“…In the case of MNOs, the most common and least worrisome type of sharing for policymakers is passive, but technologists and Industry consolidation through mergers and acquisitions o er an alternative approach for service providers to realize the economic benefits of network sharing. (Afraz et al, 2019;Motta and Tarantino, 2021;Oughton et al, 2022). An implicit assumption of the technical and economics literature that has examined network sharing has taken the perspective that the networks are provided by (legacy) service providers that own/manage the networks to deliver services to increasingly demanding and heterogeneous end-users.…”

Resource sharing is fundamental to the design of telecommunication networks. The technology, economic and policy forces shaping the transition to next-generation digital networking infrastructure—characterized here as “5G+” (for 5G and beyond)—make new and evolved forms of edge sharing a necessity. Despite this necessity, most of the economic and policy research on Network Sharing Agreements (NSAs) has focused on sharing among service providers offering retail services via networks owned and operated by legacy fixed and mobile network operators (MNOs). In this essay, we make the case for why increased and more dynamic options for sharing, in particular of end-user owned network infrastructure, should be embraced for the future of NSAs. Furthermore, we explain how such a novel sharing paradigm must be matched by appropriate regulatory policies.

“…One way that governments can improve the viability of investments to reduce the digital divide is by allowing infrastructure and resource sharing (Afraz et al, 2019;Hou et al, 2019;Maksymyuk et al, 2019;Meddour et al, 2011;Rebato et al, 2016;Samdanis et al, 2016;Sanguanpuak et al, 2019;Van der Wee et al, 2014). The standard presumption that each MNO in the market builds their own dedicated network is increasingly looking unviable, given the cost of delivery in rural areas and the fact revenue is now generally declining in many telecom markets.…”

In recognition of the transformative opportunities that broadband connectivity presents, the United Nations Broadband Commission has committed the international community to accelerate universal access across the developing world. However, the cost of meeting this objective, and the feasibility of doing so on a commercially viable basis, are not well understood. This paper compares the global cost-effectiveness of different infrastructure strategies for the developing world to achieve universal 4G or 5G mobile broadband. Utilizing remote sensing and geospatial infrastructure simulation, 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 aggregation to the global level. To provide at least 2 Mbps per user, 4G is often the cheapest option to reach universal coverage. The cost of meeting the UN Broadband Commission target of a minimum 10 Mbps per user is estimated at $1.7 trillion using 5G NSA, equating to approximately 0.6% 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 as much as three quarters -to $0.5 trillion (approximately 0.2% of annual GDP) -and avoid the need for public subsidy. Providing governments make judicious choices, adopting fiscal and regulatory regimes conducive to lowering costs, broadband universal service may be within reach of most developing countries over the next decade.
