The 5G Ubiquitous Directional Communication Technologies of Public e-Health for Rural and Remote Areas

Unacceptably high investments are required into deployment of the optic core and energy consumption infrastructures for ubiquitous wide covering of the sparsely populated rural and remote (RRD) territories using the standard 5G broadband radio access network conventional techniques which characterized by centralized, i.e., base-centric, architecture with short, up to 2 km, cells ranges. As a perspective approach to provide in low-cost manner a ubiquitous 5G broadband connecting of the RRD areas, we recently proposed an extremely green and flexible device-centric (D2D) long-range Hypercell architecture with coverage range up to $50\div 100$ km. In this work, we continue our recent fundamental investigations of the extremely green long-range smart broadband 5G PHY technique leaning on Friis's and Kraus's models of the directed radio channels' and on the invariant spectral (ICSE) and power (ICPE) criteria approaches. Simultaneously, we develop a new directivity managing technique, using an opportunities of the radically distributed multifunctional medium access control 5G MFMAC “all-in-one” smart tools.
