Localization is an important subject of the Internet of Things (IoT). However, GPS localization uses a lot of battery and cannot be used in most low-power applications.

Low Power Wide Area Networks are novel cellular connections which emerge with certain advantages. One of them is the possibility to perform an active triangulation for determining the position of a node.
