. The main operating parameters are identified along with the considerations necessary to properly set them in real systems.

This RF Optimization Training course is designed for individuals and anyone needing a solid foundation for understanding the principles of RF optimization. Engineers, technicians and managers who are new to RF and require applicable skills in RF design, planning and engineering. Engineers and Technicians responsible for designing, maintaining, monitoring, and/or optimizing performance of wireless systems
