✦ Abstract—This paper shows experimentally that standard wireless networks which measure received signal strength (RSS) can be used to reliably detect human breathing and estimate the breathing rate, an application we call " BreathTaking ". We show that although an individual link cannot reliably detect breathing, the collective spectral content of a(More)
—Measurements of received signal strength (RSS) on wireless links provide position information in various localization systems, including multilateration-based and fingerprint-based positioning systems, and device-free localiza-tion systems. Existing localization schemes assume a fixed or known transmit power. Therefore, any variation in transmit power can(More)
