This course will serve as landmark for the professionals looking to enhance their skills in the Performance , QoS and Benchmarking of Mobile Networks.
3 This course will focus on 2G, 3G and 4G Networks. While Performance Monitoring tools will also be discussed in this comprehensive course. Performance measurement tools and techniques allow the quantification of the problems and solutions. Definition and reporting of KPIs is also covered to benchmark operators on common grounds. Key Performance indicators (KPIs) in GSM, UMTS, HSPA and LTE are defined through the definition and measurement of key parameters of input and output of internal network system and/or maintenance & operation progress of mobile network operations.
4 Key Performance Indicators are a set of quantifiable measures used in GSM, UMTS, HSPA, and LTE networks to gauge or compare Performance in terms of meeting mobile network s strategic and operational goals. KPIs vary between management, marketing, operations and network engineering people depending on their priorities, perspectives or Performance criteria sometimes referred to as key success indicators (KSI) . This ETS s Workshop is designed to provide a strong foundation to deploying relevant and feasible KPIs for 3 GPP RAN and Core networks. By completing this Training Workshop, you will gain both the theoretical knowledge of KPIs and practical skills of using a variety of Performance management techniques and methods for KPI planning and development.
5 This workshop is ideal for professionals who optimize 3 GPP RAN , Core and regulate and Performance Monitoring professionals. Pre Requisites Some knowledge of GSM network components Who Should Attend? Regulatory and enforcement Engineers / managers, Network Performance and QoS Engineers, Technical Managers, Development Engineers, Planning & Optimization engineers , Performance Monitoring engineers.
