Title LTE Performance Measurement In Trial Network & Validation Of LTE Performance Estimation Models:

University/Publisher Delft University of Technology
Abstract The drawback of theoretically based modeling approaches are that they lack knowledge about the performance and practicalities of the LTE radio interface features observed in realistic deployments. In this thesis, the problem is addressed by first measuring the LTE radio performance from a small scale trial network and by later comparing the results with simulations performed for similar usage scenarios. The main features chosen for investigation are the performance impact of activating the MIMO (Multiple Input Multiple Output) antenna technology in the downlink and the closed loop and open loop power control schemes in the uplink. The pdf file only contains summaries of the different chapters.
