Abstract The article describes a non-invasive radio tomography system aimed at increasing the accuracy of tracking objects inside buildings. It uses electromagnetic waves with frequencies from ISM 2.4 GHz band, thanks to which it covers such communication protocols as Bluetooth, Wi-Fi and ZigBee. It is primarily intended to detect organic life forms such as humans. The result of its operation is 2D imaging in the form of a heat map.
