“…The results show that a microwave-based approach always offers lower TCO than a fiber-based. A more extensive TCO analysis is proposed in [11,12], where the authors compared the deployment cost of wireless and fiber (point-to-point (PtP) and passive optical network (PON) options) transport technologies. The work in [11] focuses on the backhaul segment of a fixed-wireless access use case.…”

“…The work in [11] focuses on the backhaul segment of a fixed-wireless access use case. In contrast, the authors in [12] considered a general 5G mobile network and the TCO implication of using an HLS option for the TN segment. Their results show that microwave gain depends on the cost of fiber deployment and microwave equipment.…”

“…The TCO analysis of different technologies and the choice of the best functional split option have always gained interest from academia and industry. Some works focus on the TCO analysis of fiber and/or microwave architectures given a specific functional split option [8][9][10][11][12]. On the other hand, the works in [13,14] investigate the TCO of different fiber and microwave architectures when the functional split option is varied.…”

<p>One of the challenges for network operators is to design and deploy cost-efficient transport networks (TNs) to meet the high capacity and strict latency/reliability requirements of today’s emerging services. Therefore, they need to consider different aspects, including the appropriate technology, the level of reconfigurability, and the functional split option. A crucial aspect of network design is assessing the impact of these aspects against the total cost of ownership (TCO), latency, and reliability performance of a given solution. For this reason, this paper proposes a framework to investigate the TCO, latency, and reliability performance of a set of fiber and microwave-based TN architectures. They are categorized based on their baseband functional split option and the reconfigurability capabilities of the equipment used. Results show that in most of the considered scenarios, a microwave-based TN exhibits lower TCO than a fiber-based one. The TCO gain may vary with the choice of the functional split option, geo-type, reconfigurability features, fiber trenching costs, and cost of microwave equipment. Finally, it was found that the considered fiber and microwave architectures have almost similar average latency and connection availability performance and are suitable to meet the service requirements of 5G and beyond 5G scenarios.<br> </p>
