Methodology for WiMAX Performance Optimization Using Drive Test Data

This paper focuses on the performance of data services in mobile Worldwide Interoperability for Microwave Access (WiMAX) networks and development of a proper set of Key Performance Indicators (KPIs) that may be used to assess the network performance. Data collected via drive test from an already deployed network were analyzed with the goal to determine the QoS from the end user perspective. The analysis helps in determining what particular aspects of the network settings are causing degradation of the performance. It also provides appropriate course of action so that network operators may perform changes of the network parameters to improve the QoS of the network and boost customer satisfaction.
