  • Effects of repeaters on UMTS network performance 
    Lähdekorpi, Panu (2006-03-08)
    AB3:Radioverkkosuunnittelijat pyrkivät suunnittelemaan matkaviestinverkon, jossa suorituskyky on mahdollisimman hyvä ja toteutuskustannukset mahdollisimman pienet. Työkalujen valinnalla ja huolellisella suunnittelulla on ...
  • Implementation aspects of RF-repeaters in cellular networks 
    Lähdekorpi, Panu; Isotalo, Tero; Usama Khan, Sultan; Lempiäinen, Jukka (2010)
    This paper discusses essential implementation aspects of simple amplify-and-forward type repeaters from the radio network planning point of view. Different RF-repeater configurations are assessed through numerical analysis ...
  • Improving HSDPA indoor coverage and throughput by repeater and dedicated indoor system 
    Isotalo, Tero; Lähdekorpi, Panu; Lempiäinen, Jukka (2009)
    The target of the paper is to provide guidelines for indoor planning and optimization using an outdoor-to-indoor repeater or a dedicated indoor system. The paper provides practical information for enhancing the performance ...
  • Optimization aspects for cellular service performance and mobile positioning in WCDMA radio networks 
    Borkowski, Jakub; Lähdekorpi, Panu; Isotalo, Tero; Lempiäinen, Jukka (2007)
    The aim of this paper is to evaluate the impact of selected topology planning aspects on performance of WCDMA cellular network and mobile positioning techniques. The assessment is based on field measurements and simulations. ...
  • Replacing terrestrial UMTS coverage by HAP in disaster scenarios 
    Lähdekorpi, Panu; Isotalo, Tero; Kylä-Liuhala, K.; Lempiäinen, Jukka (2010)
    This paper discusses the use of high altitude platforms, HAPs, to provide mobile communication services to on-ground customers. The paper explains the behavior of UMTS radio network in a situation, where the service is ...
  • RF-Repeater Performance Assessment and Planning Guidelines for WCDMA Networks 
    Lähdekorpi, Panu (2012-06-08)
    Although repeaters have been used and studied in some extent in cellular mobile networks in the past, a clear need for comprehensive system level analysis of repeaters exists. This thesis provides a thorough assessment ...
  • Utilization of an indoor DAS for repeater deployment in WCDMA 
    Borkowski, Jakub; Niemelä, Jarno; Isotalo, Tero; Lähdekorpi, Panu; Lempiäinen, Jukka (2006)
    The aim of this paper is to assess the applicability of a repeater connected to a distributed antenna system for improving indoor capacity in UMTS radio network. A guarantee of sufficient coverage and capacity for in-building ...
