OFDM is explained in some details, during this research, to highlight its general view, challenges, characteristics and routing. In addition, it analyses the advantages and disadvantages and then it is compared to FDM. A MATLAB simulation was developed using wireless network data to prove that OFDM increases the bandwidth of Ad hoc Networks.
