High altitude platform stations as a component of non-terrestrial heterogeneous networks 4G/5G

One of the ways to solve the problem of creating a modern telecommunications structure in hard-toreach areas of the Arctic, Asia, Latin America and a number of other territories is the introduction of communication networks of a new type of non-terrestrial networks (NTN), using not only satellite communication networks (SCN), but also various aerial systems. This article discusses the use of high altitude platform stations (HAPS) as a part of the architecture of NTN networks, which are capable of providing users with a wide range of communication services even in the absence of modern terrestrial telecommunications infrastructure. The options of NTN architecture using HAPS is described, in which they can perform the functions of repeaters or cellular base stations. The calculation of the energy characteristics of various radio links that are a part of a communication network based on HAPS is given. The example of the Arctic shows the feasibility of the proposed solution of using HAPS as a part of NTN and its high efficiency.
