  1. 26. 5G and The Industry : A Case of the Nigerian Financial Technology Sector

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Chukwunedum Nnamaka Elueze; Chibuzor Ugwunna Obasi; [2022]
    Nyckelord :5G; FinTech; Nigeria; Ecosystem;

    Sammanfattning : As globalisation and digitalisation continue to grow, cellular networks have become a mainstay in actualising digital communication, connectivity, access to digital media, and the exploitation of information technologies. 5G, the fifth-generation cellular network, has been anticipated by many to address the communications needs of virtually all sectors of the global economy and is expected to drive completely new services, particularly productisation, within niche markets.

  4. 28. Antenna Options for High Altitude IMT Base Stations (HIBS) in Cellular Networks

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

    Författare :Harald Magnusson; [2022]
    Nyckelord :High altitude IMT Base Station HIBS ; High Altitude Platform Station HAPS ; Link Feasibility; Coverage Feasibility; Phased Array Antenna; Parabolic Reflector Antenna;

    Sammanfattning : This thesis is the result of a collaboration between Ericsson AB and Luleå University of Technology. A feasibility study has been conducted to investigate antenna options for the HIBS access link. The study contains two parts. Firstly, a link budget investigating the gain required from the antenna.
