Wireless Traffic Concepts

Length: 2 days

Overview

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.
