1. 21. Link blockage modelling for channel state prediction in high-frequencies using deep learning

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

   Author : Shreya Krishnama Chari; [2020]
   Keywords : Radio link blockage; mmwave communications; sub-6GHz communications; 5G; Long short-term memory network; Deep neural network; Blockering av radiolänkar; mmwave-kommunikation; sub-6GHzkommunikation; 5G; Long short-term memory nätverk; Deep neural nätverk;

   Abstract : With the accessibility to generous spectrum and development of high gain antenna arrays, wireless communication in higher frequency bands providing multi-gigabit short range wireless access has become a reality. The directional antennas have proven to reduce losses due to interfering signals but are still exposed to blockage events. READ MORE

3. 22. PLL for 5G mmWave

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

   Author : Daniel Bakic; Jinzhuo Wu; [2020]
   Keywords : PLL; 5G-NR; RFIC; beamforming; 22nm FDSOI; charge pump; vco; loop filter; frequency divider; phase detector; phase noise; jitter; Technology and Engineering;

   Abstract : This paper presents research and implementation of a high frequency Integer-N phase-locked loop for digital beamforming in mobile devices. Multiple topologies investigated whereof two were implemented. The transient phase noise of the PLL is -104dB/-95dB @1MHz. The output frequency range is from 8G-10G. READ MORE

4. 23. Sequence Prediction for Identifying User Equipment Patterns in Mobile Networks

   University essay from KTH/Matematisk statistik

   Author : Theoharis Charitidis; [2020]
   Keywords : Markov chain; mobile networks; user equipment; machine learning; statistics; sequence prediction; stochastic process; Maskininlärning; mobila nätverk; statistik; markovkedjor; all k order markov; stokastisk process; sekvensprediktering;

   Abstract : With an increasing demand for bandwidth and lower latency in mobile communication networks it becomes gradually more important to improve current mobile network management solutions using available network data. To improve the network management it can for instance be of interest to infer future available bandwidth to the end user of the network. READ MORE

5. 24. An intelligent gateway for LoRaWAN coverage extension

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Robert Olsson; [2020]
   Keywords : lora; LoRaWAN; multihop; routing; gateway; bidirectional;

   Abstract : 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. READ MORE

6. 25. Smart Case for Remote Radio Kit

   University essay from Uppsala universitet/Fasta tillståndets elektronik

   Author : Emil Östlund; [2019]
   Keywords : CAD; LTE; IoT; Signal processing; Data communication; Data transmission; 3D printing; Soldering; Electrical circuit; schematics; simulations; Arduino; Software; Hardware;

   Abstract : The thesis aims to develop a prototype for a Smart Case for Remote Radio Kits at the department of Demo & Event at Ericsson in Kista.The smart case consists of a mechanical structure (the case itself with ) and an electronic system that includes a temperature sensor, a LCD display showing the temperature, a GPS (global positioning system) module for positioning the case, a GSM (Global System for Mobile Communications) module and a microcontroller Arduino UNO.
