UMTS allows operators to offer higher data rates and more capacity in their networks. This unique mentoring workshop delves deep into the behavior of UMTS in real-world environments, providing insights into the symptoms and possible causes of field performance issues. UMTS RF Optimization Mentoring is divided into three Instructor Led sessions that include all aspects of UMTS. The first workshop allows participants to gain in-depth knowledge of the subjects of coverage and containment, neighbor list tuning, access, and dropped calls. This knowledge transfer is obtained by allowing participants to gain hands-on experience using market specific tools, drive data, counters, and vendor OSS tools. During the coverage and neighbor list tuning section, the students will use market-specific post processing tools to analyze scanner data and to identify coverage and neighbor issues. Special Note: Market-specific network, configuration data, as well as statistical reports are needed three weeks prior to the course to deliver maximum value for the attendees.
Learning Objectives
After completing this course, the student will be able to: • Utilize multiple RF coverage plots to assess coverage and containment issues, using market specific tools (e.g. Actix and MapInfo) • Identify and prioritize coverage issues (i.e. polluting cells) and suggest corrective actions using market propagation tools • Understand vendor specific neighbor list algorithms • Uncover neighbor list issues using drive test post processing tools, as well as vendor’s OSS tools • Explain the random access and call setup procedures and list vendor specific parameters affecting access performance • Identify and troubleshoot access failures and dropped calls using market specific post processing tools • Utilize vendor OSS tools (e.g. UE and cell traces, event data, and reported measurements), as well system counters; to target cells with potential performance issues and troubleshoot the root cause of access failures and dropped calls, and suggest corrective actions
Intended Audience
This in-depth mentoring program is intended for wireless network operators, particularly RF professionals involved in cell planning and design, system design, RF engineering, and RF mentoring.
Suggested Prerequisites
• Vendor training as appropriate • Mastering UMTS Radio Protocols and Signaling (Instructor Led) • Mastering HSPA Protocols and Signaling (Instructor Led)
