  1. 11. Blixt™ : An Available Bandwidth Measurements’ Approach for High-Speed Mobile Networks

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Al-Hussein Hameed Jasim; [2018]
    Nyckelord :Network Performance; Active Measurements; Available Bandwidth; 4G LTE;

    Sammanfattning : Mobile networks are in the process of becoming the world’s leading medium for data traffic. This challenge has raised the bar for Quality of Services (QoS) provided by the mobile network operators. It requires methods and tools to verify the Service Level Agreement (SLA) and benchmark competitors by comparing metrics of QoS, e.g. LÄS MER

  2. 12. Closing of 3G Sites : Model for Decision Making

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Emmanuel Chaudron; [2018]

    Sammanfattning : The telecommunications industry faces difficult challenges as more and more devices communicate over the internet. A telecommunications network is a complex system with many parts and some are candidates for further automation. We have focused on interfrequency measurements that are used during inter-frequency handovers, among other procedures. LÄS MER

  5. 15. Optimized Codebook Based Hybrid Beamforming

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Juan Vidal Alegria; [2018]
    Nyckelord :UE; beamforming; codebook; phased array; antennas; detection; estimation; angle of arrival; 5G.; Technology and Engineering;

    Sammanfattning : In this thesis we research beamforming capabilities of the UEs equipped with several antennas in a 5G scenario. We define a system model based on the use of phase codebooks that allow to change the radiation patterns of the arrays of antennas installed in the UE. LÄS MER
