1. A method to multi-mode phase track with shifting pilot tones, the method comprising:

  • receiving an orthogonal frequency division multiplexing (OFDM) transmission of a packet with pilot tones shifting locations between OFDM symbols;

    processing a preamble of the packet to determine whether the OFDM transmission comprises a one megahertz bandwidth or comprises a bandwidth of two megahertz or greater;

    setting a track intercept multiplier value to 0.2 if the OFDM transmission comprises a one megahertz bandwidth;

    determining phase rotations of the pilot tones based upon the track intercept multiplier value; and

    performing phase tracking based upon the phase rotations.
