This paper describes a solution based on the Long Range Wide Area Network (LoRaWAN) technology to geolocalise IoT modules such as wearables used from vulnerable groups. Through estimation of the behavior of a LoRaWAN channel and using trilateration and RSSI information, the localization of an IoT wearable can be obtained within a small range. Routing people in need is one of the use cases the above mechanism could be integrated so as to be able to be tracked by familiar people.1 aBouras, Christos1 aGkamas, Apostolos1 aKokkinos, Vasileios1 aPapachristos, Nikolaos  uhttps://telematics.upatras.gr/telematics/publications/iot-geolocation-performance-using-lorawan?language=el
