What You Will Learn

In this course you will learn the importance of identifying customer traffic characteristics on wireless networks.  Data collection and validation techniques will be explored in detail.  Students will learn how to apply various blocking formulas (Poisson / Erlang) to maximize customer service levels.  These concepts will facilitate the building and maintenance of an optimal trunk network.

Who Will Benefit From This Course

This course is recommended for anyone in the wireless industry responsible for the design, engineering and administration of traffic sensitive components in the wireless network.
