Design and analysis 5G mobile network model to enhancement high-density subscribers

Abstract

In order to obtain a high data rate that is commensurate with the growing demand for internet services, the fifth generation)5G) cellular networks will use the bandwidth beyond 6 GHz, called millimeters waves (mm-waves), to obtain a higher. The first phase (phase I) of the 5G network design for high user density, where the optimized microcells are deployed at carrier frequency 700MHz with 20MHz bandwidth. The second phase (phase II) of the design consists of the deployment of microcells which are operating at 3.6GHz with 100 MHz bandwidth; this phase is planned to cover 200000 users within the province. The third phase (phase III) of the design is represented by deployment of picocells, which are planned to operate at 26 GHz frequency and bandwidth 500 MHz; this phase is planned to cover 3,500,000 users within the province. Two types of modulation are adopted for the network (OFDM and 256QAM); the overall performance of the network is studied with regards to percentage of coverage, power overlapping ratio, frequency interference and the Quality of Service (QoS).
