  1. 1. Modelling and Investigation of Control of a Power Infrastructure Resource Management System for a Radio Base Station : A study on sustainable power management for ICT infrastructure.

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

    Författare :Gustav Lenart; [2023]
    Nyckelord :Hybrid Dynamical Systems; Resource Management; Hybrid Automaton; Sustainable solutions for Wireless technology; Hybrid Dynamiska System; Resurshantering; Hybrid Automaton; Hållbara lösningar för trådlös teknologi;

    Sammanfattning : In order to minimize greenhouse gas emissions and operational cost related to the ICT-infrastructure the power management method of a Radio Base Station (RBS) or Base Transceiver Station (BTS) at Ericsson is studied and modelled. The major load demand at RBS’s are due to uplink and downlink data traffic. LÄS MER

  3. 2. Life Cycle Cost of Smart Wayside Object Controller

    Master-uppsats, KTH/Spårfordon

    Författare :Filipp Zarov; [2021]
    Nyckelord :railway signalling system; interlocking; hardware; Object Controller; Smart Wayside Object controller; Lifecycle Cost; renewable energy sources; järnvägssignalsystem; ställverk; hårdvara; Utdelar; SWOC; livscykelkostnad; förnybara energikällor;

    Sammanfattning : In a regional railway signalling system, object controllers are the devices responsible for controlling Track Side Equipment and act as interfaces for TSE with the interlocking computer and the Traffic control system. However, associated cabling (signal and power cabling) and civil works pose a major capital investment and it is a source of significant Capital and Operational expenses, particularly in rural areas, where accessibility andconnectivity to power grid and to the interlocking are a problem.

  4. 3. Model-Based versus Data-Driven Control Design for LEACH-based WSN

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Axel Karlsson; Bohan Zhou; [2020]
    Nyckelord :Wireless sensor network; mobile sink; LEACH; model predictive control; reinforcement learning; Deep Q-Networks; : Trådlösa sensor nätverk; LEACH; modellbaserad regulator; reinforcement learning; Deep Q-Networks;

    Sammanfattning : In relation to the increasing interest in implementing smart cities, deployment of widespread wireless sensor networks (WSNs) has become a current hot topic. Among the application’s greatest challenges, there is still progress to be made concerning energy consumption and quality of service. LÄS MER

  5. 4. LCS Capable GSM Network

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Tejas Oza; [2015]
    Nyckelord :;

    Sammanfattning : This thesis is about Location Based Services which intends to acquire the location of the mobile phone. The goal of our thesis project is to extend the Mobile Switching Centre and Base Station Controller with location based support which is a part of the Global System for Mobile Communications that follows the 3rd Generation Partnership Project standards and integrate with the Mobile Arts Home Location Register, Gateway Mobile Location Centre and Serving Mobile Location Centre.

  7. 5. CPU Load Control of LTE Radio Base Station

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Joachim Larsson; [2015]
    Nyckelord :CPU load control; system identification; PI controller; radio base station; overload protection; LTE; telecommunication;

    Sammanfattning : A radio base station (RBS) may become overloaded if too many mobile devices communicate with it at the same time. This could happen at for instance sport events or in the case of accidents. LÄS MER
