The number of IoT devices has been rising steadily for several years. While a few years ago IoT was still considered a buzzword, today almost every electrical device, from refrigerators to traffic lights, can be connected to the Internet via a corresponding IoT network. However, due to the steadily increasing number of network participants, their demands on the reliability and scalability of the underlying network infrastructure are also rising. In order to cope with the associated challenges,

Representatives of the latter approach are the LoRa and LoRaWAN standards. In order to give a first look at these technologies, this thesis deals with the characteristics of the standards and points out possible challenges of the technologies. This work therefore aims to address the question of the extent to which reliable and scalable network infrastructures can be created with the help of LoRa and LoRaWAN. The basis for this is formed by various test series and research work in the context of the technologies. To better differentiate between LoRa and LoRaWAN, the physical layer and the protocol layers above it are considered separately.
