Abstract:
IEEE 802.11 is a wireless LAN technology based on a cellular architecture where the system is subdivided into cells. Each cell is called Basic Service Set (BSS) which is controlled by a base station called Accesses Point (AP). Access points are connected through Distribution System (DS), typically Ethernet or wireless itself. Ethernet LAN Technology uses CSMA/CD protocol; these protocols are very effective when medium is not heavily loaded. In this paper, the Wi-Fi MAC transmit and receive protocol is implemented with Verilog HDL. The individual modules of the Wifi MAC Layer Transmit and Receive Protocol confirming to the IEEE 802.11 specification have been designed. The whole Wi-Fi Mac Layer Transmitter and Receiver are integrated. The various blocks and integrated blocks are simulated and functionality of each block is verified with test benches. Simulation results verify the correct functions of the designed Wi-Fi MAC transmit and receive protocol. The logic synthesis of the designed Wi-Fi MAC Layer Transmitter and Receiver is performed with Xilinx Synthesis Tools. Wi-Fi allows LANs (Local Area Networks) to be deployed without cabling for client devices, typically reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs. A Wi-Fi enabled device such as a PC, game console, mobile phone, MP3 player or PDA can connect to the Internet when within range of a wireless network connected to the Internet. Wi-Fi installations can provide a secure computer networking gateway, firewall, DHCP server, intrusion detection system, and other functions.
