1. A method of increasing transmission performance between a tire pressure monitoring sensor and a receiver in a vehicle, the method comprising:

  • receiving a plurality of frames to be transmitted, each of the plurality of frames being separated by a first inter frame timing distance;

    determining an averaging factor for each of the plurality of frames, and a worst case averaging factor;

    determining a second inter frame timing distance that separates each of the plurality of frames, the second inter frame timing distance being less than the first inter frame timing distance;

    assembling the frames into a transmission burst and separating these frames with the second inter frame timing distance;

    inserting an additional frame into the transmission burst;

    transmitting each of the frames of the transmission burst with the worst case averaging factor.
