Abstract
We study the feasibility of utilising the RF transceiver of a mobile device to establish some kind of situation awareness. Our results show that the analysis of channel characteristics can provide additional and sufficiently accurate context information. This situation awareness is cheap in the sense that it can be obtained from already ongoing communication in a network of nodes. In this paper we present results from a case study with several USRP software radios. We show how the presence, position and activity of persons in a room can be obtained exclusively from channel measurements.
