The main objective is to design and implementation Wi-Fi MAC transmitter using Verilog. For the wireless communication in RF range IEEE 802.11 is one of the many standards available. IEEE 802.11b defines the Medium Access Control (MAC) layer for wireless local area networks. Wi-Fi MAC transmitter module is divided into 5 blocks I.e. data unit interface block, controller block, payload data storage block, MAC header register block, data processing block. In this paper, the authors are considering only two blocks i.e. payload data storage block, data processing block.
