Abstract:
1. A mobile phone with wireless camera detection operating in detection or communication mode, comprising: an antenna; a first mobile phone filter, receiving signals from the antenna and outputting a first signal corresponding to a first bandwidth; a third filter, receiving signals from the antenna and outputting a detection signal corresponding to a detection bandwidth, corresponding to that used by a wireless camera; an oscillator, generating a corresponding frequency which is the difference between the middle values of a wireless camera's transmission bandwidth and a second bandwidth; a mixer, generating a second signal by mixing the detection signal and the corresponding frequency, wherein the second signal corresponds to the second bandwidth; and a signal processor, processing the first signal and the second signal selectively, enabling mobile communication using the first signal when in communication mode, and detecting the signal strength of the second signal when in detection mode.
