Systems/methods of frequency variability responsive to a size of data to be transmitted

Embodiments of systems/methods are disclosed wherein a transmitter is configured to wirelessly communicate with a destination device by transmitting to the destination device a first plurality of subcarriers using a first set of frequencies and, responsive to a size of data that is to be transmitted to the destination device, transmitting to the destination device a second plurality of subcarriers using a second set of frequencies. According to some embodiments, the first set of frequencies and/or the second set frequencies comprise frequencies that are used for cellular communications and at least some frequencies of the second set of frequencies are mutually exclusive with the first set of frequencies.
