  1. 1. The impacts of network effects and multi-service provision on consumer switching costs in the Swedish telecommunications market

    University dissertation from Chalmers University of Technology

    Author : Pratompong Srinuan; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nationalekonomi; Economics; Ekonometri; Econometrics; Telekommunikation; Telecommunication; Teknik och social förändring; Technology and social change; switching costs; termination-based price discrimination; calling clubs; tariff-mediated network effects; local network effects; broadband Internet; multiple-service; Sweden;

    Abstract : The Swedish telecommunications market has been liberalised since 1990s. Liberalisation gave an opportunity to several new entrants to enter to the market. Consumers also gained benefits from more telecom providers and services to choose from, and lower telecom prices. READ MORE

  2. 2. A flexible framework for detection of feature interactions in telecommunication systems

    University dissertation from Uppsala universitet

    Author : Gustaf Naeser; Uppsala universitet.; Uppsala universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Systems; Datorteknik;

    Abstract : The complexity of today's telecommunications systems grows with each new feature introduced. As the number of services an operator provides can be used to gain advantage over competitors the number of services will continue to increase. READ MORE

  3. 3. Human perception in speech processing

    University dissertation from Stockholm : KTH

    Author : Volodya Grancharov; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quality assessment; speech enhancement; postfilter; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Abstract : The emergence of heterogeneous networks and the rapid increase of Voice over IP (VoIP) applications provide important opportunities for the telecommunications market. These opportunities come at the price of increased complexity in the monitoring of the quality of service (QoS) and the need for adaptation of transmission systems to the changing environmental conditions.

  4. 4. Studies of Three Different Methods to Estimate the Up-link Performance of Mobile Phone Antennas

    University dissertation from Stockholm : Royal Institute of Technology (KTH)

    Author : Sathyaveer Prasad; Högskolan i Gävle.; Högskolan i Gävle.; KTH.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation; Antenna measurements; mobile phones; total radiated power; reverberation chamber; anechoic chamber; Telia Scattered Field Method; Maximum likelihood Estimator;

    Abstract : Antennas play an important role in determining the overall radio performance for wireless communications. If all other radio components perform according to their specifications, the performance of a mobile phone can be entirely determined by measuring the efficiency of its antenna. READ MORE

  5. 5. Digital Baseband Modeling and Correction of Radio Frequency Power Amplifiers

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Per Landin; KTH.; Högskolan i Gävle.; [2012]
