Aspects of a method and system for communicating via a frequency shifting repeater are provided. In this regard, a signal having a first frequency may be received, the received signal may be quadrature down-converted by mixing it with a pair of phase-quadrature local oscillator (LO) signals, the down-converted signals may be up-converted by mixing them with the LO signals, and the up-converted signals may be added or subtracted to generate a signal, having a second frequency, for transmission. In this manner, a wireless communication range may be extended by repeating the received signal on a different frequency than at which it was received. The frequency of the LO signals may be based on a desired difference between the first and second frequencies, a frequency at which a target device receives signals, and/or noise present. |
