Abstract
In one embodiment, an apparatus comprises a transmitter to transmit a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols with each of the OFDM symbols having a first number of bytes; and a controller, coupled to the transmitter, to determine an initial fragmentation threshold value having a second number of bytes. The controller is operable to increase the second number of bytes to generate an aligned fragmentation threshold value having an aligned number of bytes approximately equal to a multiple of the first number of bytes. The apparatus further includes a fragmentation module to fragment a data frame into a plurality of fragments in response to the aligned fragmentation threshold value.
