802.11 Reference Design: Frame Tx - Hardware

When the lower level MAC software is ready to submit a frame for wireless transmission it passes control to the wlan_mac_dcf_hw core in the FPGA. This core implements a state machine which adheres to the channel access timing requirements in the 802.11 DCF. The core will transmit the frame as soon as the DCF protocol allows and will return the result of the transmission to the MAC software.
