1. 21. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

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

   Author : David Anguiano Sanjurjo; [2020]
   Keywords : 5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

   Abstract : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.

3. 22. Bi-directional Low Pass Filter and Mixer Design

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

   Author : Sharath Thandava Murthy; Meshach Milon Paul Pear Pradeep Kumar; [2020]
   Keywords : Technology and Engineering;

   Abstract : This report presents the research and implementation of a bidirectional filter and mixer combination for the transceiver chain in 5G TDD equipment. The main objective of this project is to find a feasible design for mixer and low pass filter to reuse the same hardware blocks for both transmitter and receiver chain. READ MORE

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

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Grim Moström; [2020]
   Keywords : ;

   Abstract : 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. READ MORE
