1. A local oscillator (LO) circuit for facilitating repeating of a signal transmitted from a first station on a first frequency channel to a second station on a second frequency channel comprising the LO circuit:

  • a first tunable LO associated with the first frequency channel, the first tunable LO tunable in a first frequency range lower than a frequency of the first frequency channel;

    a second tunable LO associated with the second frequency channel, the second tunable LO tunable in a second frequency range higher than a frequency of the second frequency channel, the second frequency range different from the first frequency range; and

    a first converter circuit for down-converting the signal on the first frequency channel to a first intermediate signal having a first intermediate frequency, and for down-converting the signal on the second frequency channel to a second intermediate signal having a second intermediate frequency.
