Capacity Bounds Analysis of 5G networks in different propagation environments

Due to a propagation phenomenon caused by reflection and diffraction in the radio channel of wireless networks, the transmitted signal is received by the receiver with multiple copies and different amplitudes, delays, and arrival angles. Compared to 4G, 5G networks provide massive applications with higher data rates, higher speed, low latency, and maximum capacity. Therefore, the strengths of the signal are a major issue to be considered for such systems. Not much research in the literature focused on deriving the capacity bounds in different propagation environments taking into account different types of environments. Therefore, it is crucial to study the capacity bounds of these systems in more realistic environments as the free space model does not take into account the environmental obstacles. Based on the above, the capacity bounds are derived due to cell interference and limited uplink power, and the performance of 5G networks in different propagation environments using the extended COST-231 Hata model, is studied in this paper. The capacity bounds are derived and the performance is evaluated in different environments for path loss evaluations and system capacity. The provided numerical results reveal the fact that system capacity and coverage are mainly affected by the type of environment and the service factor values. Consequently, the provided investigations and analysis provide key indicators for mobile operators to consider in the future planning of 5G networks.
