  1. 21. Beamforming router as relay to increase 5G cell coverage

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Jhansi Dunuka; Nikolai Panagiotou; [2021]
    Keywords : Beamforming; MIMO; 5G; NR; Direction of Arrival; Relay;

    Abstract : The growing traffic and global bandwidth shortage for broadband cellular communi-cation networks has motivated to explore the underutilized millimeter wave frequencyspectrum for future communications. Fifth generation (5G) is the key to empow-ering new services and use cases for people, businesses, and society at large. READ MORE

  3. 22. Measurement of the Complex Permittivity of Phantoms for 5G/6G Compliance Tests

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : William Utriainen; Adel Alizadeh; [2021]
    Keywords : 5G; radiation; absorption; safety;

    Abstract : In late 2019, 5G, the next generation of networktechnology was first deployed. The first deployment covers onlya small part of the total data transfer needs. In order to increasedata transfer, the frequency band used, must be increasedtowards the millimeter wave.As the frequency band is increased, safety studies must be done. READ MORE

  4. 23. Machine Learning Based Beam Tracking in mmWave Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yizhan Yang; [2021]
    Keywords : Beam Tracking; Machine Learning; RNN; LSTM; Strålspårning; Maskininlärning; RNN; LSTM;

    Abstract : The demand for high data rates communication and scarcity of spectrum in existing microwave bands has been the key aspect in 5G. To fulfill these demands, the millimeter wave (mmWave) with large bandwidths has been proposed to enhance the efficiency and the stability of the 5G network. READ MORE

  5. 24. Millimeter-Wave Pencil Beam Leaky-Wave Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tom Eriksson; Erik Westberg; [2021]
    Keywords : Leaky-wave antenna LWA ; Continuous transverse stubs CTS ; Parallel plate waveguide PPW ; Dispersion;

    Abstract : Moving into higher frequencies, in occurrence withmodern applications, poses the issue of higher attenuation ofelectromagnetic waves, which in turn demand more directiveantennas. This paper proposes a directive antenna designoperating at 30GHz based on leaky-wave technology. Themodel consists of two main components. READ MORE

  6. 25. Reinforcement Learning-based Handover in Millimeter-wave Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jiarui Yang; [2021]
    Keywords : Wireless communications; mmWave networks; reinforcement learning; handover; Trådlös kommunikation; mmWave-nätverk; Reinforcement Learning; överlämning;

    Abstract : Millimeter Wave (mmWave) is a key technology to meet the challenge of data rates and the lack of bandwidth in sub-6GHz networks. Due to a high operation frequency, the mmWave network has unique channel characteristics and a relatively high pathloss. READ MORE
