1. An apparatus comprising a transceiver operable to:

  • transmit, in a full power mode, a plurality of superframes, wherein the superframe comprises a plurality of data frames followed by a synchronization frame;

    transmit, in the full power mode, a synchronization signal;

    receive a message to enter into a low power mode;

    enter into the low power mode by reducing a power consumption of at least one portion of a transmitter;

    store, in the low power mode, at least one parameter associated with the full power mode operation wherein the at least one parameter comprises at least one of a fine gain parameter and a bit allocation parameter;

    transmit, in the low power mode, a synchronization signal; and

    exit from the low power and restore the full power mode by using the at least one parameter and without needing to reinitialize the transceiver.
