The goal of the course is to give an understanding of the capabilities of the system and how it can help users to improve quality of service for their network subscribers. Advanced users will be introduced to new network applications. The instructors for this course are experts in using Actix solutions to increase productivity, and are familiar with the challenges faced by engineers working in cellular/PCS environments. Class size is limited to ensure that everyone receives extensive one on one instruction. Participants have many opportunities 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. The GSM, UMTS and HSPA Spotlight Training Course begins with a high-level presentation of the Actix platform interface and its capabilities. We will then cover how existing optimization processes can be tailored to the specific needs of the participants. 7 Actix Spotlight GSM/UMTS/HSPA Training Course October 2010 l 2009 Edition A Who should attend this training course? RF Engineers responsible for enhancing cellular performance and implementing wireless system optimization. Engineers looking to further understand the application of log file 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 and a familiarity with the Actix software platform. Basic computer literacy, including familiarity with Windows and MS Office applications. 8 Actix Spotlight GSM/UMTS/HSPA Training Course October 2010 l 2009 Edition A Aims of the course After this course, you should be able to: Appreciate common network problems and how they are classified in Spotlight. Configure Spotlight to work with your data and methodologies. Appreciate pre-defined Spotlight Reports. Appreciate different analyses methods (Event Based and Radio Network Analyses) in Spotlight. Use Spotlight to analyze problems in data sets of differing sizes. Appreciate the role thresholds perform in Spotlight and how to modify them. From the Repository Analysis - Drilldown, you should be able to: Add extra data during the analysis. Save the project file. Create and save your own template for your project. Start Spotlight and reload the project file. Drilldown problem by File or Time to message level with or without loading the whole file. Perform different analyses based on handset and scanner data. Perform 3G-2G Neighbor Analysis for UMTS/HSPA 9 Actix Spotlight GSM/UMTS/HSPA Training Course October 2010 l 2009 Edition A Solving common network problems with Spotlight With the Seek-See-Solve approach, Spotlight is designed to allow you to follow your own investigations throughout the various analysis pages and reports. However, a typical path through Spotlight is to start from the Summary Dashboard, examine the summary map and then the appropriate report for the loaded data, which might indicate the presence of one or more problems. Spotlight breaks these problems down into two groups: critical issues, where an event has occurred that discontinued a call, and important issues, where the quality of service has been reduced without necessarily ending any calls. Cell coverage, interference problems and GSM/UMTS/HSPA visualization can be investigated from the Radio Network Explorer analyses (links to these are shown as Important Issues in the Issues panel of the Summary Dashboard). These then point you at specific problem events which you can examine and diagnose using the Event Explorer (links to these are shown as Critical Issues in the Issues panel). 10 Actix Spotlight GSM/UMTS/HSPA Training Course October 2010 l 2009 Edition A Actix Spotlight Features The following Actix Spotlight features are available for GSM/UMTS/HSPA: Radio Network Analyses For GSM: Coverage and Overspill Analysis Determines the coverage footprint of cells and identifies overshoot against coverage design boundaries. 2G Missing Neighbors Analysis Lets you use scanner data to optimize neighbor lists for sites within a user-defined radius of the selected cell. For UMTS/HSPA: Cell Coverage Analysis (based on Scanner/Handset data) It determines the coverage footprint of cells and identifies overshoot against coverage design boundaries. Missing Neighbors Analysis (3G-3G, 3G-2G) Pilot Pollution Analysis (based on Scanner/Handset data) Event-based troubleshooting Automated root-cause diagnostics for the most common subscriber problems such as call drops, call setup failure, location update failures, handover failures, lack of pilot dominance issues and HSDPA low throughput issues. Reporting Integrated, professional-quality reports including embedded maps. [...]...
