Coexistence of LoRa and Wi-Fi in the RF band 2.4 GHz
Kaučiarik, Filip ; Miloš, Jiří (oponent) ; Polák, Ladislav (vedoucí práce)
This diploma thesis deals with the study of coexistence that can occur between the LoRa and Wi-Fi systems in the non-licensed 2.4 GHz ISM band. The theoretical part of this thesis focuses on the description of the physical (PHY) layer of both systems. There are also defined coexistence scenarios that can occur between LoRa and Wi-Fi systems in common radiofrequency (RF) bands. In the experimental part of this thesis, an appropriate laboratory workplace is proposed and realized to measure different coexistence scenarios between LoRa and Wi-Fi. The functionality of the proposed concept and the adopted measurement methodology are verified by a set of experimental measurements. Measurement results are evaluated and discussed in detail. Finally, a laboratory work for education purposes in the Laboratory of Mobile and Wireless Communications is prepared.

Subjektivní testy vlivu obsahu scény na prostorový efekt 3D obrazu a videa
Kaučiarik, Filip ; Kufa, Jan (oponent) ; Boleček, Libor (vedoucí práce)
Práca sa zaoberá štúdiou parametrov videosekvencií ktoré ovplyvňujú kvalitu obrazu pri sledovaní 3D snímkov a videí. Je zameraná na porovnávanie jednotlivých parametrov videosekvencie ktorými sú časová, hĺbková a priestorová dynamika a ich vplyvu na subjektívne testovanie a hodnotenie kvality zážitku 3D u respondentov. V práci je obsiahnutý aj popis návrhu testovacej sekvencie na základe rôznorodosti parametrov sekvencie a aj návrh subjektívneho testu. Bol určený tzv. absolútny parameter J pre dosiahnutie najväčšieho vplyvu objektívnych parametrov sekvencie na 3D efekt a komfort scény v rámci subjektívneho hodnotenia.

Coexistence Of Lora And Wi-Fi In The 24 Ghz Band
Kaučiarik, Filip
This paper deals with the study of coexistence between LoRa and Wi-Fi systems in the non-licensed 2.4 GHz RF bands. An appropriate laboratory measurement workplace is realized to measure the performance of LoRa on physical (PHY) layer level in terms of packet error ratio (PER). The functionality of the proposed concept is verified by a set of experimental measurements, where different coexistence scenarios are considered.
