   Author : Voravit Tanyingyong; Peter Sjödin; Markus Hidell; Raimo Kantola; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network architecture and design; Network communications; Performance; Availability; Scalability; Internet of Things IoT ; Nätverksarkitektur och design; nätverkskommunikation; prestanda; tillgänglighet; skalbarhet; sakernas internet IoT ; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Advancement in technologies brings about new demands and services. In parallel, modern commodity off-the-shelf (COTS) hardware has become very capable yet affordable. It is often used in combination with Free/Libre and Open Source Software (FLOSS) to build open networking platforms, which offer alternatives to commercial network devices. READ MORE

4. 2. Optimizing Energy Efficiency in Wireless Links Through Reconfigurable Intelligent Surfaces and Optimal Ratios

   Author : Anders Enqvist; Emil Björnson; Ozlem Tugfe Demir; Cicek Cavdar; Yuanwei Liu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 6G; Energy Efficiency; Reconfigurable Intelligent Surfaces; 6G; energieffektivitet; rekonfigurerbara intelligenta ytor; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : This thesis explores the optimization of energy efficiency (EE) in the radiolink of wireless communication systems, focusing on both the user equipment (UE) and the base station (BS). The first part of the study examines strategies to minimize the energy consumption of the UE when transmitting short data payloads, utilizing a reconfigurable intelligent surface (RIS) controlled by the BS, to improve the channel conditions.

6. 4. Advanced Antennas in Wireless Communications : co-located & distributed

   Author : Afif Osseiran; Ben Slimane; Andreas F. Molisch; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

   Abstract : In a wireless radio network system, with an evolving standard, there is a need to increase system capacity due to the increase in the traffic demands, the higher data rate usage, and the need to further extend the coverage of the system. One possible solution is to use multiple antennas (co-located or distributed) for the radio links. READ MORE
