Course Name:		RF Optimization Training
Deployment Options:		Onsite - Instructor-Led Training
Course Duration:		4-5 days depending on audience background and options

Introduction:

This 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.

Audience:

Engineers new to the field of RF engineering, managers, or other personnel responsible for RF systems whether wireless, cellular/mobile, microwave, or other, will benefit from a comprehensive understanding of RF optimization, spectrum utilization, spectrum planning and capacity and quality of service management for RF systems. An electrical engineering degree or equivalent background is desired, but not required.

Prerequisites:

You should have some familiarity with communications engineering. If you have an understanding of the architecture of a mobile communications network and the limitations imposed by its air interface, that will be helpful but it’s not required.

Customize it:

This 4-5-day RF Optimization course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.

Objectives:

Provide an understanding of RF performance degradation issues, testing and measurement techniques, data collection methodologies, post processing methodologies and tools, drive testing, model tuning, spectrum planning, hand off considerations, morphology analysis, cell splitting, antenna tilt azimuth, noise, SNR, BER, SIR, frequency planning, interference, in order to allow engineers and technical personnel to manage and maintain system performance of RF related systems.
