Analýza rádiového rozhraní a signalizace v LTE a 5G NR

Abstract

This bachelor thesis is focused on 4G and 5G NR network signalling and it's analysis. The signalling itself in air environment between mobile device and transmitter is then captured in Keysight Nemo Outdoor Drive Test Solution tool. Data captured by Keysight Nemo Outdoor tool are analyzed afterwards. First of all, the work with Keysight Nemo Outdoor tool is described. The work description is followed by teoretical description of captured signalization. Captured data from 4G and 5G NR networks contain signalling of the first registration in mobile network and also signalling when data are transfered. This bachelor thesis includes two assignments for technical subject. Assignments are focused on 4G and 5G NR signalling. Results of analyzed signalling are included in conclusion.
