    Sammanfattning : Revenue maximization for network operators is considered as a criterion for resource allocation in wireless cellular networks. A business model encompassing service level agreements between network operators and service providers is presented. LÄS MER

  3. 3. Energy Constrained Wireless Sensor Networks Communication Principles and Sensing Aspects

    Detta är en avhandling från Uppsala : Institutionen för teknikvetenskaper

    Författare :Erik Björnemo; Uppsala universitet.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless sensor network; communication under processing cost; wireless channels; fading; probability theory as logic; uncertainty; measurement capacity; TECHNOLOGY Information technology Signal processing; TEKNIKVETENSKAP Informationsteknik Signalbehandling;

    Sammanfattning : Wireless sensor networks are attractive largely because they need no wired infrastructure. But precisely this feature makes them energy constrained, and the consequences of this hard energy constraint are the overall topic of this thesis. LÄS MER

  4. 4. Design Space Exploration of Wireless Multihop Networks

    Detta är en avhandling från Göteborg : Chalmers tekniska högskola

    Författare :Urban Bilstrup; Högskolan i Halmstad.; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Wireless multihop networks; wireless sensor networks; Ad hoc networks; Design space; Wireless embedded networks; Packet radio networks;

    Sammanfattning : This thesis explores the feasible design space of wireless multihop networks and identifies fundamental design parameters. In the process of exploring it is important to ignore all details and instead take a holistic view. LÄS MER

  5. 5. Integrated Frequency Synthesis for Convergent Wireless Solutions

    Detta är en avhandling från Stockholm : KTH

    Författare :Jad G. Atallah; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wireless; transceiver; Bluetooth; DECT; GSM; 3G; LTE; WLAN; WiMAX; multi-standard; vertical handover; Sniffer; frequency synthesizer; phase-locked loop; PLL; sigma-delta; calibration; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Sammanfattning : Wireless transceivers combining several standards in one unit are of key importance. In order to reach the ultimate goal of maximizing the performance-to-cost ratio of such modules, a careful study of the target application, the architecture, and the frequency planning is strongly required.
