Coexistence of LTE and LoRa in the 2.4 GHz ISM band
Potočňak, Martin ; Staněk, Miroslav (oponent) ; Polák, Ladislav (vedoucí práce)
This diploma thesis deals with the study and measurement of coexistence scenarios that can occur between the LTE and LoRa systems in the unlicensed ISM band 2.4 GHz. A common radio frequency band in which LTE and LoRa systems can coexist is defined. An appropriate laboratory measurement is proposed and realized, allowing automatized measurement of the defined coexistence scenarios. For this purpose, a personal computer, professional measurement equipment and software MATLAB are utilized. Functionality of the proposed concept is verified by extensive measurements. The obtained results are graphically shown and discussed in detail.
Měření přenosu v automobilu v pásmu milimetrových vln
Potočňak, Martin ; Blumenstein, Jiří (oponent) ; Kotol, Martin (vedoucí práce)
Cieľom práce je návrh uchopenia a posúvania vysielacej antény v automobile a meranie prenosu signálu pri zmenách rôznych parametrov: obsadenosť vozidla, poloha sedadiel, vzdialenosť antén. Vysielacia a prijímacia anténa bude tvorená otvoreným ústim vlnovodu. Prenos signálu bude meraný vektorovým sieťovým analyzátorom ZVA 67 od firmy Rhode&Schwarz.
Coexistence Between Lte And Lora Systems In The 24 Ghz Ism Band
Potočňak, Martin
This work deals with the study of coexistence scenarios that can occur between wireless systems LTE and LoRa in the 2.4 GHz ISM band. For this purpose an appropriate measurement setup is proposed and realized. The proposed concept enables to provide automatic measurements of the considered coexistence scenarios. It is achieved by the connection of the measurement devices with a switch, a personal computer (PC) and software MATLAB. Functionality of the realized measurement setup is verified by experimental measurements.
