Description
Summary:Over the last decade, mostly in the urban areas, there is tremendous growth in the cellular traffic. The major concerns for cellular network operators nowadays is to deal with ever changing heterogeneity of users and high specification devices. Amidst upcoming technologies, this work illustrates the cellular networks based on massive MIMO (Multiple Input Multiple Output) and on small cells (SC) with both large and small-scale fading environment for signal propagation. The massive MIMO set up network is analyzed with N antennas at the centered macro BS (Base Station) offering services to U users at an instant in the MC (Macro Cell) with sub-6 GHz spectrums. The massive MIMO network is demonstrated with 8×8, 16×16, 25×25, 50×50, and 100×100 configurations. The SCs based cellular network is analyzed with 1 MC and 8 SCs increasing the number of serving users from 50 to 100. The set up network is analyzed with allocation of sub 6 GHz at the MC and mm-wave spectrum at the deployed SCs. The key performance metrics of the set up networks such as sum rate, average user throughput, and energy efficiency are evaluated. With massive MIMO set ups, the plotted result depicts boost in the network sum rate and energy-efficiency with increase in the number of antennas at the centered deployed BS and users in the cell. The SCs based set up also depicts boost in the network sum rate and energy-efficiency with increase in the number of users in the MC with 8 SCs.
