1. A wireless communication device comprising:
wireless communication circuitry; and
processor circuitry coupled to the wireless communication circuitry, the processor circuitry configured to cause the wireless communication device to:
divide a physical layer (PHY) communication frame into a plurality of fragments;
transmit, via the wireless communication circuitry, a first fragment of the plurality of fragments during a first time period, wherein energy emitted during transmission of the first fragment remains within a predetermined energy limit;
waiting, following transmission of the first fragment, for at least a predetermined interval during which no portion of the PHY communication frame is transmitted; and
transmit, via the wireless communication circuitry, a second fragment of the plurality of fragments during a second time period, wherein energy emitted during transmission of the second fragment remains within the predetermined energy limit.
