“…Finally, the Fault management accounts for cost of repairing each failure that occurs in the backhaul network. More details about the TCO model for backhaul networks are available in the work presented in [4].…”

“…It combines the work of [6] and [4] by analyzing both the power consumption and the TCO value of different backhaul architectures in a Greenfield scenario. This allows new important considerations, with respect to the ones already discussed in [6] and [4]. Second, this paper presents and compares the power consumption and the TCO value of different migration options for backhaul networks in a number of Brownfield deployment scenarios.…”

“…Their results showed that point-to-point microwave is a costefficient technology to provide high backhaul capacity in short deployment times. Moreover, the authors in [4,8,11,12] assessed the Capital Expenditure (CAPEX) and Operational Expenditure (OPEX) of mobile backhaul networks in several Greenfield deployment scenarios. More specifically, paper [8] assessed the economic impact of fiber and microwave backhaul solutions in the presence of low and high wireless capacity demands, while paper [11] compared the cost of different backhaul deployments based on fiber and copper in a scenario where fixed broadband access is already provided using fiber to the node solutions.…”

“…These results show that copper-based backhaul networks can cost up to 70% less than fiber-based backhaul networks. Finally, papers [4,12] presented a TCO model for backhaul networks that includes a detailed CAPEX and OPEX breakdown. These studies concluded that there is a significant impact in terms of CAPEX during the first years of the wireless network deployments.…”

“…Currently backhaul networks are largely based on microwave, copper, and fiber. These technologies offer different advantages depending on the deployment scenario [4]. Fiber-based alternatives have a relatively high deployment cost (CAPEX) but provide long-term support in terms of offered capacity.…”

Heterogeneous networks (HetNets) have the potential to cater for the capacity requirements of mobile broadband services at reduced cost and energy consumption levels. One key aspect in HetNets is the role of the backhaul. More specifically, it is crucial for a mobile operator to understand the impact of specific technological and architectural upgrades in the mobile backhaul network on the capital and operational expenditure (i.e., CAPEX and OPEX). This paper proposes a comprehensive methodology that can be used to analyze the total cost of ownership of a number of backhaul options based on fiber, microwave, and copper technologies. The study considers both a Greenfield and a Brownfield scenario and takes into account the mobile broadband capacity requirements for the time period between years 2015 and 2025. From the results presented in the paper it can be concluded that even though microwave and fiber will be predominately used in the future, the possible migration paths leading to such fiber-and microwave-based backhaul scenarios might be different, depending upon factors such as spectrum and license costs, time to deployment, availability of equipment, and required quality of service levels.

Densely deploying small cells is an attractive solution to the explosion of network traffic. However, it is well known that backhaul is a major challenge limiting the improvement of network performance. In this article, we first introduce the characteristics of different wired or wireless backhaul technologies, including fiber, xDSL, sub‐6 GHz, microwave, and millimeter wave (mmWave). As the main performance factors, throughput, latency, energy efficiency, and cost models are analyzed to provide useful guidance for the selection and deployment of backhaul links. Next, we survey existing works on joint optimization of access and backhaul links. Base station (BS) association schemes and caching techniques are also studied for their importance to further improve backhaul performance. Finally, research challenges on backhauling for small‐cell networks are summarized to inspire future research directions.
