We present the design of a new passive communication method that does not rely on ambient or generated RF sources. Instead, we exploit the Johnson (thermal) noise generated by a resistor to transmit information bits wirelessly. By switching the load connected to an antenna between a resistor and open circuit, we can achieve data rates of up to 26bps and distances of up to 7.3 meters. This communication method is orders of magnitude less power consuming than conventional communication schemes and presents the opportunity to enable wireless communication in areas with a complete lack of connectivity.
