1. 1. 3D Modeling of Factory Scenarios for 5G Evaluations

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Haodong Zhao; [2023]
   Keywords : ;

   Abstract : 5G is a key enabler for a variety of use cases in smart manufacturing which requires communications with high reliability and low latency. In a dynamic industrial environment, objects such as machines, production lines, storage shelves, robotic arms, and automatically guided vehicles may cause fading and have a large impact on radio propagation.

3. 2. mmWave Coverage Extension Using Reconfigurable Intelligent Surfaces in Indoor Dense Spaces

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Zhenyu Li; [2023]
   Keywords : mmWave Communication; Reconfigurable Intelligent Surface; Ray Tracing; Indoor Dense Spaces;

   Abstract : Millimeter-wave (mmWave) is widely investigated for indoor communication scenarios thanks to the available rich spectrum. However, the shortened antenna size and the high frequency make mmWave extra sensitive to blockages. READ MORE

4. 3. Comparative Analysis and Development of Receivers for Drone Remote Identification

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Xiaolinglong Guo; [2023]
   Keywords : drone detection; remote identification; field test; wireless receiver; drönardetektering; fjärridentifiering; fälttest; trådlös mottagare;

   Abstract : Similar to a car’s license plate, the European Union Aviation Safety Agency (EASA) has released new regulations imposing the registration of drone operators and the broadcasting of the drone’s “digital license plate”, i.e., the drone Remote Identification (RID) in flight, which gives a new opportunity in drone surveillance.

5. 4. Machine Learning-based MIMO Indoor Positioning

   University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

   Author : Qiyi Chen; [2023]
   Keywords : Technology and Engineering;

   Abstract : The most widely used positioning system is Global Navigation Satellite System (GNSS), which uses traditional positioning techniques and cannot achieve satisfactory positioning performance in indoor scenarios due to Non-Line-of-Sight (NLoS) transmission. Fingerprinting is a non-traditional positioning technique that is robust to NLoS transmission in indoor scenarios. READ MORE

6. 5. Analysis and Measurement of Key Performance Indicators for MIMO Antennas

   University essay from Umeå universitet/Institutionen för fysik

   Author : Ossian Kynman; [2023]
   Keywords : MIMO; Diversity Gain; Capacity; Correlation; Fading;

   Abstract : Multiple-in multiple-out (MIMO) is a wireless communication technique where antenna arrays, at the receiver and transmitter, utilize signal multipath propagation to increase data throughput capacity. The unique benefits MIMO provides have over the last 20 years led to the steady increase in usage in both Wi-Fi and mobile networks. READ MORE
