iVEST A: Interactive Data Visualization and Analysis for Drive Test Data Evaluation

In this thesis, a practical solution for drive test data evaluation and a real
application are studied. We propose a system framework to project high dimensional
Drive Test Data (DTD) to well-organized web pages, such that users can visually review
phone performance with respect to different factors.
The proposed application, iVESTA (interactive Visualization and Evaluation
System for driven Test dAta), employs a web-based architecture which enables users to
upload DTD and immediately visualize the test results and observe phone and network
performances with respect to different factors such as dropped call rate, signal quality,
vehicle speed, handover and network delays. iVESTA provides practical solutions for
mobile phone manufacturers and network service providers to perform comprehensive
study on their products from the real-world DTD.
