Scope
This two-day class introduces LTE event processing from the perspective of the messaging protocols and presents messaging examples for in-class analysis. Commonly available system performance statistics and field data are presented and methods of optimizing RF and network performance are explained.
Target Audience
Designers of LTE networks, operating engineers and technicians, and those responsible for providing and dimensioning transport/backhaul to support LTE operations for a favorable customer experience and effectively managed costs.
Course Presentation Setting and Methods
Presented in a classroom setting with computer projection/student workbooks.
