Design and Evaluation of mmWave MIMO Networks Using 28 and 60 GHz in Urban Areas
Keywords:mmWave, MIMO, 5G technology, evaluation, performance
A new alternative network is critical since cellular users are increasing year after year and network capacity is becoming insufficient. Currently, network design prioritizes not only performance but also energy efficiency. The MIMO system has existed for a long time and has been shown to improve system performance. A mmWave technology is currently one of the 5G enabling technologies that use high frequencies to enable speeds of up to 1 Gbps while maintaining high capacity and low latency. Thus, the combination of mmWave technology and MIMO systems is one of the challenges for implementing 5G technology with high performance and energy efficiency in urban areas. This paper, therefore, designs and evaluates the mmWave MIMO network using 28 and 60 GHz frequencies in urban areas, especially in Banda Aceh city. Then, this paper analyzes the designed network performance by considering coverage area, SINR, throughput, and energy efficiency. The designed mmWave MIMO system uses different antennas: 4, 8, 16, and 32. Simulation results indicate that the mmWave MIMO 28 GHz network has a larger coverage area, higher SINR, and more energy efficiency than the mmWave MIMO 60 GHz network. The highest energy efficiency is achieved in the network using a 16-antenna. On the other hand, the throughput of a mmWave MIMO 28 GHz network is lower than that of a mmWave MIMO 60 GHz network. The mmWave MIMO 28 GHz network has demonstrated advantages that make it ideal for use in urban areas, particularly in Banda Aceh.
