CassarÓ P., Potorti F., Barsocchi P., Girolami M., Nepa P. Lessons learned on device free localization with single and multi channel mode.

In this paper we concentrate on device-free RSS- based indoor localization methods, which have been the subject of intensive studies in the last few years. Specifically, the purpose of this paper is to assess the performance improvements of a Variance-based Radio Tomographic Imaging (VRTI) technique, when scanning various radio channels. We compare the perfor- mance of such technique compared with a VRTI configured with only single channel, the latter being the "minimum introduced interference" option. Moreover, in this paper we discuss in which application scenarios the multi-channel scanning technique is usable and appropriate. We describe how we configure the measurements campaigns to gather RSS values as well two indicative performance metrics, namely the mean square error and percentiles of the error distribution.
