Diplomová práca sa zaoberá štúdiom a meraním koexistenčných scenárov bezdrôtových systémov LTE a LoRa v bezlicenčnom ISM pásme 2,4 GHz. Je definované spoločné rádiofrekvenčné pásmo, v ktorom tieto systémy môžu koexistovať. Navrhnuté meracie pracovisko umožňuje automatizované meranie definovaných koexistenčných scenárov. Využíva sa k tomu PC, profesionálne meracie prístroje a software MATLAB. Funkčnosť navrhnutého konceptu je overená rozsiahlymi meraniami. Dosiahnuté výsledky sú graficky spracované a detailne diskutované.
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.
