  1. 1. Standardized Test Methods in Over-the-Air Chambers for FCC Part 27

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Oskar Hellström; [2023]
    Nyckelord :;

    Sammanfattning : Base stations (BSs) are the cornerstone that enables wireless communications. In order for a new BS variant to be imported and sold in the US they are required to undergo electromagnetic compatibility (EMC) testing. This testing is necessary to obtain their Federal Communications Commission (FCC) certification. LÄS MER

  3. 2. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

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

    Författare :Jessica Ye; Johan Lesko; [2023]
    Nyckelord :;

    Sammanfattning : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. LÄS MER

  4. 3. The Evolvement of the Wireless Industry Capability for Agile Service Production

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Gustav Curan; [2023]
    Nyckelord :5G; Software-defined networking; SDN; Programming;

    Sammanfattning : Along with the dramatic changes that have happened over the years, from the first-generation (1G) of mobile networks to the current fifth-generation (5G) of mobile networks. A wide range of different technologies has been seen as potential possibilities for changing and improving the 5G networks, whereas Software-defined networking (SDN) has been widely regarded as one of the significant enablers for this possibility.

  5. 4. Energy-Efficient Fixed-Coefficient FIR Filters for Millimeter-Wave Radios

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Erik Lundell; Gustav Molin; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : With the introduction of millimeter-wave antenna arrays in 5G base-stations and ever-increasing data volumes, the power consumption of the signal processing in digital radio systems has increased over the last decade. This, combined with increased cost and environmental awareness, has put focus on power optimization. LÄS MER
