  1. 1. Using search based methods for beamforming

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Adam Bergman Karlsson; [2024]
    Nyckelord :Beamforming; Artificial Intelligence; AlphaZero; Radio Resource Management; Monte Carlo Tree Search;

    Sammanfattning : In accommodating the growing global demand for wireless, Multi-User Multiple-Input and Multiple-Output (MU-MIMO) systems have been identified as the key technology. In such systems, a transmitting basestation serves several users simultaneously, increasing the network capacity. LÄS MER

  3. 2. Evaluating intrusion detection points in an end-to-end solution

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Lilla Pankaczi; [2023]
    Nyckelord :RFID; Random UID; Mutual Authentication; Scyther;

    Sammanfattning : Evaluating all intrusion detection points in an end-to-end cyber-physical system can be challenging. This master thesis focuses on evaluating the security of the most exposed part of such systems, Radio Frequency Identification (RFID) communication. LÄS MER

  4. 3. Increasing energy efficiency of O-RAN through utilization of xApps

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

    Författare :Fredrik Borg; [2023]
    Nyckelord :telecom; o-ran; ric; xapp; radio access networks; energy efficiency;

    Sammanfattning : As 5G becomes more established and faces widespread roll-out, energy consumption of radio access networks around the globe will increase. Since the high-frequency radio waves used in 5G communication has a shorter effective range compared to the waves used in previous generations, 5G networks will require a higher number of radio units to compensate for their reduced range.

  5. 4. Automated Measurement of Relative HF Antenna Properties using WSPR

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

    Författare :Axel Blomqvist; [2023]
    Nyckelord :;

    Sammanfattning : The performance of antennas is an important factor in creating a well performing radio communication channel. Traditionally measuring High Frequency (HF) antennas is an expensive and complicated process. J. Zander[1] proposes an alternative method of evaluating antenna performances in the HF band. LÄS MER

  7. 5. Evaluating Thread network performance, locating and strengthening weak radio links

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Författare :André du Rietz; Elias Salo; [2023]
    Nyckelord :Internet of Things; IoT; Thread network; Evaluating Thread Network;

    Sammanfattning : In the fast-developing world we are living in, a tech phenomenon known as the Internet of Things (IoT) has taken hold. It has seen a lot of development over the past few decades, and today there are an estimated 30 billion IoT devices active. IoT is a machine-to-machine network that senses the world with the help of sensors. LÄS MER
