Description
The Telecom optimization process is an ongoing process in which the first step is to collect data using the Drive test (DT). Through DT, different Key Performance Indicators (KPI’s) are checked and monitored so as to Detect problems in a network. There are multiple metrics like call drop rate, call failure rate, handover failure rate, handover success rate, etc. available which will determine what type of optimization is needed: Physical or parameter. Physical optimization includes tilt adjustments etc. The optimization process includes both Coverage and Capacity. This course of UMTS optimization covers the description of optimization of networks, coverage analysis, throughput analysis, etc. Optimization process – includes pre-optimization process, RF optimization, service optimization (AMR), service optimization (CS and PS), commercial launch, and continuous optimization. RF optimization mainly focuses on RF configurations like Frequency, Bandwidth, defining parameters for idle mode (Cell selection, Reselection), and Dedicated mode and further refining it further on the basis of results.To summarize, we will cover the description of optimization of networks, coverage analysis, throughput analysis, etc. We will also have a look at the principles and techniques that relate to the parameters available in 3G UMTS mainly cell configurations, idle mode, connected mode parameters, key performance indicators. We will dig into various optimization solutions, analyze radio and call drop issues, and various coverage improvement techniques. In all, this course will help you to learn various problems and solutions to the issues in the UMTS network.
