    • Effect of adjacent-channel interference in IEEE 802.11 WLANs 

      García Villegas, Eduard; López Aguilera, M. Elena; Vidal Ferré, Rafael; Paradells Aspas, Josep (2007-06-03)
      Text en actes de congrés
      Accés obert
      Frequency channels are a scarce resource in the ISM bands used by IEEE 802.11 WLANs. Current radio resource management is often limited to a small number of nonoverlapping channels, which leaves only three possible channels ...

    • IPTV via WIFI per la Televisió Local de Vallirana 

      Sellart Ortega, Xavier (Universitat Politècnica de Catalunya, 2008-06-27)
      Projecte/Treball Final de Carrera
      Accés obert
      Realitzat a/amb:   Televisió de Vallirana
      La raó per la qual va sorgir aquest projecte es degut a que amb l’arribada del TDT, les televisions locals hauran de compartir canal. Per això, es van buscar alternatives per continuar tenint un canal independent, i així ...

    • New algorithm for distributed frequency assignments in IEEE 802.11 

      García Villegas, Eduard; Vidal Ferré, Rafael; Paradells Aspas, Josep (2007-02-28)
      Text en actes de congrés
      Accés obert
      The continuous growth of IEEE 802.11 wireless local area networks (WLAN) brings the benefit of a high speed wireless access to packet networks, such as Internet. But it also entails the successive appearance of new ...

    • Outdoor IEEE 802.11g cellular network performance 

      López Aguilera, M. Elena; Casademont Serra, Jordi; Cotrina Navau, Josep (Institute of Electrical and Electronics Engineers, 2004)
      Text en actes de congrés
      Accés obert
      Most studies about the performance of IEEE 802.11 are limited to a single cell environment. Nevertheless, the idea of designing an outdoor cellular network based on WLAN IEEE 802.11 is very attractive, due to the several ...

    • Wireless communication system for land seismic operations: A feasibility study 

      Ramos Gana, Ander (Universitat Politècnica de Catalunya, 2009-02-06)
      Projecte/Treball Final de Carrera
      Accés obert
      Wireless data networks have seen rapid growth and deployment in the recent years, replacing traditional wired data networks. WesternGeco is currently using a traditional wired data network in the land seismic operations ...
