ABSTRACT:
A mobile phone with wireless camera detection. A mobile phone converts the frequency band of a received signal to mobile signal frequency band (for example GSM, DSC or PCS) with added mixer, oscillator, and filter. The converted signal is treated as a mobile signal prior to processing in the base band processor. Detected signal strength is checked to determine whether a wireless camera is currently present.
