The spectral efficiency of the wireless network can be increased with the application of several overlapping yet normalized subcarriers for simultaneous transfer of data. Known as the Orthogonal Frequency Division (OFDM), this technique has been used in many wireline and wireless networks. Another very common technology today is Multiple Input Multiple Output (MIMO). It will increase network performance and/or use MIMO technology to make the transmission more efficient. This strategy of employing numerous antennas can be merged with OFDM to attain spectral efficiency and reliability at both ends of the communication network.This is often seen as an desirable option for designing and building the wireless networks for the next decade, requiring higher data transfer speeds. This paper discusses the essence of wireless technologies OFDM and MIMO, and provides a description of the combination MIMO-OFDM.
