  1. 1. Design and Implementation of an Efficient Intrusion Response System for 5G RAN Baseband Units

    Master-uppsats, Linköpings universitet/Databas och informationsteknik

    Författare :Mirna Ghazzawi; Adil Imran; [2023]
    Nyckelord :Intrusion Response System; Security; OSSEC; Radio Access Network; Baseband Units;

    Sammanfattning : The 5G Radio Access Network (RAN) is a critical system that must be secured against potential attacks, particularly its Base-Band Unit (BBU), which is a common target for intrusions. Ericsson, which is a big provider of such systems, has placed significant emphasis on implementing Intrusion Detection Systems (IDS) to detect threats. LÄS MER

  3. 2. Development of a C-RAN Fronthaul Simulator

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

    Författare :Noel Tesfalidet; Sam Khosravi; [2023]
    Nyckelord :5G; Fronthaul; functional split; C-RAN; simulation; optimization; Digital twin; 5G; Fronthaul; funktionell uppdelning; C-RAN; simulering; optimering; Digital tvilling;

    Sammanfattning : Cellular networks have significantly transformed the way we communicate and access data and the data rates have only been increasing for the last 30 years. 5G is the current generation of cellular networks and enables faster data rates and lower latency. LÄS MER

  4. 3. Performance Analysis Of Massive MIMO With Port Reduction

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

    Författare :Tingrui Zhang; [2022]
    Nyckelord :5G NR; Massive MIMO; Fronthaul; Beamforming; Functional split; 5G NR; Massive MIMO; Fronthaul; Beamforming; funktionell uppdelning;

    Sammanfattning : In centralized radio access network (C-RAN) architecture, the base-band unit (BBU) is connected to one or more remote radio units (RRUs) via a fronthaul (FH) interface. Upgrading base station antennas in C-RAN to support massive multiple-input multiple-output (MIMO) technology can improve network spectral efficiency and largely boost the capacity of the 5G system.

  5. 4. Quantization Noise Shaping for LTE Fronthaul Downlink

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

    Författare :Alaa Mahamda; Veereswari Kalyanasundaram; [2017]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The modern mobile networks such as the Cloud Radio Network Access (C-RAN) are developing to deal with upcoming requirements in the current generation $4$\textsuperscript{th} Generation (4G) and the upcoming generation i.e. the $5$\textsuperscript{th} Generation (5G). LÄS MER

  7. 5. Interplay between capacity and energy consumption in C-RAN transport network design

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Huajun Wang; [2016]
    Nyckelord :C-RAN; Energy Efficiency; Fronthaul; Power Model; Baseband Splits; Fronthaul Network;

    Sammanfattning : Current mobile network architecture is facing a big challenge as the traffic demands have been increasing dramatically these years. Explosive mobile data demands are driving a significant growth in energy consumption in mobile networks, as well as the cost and carbon footprints [1]. LÄS MER
