Course Name: Wireless Traffic Concepts

 

Course Length: 2 days

 

Description: This course provides students with a fundamental knowledge base for wireless traffic concepts required to optimize customer service levels and equipment quantities.  This interactive course will provide lectures, discussions and exercises on: traffic and data terminology, proper usage of blocking formulas, and trunk sizing procedures.  The Wireless Traffic Concepts course will compare similarities and differences between the wireless and wireline networks to maximize connectivity.  Issues associated with data projection will also be addressed.

 

What You Will Learn: 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.
