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. Radar and sea clutter simulation with Unity 3D game engine

   University essay from Linköpings universitet/Programvara och system

   Author : Mikael Johnsson; Linus Bergman; [2023]
   Keywords : radar simulation; sea clutter simulation; game engine; Unity; ray tracing; compute shader; graphics programming; GPU; radarsimulering; sjöklottersimulering; spelmotor; Unity; strålspårning; compute shader; grafisk programmering; GPU;

   Abstract : Game engines are well known for their use in the gaming industry but are starting to have an impact in other areas as well. Architecture, automotive, and the defence industry are today using these engines to visualise and, to some extent, test their products. READ MORE

4. 3. 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

5. 4. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

   Author : Lukas Jonasson; [2023]
   Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

   Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

6. 5. Ray-tracing Based Investigations on the Deployment of RISs in Indoor Scenarios

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

   Author : Swaroop Divya Sai Prem Nambala; Dexin Kong; [2023]
   Keywords : Reconfigurable intelligent surface; RIS; optimization; Ray-tracing; Mixed integer linear programming MILP ; Complex impulse response; Wireless Insite.; Technology and Engineering;

   Abstract : Reconfigurable intelligence surface (RIS) is a promising candidate technology for future 6G wireless communication systems. In existing communication systems, the network operators are unable to control the propagation environment, which causes significant limitations on communication performance. READ MORE
