The IEEE802.11a standard uses Orthogonal Frequency Division Multiplexing (OFDM). It can give information rate up to 54Mbps in Wireless Local Area Networks (WLANs). This standard is utilized as a part of indoor applications and also in vehicles i.e. versatile situations. In this paper, the authors assess Bit Error Rate (BER) by changing the quantity of pilots utilizing numerous adjustment plans, for example, BPSK, QPSK, 16QAM, 64QAM and 256 QAM. They likewise dissect the BER with shifting client speed. The general recreation has been performed utilizing MATLAB as the reproduction apparatus.
