Investigation of massive MIMO in mmWave and Sub 6 GHz

mMIMO is a fundamental technique for improving the 5G network and its capacity. More antennas can be packed into a small area. mMIMO technique initially designed for sub-6 GHz frequencies along with millimeter-wave high-frequency range like-30 GHz to 300 GHz. Despite their basic similarities, their unique propagation behaviors, and their hardware features, Sub6GHz refers to two bands like mid-and low-frequency bands under 6GHz. mmWave refers to high-frequency like-30 GHz to 300 GHz. Sub-6GHz refers to low bands below 1 GHz, whereas mid bands extend from 3 GHz to 6 GHz and are not classified as "mmWave." While mmWave 5G networks are tremendously fast, their radius is severely limited. This research study attempted to investigate the evolution of Massive MIMO in mmWave and Sub 6 GHz, as well as antenna designs for 5G. This approach will be used to improve the evolution of mMIMO antennas. This paper investigates the efficiency of Massive MIMO in mmWave beamforming using simulation of MATLAB Software.
