1. 11. Analyzing VoIP connectivity and performance issues

   Kandidat-uppsats,

   Författare :Mehenni Sadaoui; [2019]
   Nyckelord :VoIP; connectivity and performance issues; call quality; packet traces.;

   Sammanfattning : The appearance of Voice over IP (VoIP) revolutionized the telecommunications word, this technology delivers voice communications over the internet protocol (IP) networks instead of the public switched telephone network (PSTN), calls can be made between two VoIP phones as well as between a VoIP phone and an analog phone connected to a VoIP adapter [1]. The use of this technology gives access to more communication options compared to the conventional telephony but the users face different problems, mostly connectivity and performance issues related to different factors such as latency and jitter [2], these factors affect directly the call quality and can result in choppy voice, echoes, or even in a call failure.

   Nyckelord :DPI SQL;

   Sammanfattning : The use of the Internet has increased over the years, and it is now an integral part of our daily activities, as we often use it for everything from interacting on social media to watching videos online. Phone calls nowadays tend to use Voice over IP (VoIP), rather than the traditional phone networks. LÄS MER

4. 13. Utilizing Multi-core for optimized Data Exchange via VoIP

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Sohrab Azami Ghadim; [2018]
   Nyckelord :;

   Sammanfattning : In contemporary IT industry, Multi-tasking solutions are highly regarded as optimal solutions, because hardware is equipped with multi-core CPUs. With multicore technology, CPUs run with lower frequencies while giving same or better performance as a whole system of processing. LÄS MER

5. 14. Communication tool in virtual reality – A telepresence alternative : An alternative to telepresence – bringing the shared space to a virtual environment in virtual reality

   Uppsats för yrkesexamina på avancerad nivå, Mittuniversitetet/Avdelningen för informationssystem och -teknologi

   Författare :Marcus Ekström; [2017]

   Sammanfattning : Videoconferencing is one of the most common telepresence methods today and educational videos is rising in popularity among distance learners. Traditional videoconferencing is unable to convey gestures and mutual eye contact between participants. This study aim to propose a Virtual Reality telepresence solution using game engines. LÄS MER

7. 15. Scheduler Algorithms for MU-MIMO

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Wissam Moustafa; Richard Mugisha; [2017]
   Nyckelord :Scheduling; Beamforming; TDD; TM-8; SRS; Downlink; Round Robin; SU-MIMO; MU-MIMO.; Technology and Engineering;

   Sammanfattning : In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. LÄS MER
