Coverage & Ergodic Capacity Analysis in Downlink Dense Aerial Networks With Frequency Reuse

Recent advancements in wireless technologies beyond 5G have brought a significant surge in user traffic demands and heightened expectations for reliability. To meet the requirements, the base stations must transition to densified configurations. Conventional terrestrial networks are primarily designed for populated areas, leaving underserved regions such as overcrowded areas, disaster zones, and sparsely populated areas with inadequate coverage. In response to these challenges, aerial networks have emerged as a crucial adaptable deployment strategy. Unfortunately, due to the 3D deployment of aerial networks, coverage and rate analysis carried out for cellular networks are found to be inadequate and intractable. This paper presents a 3D model of aerial networks conceptualizing a hemisphere with frequency reuse, where aerial base stations are distributed as independent Poisson point processes with thinning to facilitate tractability. The proposed model uses frequency reuse to expand coverage while maintaining the trade-off with average capacity for the target user demographic. This paper presents a closed-form analysis for coverage and average capacity in dense aerial networks for downlink.
