1. 1. Seamless Millimeter-wave Connectivity via Efficient Beamforming and Handover

   Författare :Sara Khosravi; Marina Petrova; Jens Zander; Riku Jäntti; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave networks; Beamforming; Handover; Reinforcement learning; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Extremely high data rate demands, and the spectrum scarcity at the microwave bands, make the millimeter wave (mmWave) band a promising solution to satisfy the high data rate demands in wireless networks. The main advantage of moving to the mmWave spectrum is the availability of large bandwidth. LÄS MER

3. 2. Location-aided Beam Alignment and Handover in Millimeter-wave Networks

   Författare :Sara Khosravi; Marina Petrova; Jens Zander; Sofie Pollin; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Millimeter wave networks; beam alignment; Handover; Reinforcement learning; Millimetervågnätverk; strålinriktning; överlämning; förstärkningsinlärning;

   Sammanfattning : Ever-increasing data rate demands in mobile networks and the spectrum scarcity at the microwave bands have resulted in the exploration of millimeter-wave (mmWave) frequencies for the next generation of wireless networks. While mmWave frequencies offer large bandwidth, communication at these frequencies is not straightforward due to the challenging propagation characteristics. LÄS MER

4. 3. Latency Reduction for Soft Real-Time Traffic using SCTP Multihoming

   Författare :Johan Eklund; Anna Brunström; Thomas Dreibholz; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transport protocol; SCTP; multihoming; latency; performance evaluation; failover; concurrent multipath transfer; scheduling; mobility; handover; Computer Science; Datavetenskap;

   Sammanfattning : More and more so-called soft real-time traffic is being sent over IP-based networks. The bursty, data-limited traffic pattern as well as the latency requirements from this traffic present challenges to the traditional communication techniques, designed for bulk traffic without considering latency.

5. 4. Communication and Patient Safety : Transfer of information between healthcare personnel in anaesthetic clinics

   Författare :Maria Randmaa; Maria Engström; Gunilla Mårtensson; Christine Leo Swenne; Hans Rutberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anaesthesiologist; anaesthetic clinic; communication; handover; incident reports; information transfer; interruption; memory; nurse; operating theatre; patient safety; post-anaesthesia care unit; safety attitudes; SBAR; Caring Sciences; Vårdvetenskap;

   Sammanfattning : Communication errors are frequent during the perioperative period and cause clinical incidents and adverse events. The overall aim of the thesis was to study communication – the transfer of information, especially the postoperative handover – between healthcare personnel in an anaesthetic clinic and the effects of using the communication tool SBAR (Situation-Background-Assessment-Recommendation) from a patient safety perspective.

7. 5. Improving User Experience of Internet Services in Cellular Networks

   Författare :Annika Klockar; Brunström Anna; Patrik Arlos; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Internet; cellular networks; wireless; TCP; ARQ; handover; queuing; CoMP; application utility; user selection; scheduling; fairness; Datavetenskap; Computer Science;

   Sammanfattning : The Internet has grown enormously since the introduction of the World Wide Web in the early 90's. The evolution and wide spread deployment of cellular networks have contributed to make the Internet accessible to more people in more places. The cellular networks of today offer data rates high enough for most Internet services. LÄS MER
