In the current scenario data traffic in the wireless communication world has been increased exponentially and the current technologies, used in fourth generation are not proficient to endow with the required capacity. Therefore they are losing their significance. Hence we have to move on new vibrant technologies to meet the rapidly escalating requirements of society and to provide sufficient bandwidth, low latency, and high data rate for reliable communication as well. In this paper technologies used in communication systems and proposed technology is portrait. Which starts from MIMO (Multiple input multiple output) systems to MIMO-OFDM (Orthogonal frequency division multiplexing) system in fourth-generation then Massive MIMO systems in 5G and Ultra massive MIMO system with Beamforming technology in 6G.

MIMO, OFDM, 6G, Beamforming, Ultra massive MIMO
