A Multi-Layer Framework for Enhancing Satellite Connectivity in Remote and Rural Areas

Abstract

In this research paper, a multi-layer approach is proposed to improving satellite connectivity in remote and rural locations, where the average revenue per user, the strength of the power infrastructure, the backhaul quality, and the terrain are oftentimes not conducive to a profitable terrestrial broadband service. The study adopts a research-synthesis and design-science approach, incorporating recent peer-reviewed research on satellite communications, the 3GPP non-terrestrial networks (NTN), satellite Internet, rural broadband, direct to device connectivity, satellite IoT, and field deployments and integrating them with prevailing ITU guidance. The proposed architecture has six layers: space, transport, access, edge/service, energy, and governance, all of which are coordinated by a cross-layer orchestration function. The framework does not view satellite broadband as an alternative solution to terrestrial infrastructure; instead, it considers GEO, MEO, LEO, cellular, Wi-Fi, fixed wireless and IoT links as complementary technologies to be used depending on the need for latency, capacity, coverage, cost, reliability and local services. The paper suggests a hybrid, multi-connectivity model as the most suitable: fibre/microwave except where impractical; satellite should fill geographic and resilience gaps; local access networks group demand at community level. Three analytical tables compare orbital options, define the proposed framework and map use cases to performance requirements. The authors conclude that though technical integration is essential, the sustainable rural connectivity also needs renewable power, affordability of terminals, transparency of spectrum and licensing process, local maintenance capability, community involvement, cybersecurity, and outcome-based universal-service policy.
