The world is moving to 5G technology where MIMO, small cell technology places a vital role. There is a linear relationship between generations and total power consumed. The capacities, speed of the data rate are the parameters for the upcoming generations which consume more power. Gupta, A., & Jha, R. K. Stated that, to improve the cellular energy efficiency, network topology must be densified and a combination of two densification approaches namely “massive” multiple-input multiple-output (MIMO) base stations and small cell access points are analysed in this paper[1]. The proposed Network Architecture reduces the traffic to the main base station and improves Quality-of-Service (QoS) to each user thus reducing power consumption. We have also performed simulations which show how the power consumption can be reduced by combining MIMO and small cells.
