Abstract
A radio frequency radiation shield device may comprise a receiver for detecting a near field radio frequency signal. The receiver may include one or more receiving antennas for target frequencies. The shield device may further comprise a signal processor that samples signal characteristics of a detected signal and determines a nullifying signal in response to detecting a signal characteristic of the detected signal on a receiving antenna meets a trigger threshold. The nullifying signal may comprise a modulated version of the detected signal. The shield device may further comprise a signaler for generating the nullifying signal. The shield device may further comprise a transmitter. The transmitter may include a transmitting antenna at target frequencies for transmitting the nullifying signal.
