1. 1. A Study on Data-driven Methods for Selection and Evaluation of Beam Subsets in 5G NR

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

   Författare :Nic Ekman; Ilias Theodoros Skordas; [2022]
   Nyckelord :5G; NR; telecom; telecommunications; ML; machine learning; algorithms; beam; widebeam; propagation; beamforming; subset; RAN; radio; radio environment; ericsson; Technology and Engineering;

   Sammanfattning : 5G New Radio is the next generation of mobile networks and it comes with promises of ultra-high speeds, ultra-high reliability and ultra-low latency. This has posed a challenge for the engineers entrusted with the task of finding solutions which could fulfil the specification, and as a result, some promising areas have received increased attention in recent years.

3. 2. Prestations jämförelse av single-page gentemot multi-page webbapplikation på mobila nätverk : En mätning av svarstider på olika mobila nätverk

   Kandidat-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

   Författare :Martin Karlsson; [2021]
   Nyckelord :Multi-page; single-page; AJAX; quality of service; m-commerce;

   Sammanfattning : Arbetet undersöker huruvida en traditionell multi-page applikation eller en AJAX baserad single-page applikation presterar bäst med hänsyn till quality of service där insamling och analys av svarstider nyttjas för att undersöka frågan. Arbetet specificerar vidare på M-commerce där mobila enheter uppkopplade mot mobila nätverk ligger ifokus. LÄS MER

4. 3. Privacy risks caused by the Swedish Police use of IMSI-catchers in a democratic society

   Master-uppsats, Högskolan i Skövde/Institutionen för informationsteknologi

   Författare :Karl Martin Stawe; [2021]
   Nyckelord :;

   Sammanfattning : For over a decade, the Swedish government has debated the Swedish Police Authority, starting now, the Swedish Police, usage of IMSI-catchers, without finding a solution that provides a formal statute that balances crime-fighting and caring for a natural person's integrity. By IMSI-catchers, the author of this paper refers to the man-in-the-middle attack device that, among other things, can listen to SMS and phone calls in plaintext. LÄS MER

5. 4. Hand over process in a simulationenvironmentChallenges with radio network planning in simulation environments

   Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Grim Moström; [2020]
   Nyckelord :;

   Sammanfattning : Quality of Service in Mobile Cellular Networks is an increasinglyimportant research field. Society is demanding higher datatransmission rates and better reception than ever before. As the generations of wireless protocols, e.g, 3G-5G, are going toward shigher data rates, their cell range, or reception area is however constantly decreasing. LÄS MER

7. 5. An intelligent gateway for LoRaWAN coverage extension

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Författare :Robert Olsson; [2020]
   Nyckelord :lora; LoRaWAN; multihop; routing; gateway; bidirectional;

   Sammanfattning : LoRaWAN is one of the most adopted low-power wide-area networks, which use theproprietary LoRa modulation developed by Semtech to provide high sensitivity at lowdata rates for long ranges. LoRaWAN providing coverage using single-hop gatewaysto thousands of end-devices (sensors) running on batteries. LÄS MER
