dc.description.abstractDemand for systems and technologies ensuring indoor localization or tracking of an object with high and stable accuracy is continuously increasing. Nowadays, there are exist several wireless technologies, for instance Bluetooth or Wi-Fi, which can be employed for indoor positioning. In the future, Long Range (LoRa), originally developed for long range communication with high link budget, can extend the family of these technologies. This paper focuses on the LoRa technology and its employing in the licence free 2.4,GHz band for Received Signal Strength Indicator (RSSI) based indoor localization. To measure and collect the values of RSSI, a simple measurement setup is proposed. The RSSI values are used to calculate the position of an object according to the principle of trilateration. Measurements are conducted in three different indoor environments for different signal configurations of LoRa. The recorded dataset is available online for future research purposes. The results, analysed in terms of localization accuracy, revealed good performance of LoRa. However, this performance is highly depending on the signal configuration of LoRa and on the position of nodes.en
