1. An on frequency repeater for a wireless network, comprising:

  • a first antenna that is directed toward a first selected location in the wireless network to receive RF signals from said first selected location;

    an amplification chain coupled to the received signal and amplifying the level of the received signal to generate an amplified RF signal;

    a second antenna spaced apart from the first antenna and receiving and transmitting the amplified RF signal to a second location in the wireless network; and

    a feedback oscillation detection circuit coupled to the amplification chain in a gain control loop including a gain adjustment circuit and a gain control circuit, the feedback oscillation detection circuit detecting a saw tooth waveform in the gain control loop to detect onset of feedback oscillation between the first and second antennas.
