40300 «WCDMA/UMTS Overview»

Course Code

40300

 

Description

WCDMA/HSPA operators worldwide quit often face the challenge of optimizing their 3G network in a very complicated and multi Radio Technology environment. Interference and capacity problems quit often force the predicted planned radio performance to deviate from the expected ranges, degrading the offered QoS to the end user.

In this course the audience will follow a methodology to find out problematic areas by drive tests or statistics, troubleshoot the problems and propose specific realistic solutions.

Case studies, exercises and real network projects will be presented, using also drive test tools and results
