.................................................................................. 119 Introduction Scope of the course Troubleshooting and Optimizing UMTS Network workshop provides a comprehensive overview of the integration and radio optimisation procedure for WCDMA networks making use of the Actix Analyzer. Our goal is to give new users an understanding of what Analyzer can do and how it can help them improve the quality of service for their network subscribers. Advanced users will be introduced to Analyzer features they may not know about and to new network applications that can be performed using Analyzer. The instructors for this course are experts in optimising 3G networks and are familiar with the challenges faced by engineers using measurement and post processing software. Class size is limited to ensure that everyone receives extensive one on one instruction. Participants are given ample opportunity to ask questions relevant to their particular optimization needs. Upon completing the course, participants will be able to use what they learned in class to identify and solve real network problems. Troubleshooting and Optimizing UMTS Network workshop begins with a high level presentation of the Analyzer interface and its capabilities. We will then cover how Analyzer can be customized to tailor existing optimization processes to the specific needs of the participants. We will try to establish procedures and create Analyzer customized solutions for these procedures Who should attend this training course? Engineers responsible for enhancing cellular performance and implementing wireless system optimization. System Performance Engineers responsible for measuring and quantifying network quality relative to competitors and/or established benchmarks. Engineers looking to further understand the application of drive test, call trace and protocol data in optimizing networks. Experienced technicians involved in field optimization. Anyone looking to maximize the return on investment in Actix software. Prerequisites Familiarity with network infrastructure and operation of the air interface. A general understanding of drive test and call trace collection and post-processing methodology and advantages/limitations with each dataset. Access to Actix software. Basic computer literacy, including familiarity with Windows and MS Office applications.
