Abstract: This paper aims to propose a three-dimensional (3D) point process model thatcan be employed to generally deploy unmanned aerial vehicles (UAVs) in alarge-scale cellular network and tractably analyze the fundamental network-wideperformances of the network. The proposed 3D point process is devised based ona 2D homogeneous marked Poisson point process (PPP) in which each point and itsrandom mark uniquely correspond to the projection and the altitude of eachpoint in the 3D point process, respectively. We study some of the importantstatistical properties of the proposed 3D point process and shed light on somecrucial insights into these properties that facilitate the analyses of aUAV-enabled cellular network wherein all the UAVs equipped with multipleantennas are deployed by the proposed 3D point process to serve as aerial basestations. The salient features of the proposed 3D point process lie in itssuitability in practical 3D channel modeling and tractability in analysis. Thedownlink coverage performances of the UAV-enabled cellular network are analyzedand found in neat expressions and their closed-form results for some specialcases are also derived. Most importantly, their fundamental limits achieved bycell-free massive antenna array are characterized when coordinating all theUAVs to jointly perform non-coherent downlink transmission. Finally, numericalresults are provided to validate some of the key findings in this paper.
