Abstract
The invention relates to an indoor localization system for a wireless communication network. The system comprises: one or more anchor devices, a central entity, and one or more tag devices. Transmission of signals by the one or more tag devices is controlled so that one signal is transmitted at a time on given radio resource, wherein the tag device transmitting said one signal is the tag device being localized. At least one anchor device is configured to: receive, the signal transmitted by the tag device being localized; determine an estimate of a direction of arrival (DOA) based on the received signal by applying a first power method-based algorithm and a second power method-based algorithm respectively and send the estimated DOA together with DOA metadata to the central entity. The invention relates also to indoor localization methods, an anchor device, a computer program, and a computer readable medium.
