  3. 2. Analysis of the Performance of Different DWDM FilterTechnologies for Mobile Fronthaul Applications

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

    Författare :Fredrik Ahlbom; [2016]
    Nyckelord :DWDM; mobile fronthaul; C-RAN; AWG; TFF; Interleaver; DWDM; mobile fronthaul; C-RAN; AWG; TFF; Interleaver;

    Sammanfattning : In recent years, several studies and simulations have been made on changing the current Radio Access Network (RAN) architecture into a more centralized access network where the base band processing is done in a central oce (CO) instead of out by the antenna site. This new architecture is denoted as the mobile fronthaul and is planned to be in use for the coming 5G network. LÄS MER

    Nyckelord :Heterogeneous networks; mobile backhaul; network dimensioning; ultra-dense networks; moving networks; dynamic network resource allocation; fronthaul backhaul architectures;

    Sammanfattning : Mobile data traffic is expected to increase substantially in the coming years, with data rates 1000 times higher by 2020, having media and content as the main drivers together with a plethora of new end-user services that will challenge existing networks. Concepts and visions associated with the ICT evolution like the network society, 50 billion connected devices, Industrial Internet, Tactile Internet, etc. LÄS MER

  5. 4. Evaluation of Load Balancing Algorithms in IP Networks : A case study at TeliaSonera

    Uppsats för yrkesexamina på grundnivå, Institutionen för teknik och naturvetenskap

    Författare :Emil Hasselström; Therese Sjögren; [2005]
    Nyckelord :Technology; Load balancing; Traffic engineering; MPLS; OD Matrix; Simulation; TEKNIKVETENSKAP;

    Sammanfattning : The principle of load balancing is to distribute the data load more evenly over the network in order to increase the network performance and efficiency. With dynamic load balancing the routing is undated at certain intervals. This thesis was developed to evaluate load balancing methods in the IP-network of TeliaSonera. LÄS MER

  7. 5. Konstruktion och byggnation av testfixtur för 10Gbit/s transpondermoduler

    Uppsats för yrkesexamina på grundnivå, Institutionen för teknik och naturvetenskap

    Författare :Henry Behnam; [2002]
    Nyckelord :Electronics; Testfixtur; Elektronik;

    Sammanfattning : This thesis for the Master of Science degree was performed at Solectron Corporation in Norrköping. The background for the thesis was a need to develop and build two test fixtures to automatize testing and adjusting of transmitter modules (TX-fixture) and receiver modules (RX-fixture) which are head devices in DWDM-systems.
