1. 1. Towards Affordable Provisioning Strategies for Local Mobile Services in Dense Urban Areas : A Techno-economic Study

   Författare :Ashraf Awadelkarim Widaa Ahmed; Jan Markendahl; Ki Won Sung; Jens Zander; Bogdan Timus; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The future mobile communication networks are expected to cope with growing local usage patterns especially in dense urban areas at more affordable deployment and operation expenses. Beyond leveraging small cell architectures and advanced radio access technologies; more radio spectrum are expected to be required to achieve the desired techno-economic targets. LÄS MER

3. 2. Feasibility and Performance of Dynamic TDD in Dense and Ultra-Dense Wireless Access Networks

   Författare :Haris Celik; Ki Won Sung; Jens Zander; Mehdi Bennis; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Meeting the seemingly never-ending increase in traffic over wireless networks presents a major challenge for future mobile network design. Given that much of the traffic is expected to be more time-varying and unpredictable, time division duplexing (TDD) is gaining increasing favorability in part thanks to its ability to better accommodate network-wide traffic variations.

4. 3. On the Performance of Dynamic TDD in Ultra-Dense Wireless Access Networks

   Författare :Haris Celik; Ki Won Sung; Jens Zander; Gustav Wikström; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The appetite for wireless high-data rate services is expected to continue for many years to come and drive the need for more capacity. Ultra-dense networks (UDNs) represent a paradigm shift where each base station (BS) serves only a few user equipments (UEs). LÄS MER

5. 4. On the Deployment of Large-Scale High-Capacity Wireless Systems with Secondary Spectrum Access

   Författare :Evanny Obregon; Jens Zander; Ki Won Sung; William Webb; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : The avalanche in mobile data consumption represents a big challenge for mobile networks operators and national regulators. This thesis focuses on finding additional spectrum to meet this demand in a cost-efficient way by considering shared spectrum access. LÄS MER

7. 5. Low-Power Secondary Access to the TV and Aeronautical Bands
