Abstract: This paper presents an analysis and Frame Error Rate (FER) results for an experimental study on different channel conditions and performance of IEEE 802.11a transceiver. This paper concentrates on both physical layer (PHY) and Medium Access Control (MAC). GNU Radio is one of the best open source Software Defined Radio (SDR) used for packet-based transceiver systems. To analyse the system, a data was transmitted and received as packets and evaluated FER performance of the system in the presence of Additive White Gaussian Noise (AWGN) over Rayleigh and Rician distributed fading channels. The data recovered was stored in Packet Capture (PCAP) format which is used to investigate networks with common network protocol analyser software like Wireshark. For implementing this transceiver, we used IEEE 802.11 blocks in GNU Radio. This implementation and simulation results gave a confidence to move a step forward towards real-time validation.
