“…Not only must the TCO of the network be evaluated, but the economic viability of the project and possible socioeconomic effects of the implementation must be estimated. This research complements the concepts outlined in [52], [53] by considering demographic, geographic, and socioeconomic factors to define the ICT services and applications adapted to the population's needs in these regions. Although [52] is a relevant study on the deployment of 5G transport networks, its scope does not include the evaluation of specific aspects of rural and remote areas.…”

Expanding broadband services represents a significant challenge for broadband operators, especially in light of the requirements related to the total cost of ownership of these technologies. In the last few years, this expansion has advanced significantly, but it still represents a challenge that must be overcome since there is a need to provide low-cost services to rural communities in remote areas. Issues related to geographical location, the low income of residents, and the lack of public infrastructural facilities lead to a disadvantageous relationship between the potential revenue for operators and the high costs of deploying infrastructure. Although there are several research endeavors in the literature aimed at addressing how connectivity can be provided, they do not discuss systems that take account of the specific features of these regions or that have adapted services and network applications to meet the needs of these communities. Thus, using dimensioning systems for the total cost of network ownership and taking into account capital and network operating expenses, this study establishes a technical and economic framework for the deployment of broadband networks in rural and remote areas. It also applies economic feasibility analysis techniques designed to assist decision making by interpreting the effects of any financial investment made and estimating the expected profits of the broadband operators. We also recommend the use of socioeconomic indicators to predict the potential social impact of this framework on the development of these regions. We employ a case study to demonstrate the operational features of the planned framework. Based on real data obtained from a municipality located in the Brazilian Amazon region, we show that it is possible to reduce the cost of subscribing to broadband services for end-users by reducing deployment costs and thus ensure that access to digital services can be equitably obtained.INDEX TERMS Broadband services, rural and remote areas, total cost of ownership, feasibility analysis.

“…The standard approach for assessing the economics of cellular networks is in terms of the Total Cost of Ownership (TCO) under different deployment scenarios, including all infrastructure, energy and maintenance costs, as well as the potential leasing of both spectrum and fiber (Yaghoubi et al, 2018). There is a need to analyze a full range of deployment options, as a lack of planning prior to deployment can result in significantly higher costs, and greater inefficiency in energy consumption.…”

The roll-out of 5G infrastructure can provide enhanced high capacity, low latency communications enabling a range of new use cases. However, to deliver the improvements 5G promises, we need to understand how to enhance capacity and coverage, at reasonable cost, across space and over time. In this paper, we take a spatiotemporal simulation modeling approach, using industry-standard engineering models of 5G wireless networks, to test how different infrastructure strategies perform under scenarios of uncertain future demand. We use coupled open-source models to analyze a UK growth corridor, a system-of-cities comprising 7 urban areas, known as the Oxford-Cambridge Arc. We find that population growth has a marginal impact on total demand for 5G (up to 15%), as the main factor driving demand is the increase in per user data consumption resulting mainly from video. Additionally, the results suggest only limited justification for deploying 5G based purely on the need for more capacity. Strategies which reuse existing brownfield Macro Cell sites are enough to meet future demand for Enhanced Mobile Broadband, except in the densest urban areas. While spatio-temporal analysis of infrastructure is common in some sectors (e.g. transport, energy and water), there has been a lack of open analysis of digital infrastructure. This study makes a novel contribution by providing an open and reproducible spatiotemporal assessment of different 5G technologies at a time when 5G is starting to roll-out around the world.

“…With regard to the servicing of failures and the installation of the equipment, an average speed of 20 km/h was assumed during transport of the repair/installation teams to the point of failure or installation. In addition, for financial reasons, a cost unit was employed based on the price of an indoor small cell, which at the time when this study was carried out cost US$ 300 [Yaghoubi et al 2018].…”

Fifth generation (5G) cellular networks will be the key element of a society that is becoming increasingly interconnected and digitalized. Applications adopted in many social and industrial sectors will require from 5G networks higher standards of availability and reliability. These requirements are leading operators to plan the deployment of protection schemes in the backhaul layer. In this context, our aim is to employ simulation to assess in a technical and economic way different backhaul protection schemes based on passive optical network (PON). The results indicate that the use of protection can increase the viability of 5G networks based on a PON backhaul supporting a hybrid fronthaul with fiber and copper.
