Policy choices can help keep 4G and 5G universal broadband affordable
通过量化需求侧收入与供给侧成本的关系，评估发展中国家实现2030年普遍宽带目标的可行性，发现有利的监管环境可将成本降低近一半，避免公共补贴。
The UN Broadband Commission has committed to universal broadband by 2030. But can this objective really be affordably delivered? The aim of this paper is to assess universal broadband viability in the developing world, quantifying the relationship between demand-side revenue and supply-side cost. A comprehensive scenario-based simulation model is developed open-source, capable of evaluating the global cost-effectiveness of different 4G and 5G infrastructure strategies. Utilizing remote sensing and demand forecasting, least-cost network designs are developed for eight representative Low and Middle-Income Countries (Malawi, Uganda, Kenya, Senegal, Pakistan, Albania, Peru and Mexico), the results from which form the basis for global aggregation via a new assessment framework. The cost of meeting a minimum ∼10 Mbps per user is estimated at USD 2 trillion using 5G Non-Standalone, approximately 0.67% of annual GDP for the developing world over the next decade. However, by creating a favorable regulatory environment, governments can bring down these costs by almost half – to USD 1.2 trillion (approximately 0.41% of annual GDP) – and avoid the need for public subsidy. Providing governments make judicious choices, adopting fiscal and regulatory regimes conducive to lowering costs, universal broadband may be within reach of most developing countries over the next decade.
