The technical whitepaper “Optimising FTTH networks to enable Convergence” by the Deployment & Operations Committee of the FTTH Council Europe sheds light on the potential cost savings achievable through the integration of these networks.
In this article, we describe the unique benefits of FTTH broadband and 5G wireless technologies, and the convergence of these two powerhouses.
The European Push for Convergence
The FTTH Council Europe has broadened its horizons to encompass "fibre to the wireless antennas" for 5G. The initiative stems from a consolidated whitepaper that joins findings from studies conducted in 2019 and 2021. The overarching goal of these studies is to ensure Gigabit internet accessibility for all and widespread 5G availability by 2030, aligning with the European Digital Decade program's objectives.
The Cost-Benefit Analysis
The report, enriched by contributions from global FTTH Council organisations, zeroes in on the cost implications of constructing FTTH networks with varying spare capacities for 5G or other applications. The fusion of 5G technology not only supports mission-critical applications but also paves the way for future technological advancements.
As we venture further into the digital age, the proliferation of connected devices and their intercommunication will surge. That emphasises the necessity for a robust spectrum to facilitate wireless data transfer. While higher frequencies can handle vast data capacities, they face challenges when it comes to building penetration.
The solution lies in creating a network of small cells tethered to a fibre backhaul network, essential for 5G applications like smart cities, augmented reality, and autonomous vehicles. The infrastructure that can be integrated with Fibre-to-the-Home solutions.
Financial Implications of Convergence
Merging the infrastructures for 5G and FTTH can usher in heightened efficiency and cost reductions. As the fibre network convergence broadens its scope, it is imperative to assess its viability from both technological and business standpoints, especially given the cost disparities between urban and rural regions across countries. Strategically planning an FTTH network that is 5G-ready can harness synergies, optimising investment returns while minimising the need for extensive civil works.
Research by the FTTH Council unveiled that a combined FTTH/5G network could reduce costs by a staggering 65% to 96% compared to a standalone fibre backhaul for 5G. Further studies have highlighted the cost-saving potential of incorporating spare capacity during the initial deployment of a Fibre-to-the-Home network when subsequently introducing a Fibre-to-the-5G network.
Analysing the FTTH and 5G Convergence
The model offers a comprehensive Bill of Material and Bill of Quantity. A detailed list that enumerates all the required volumes to actualise the network, providing stakeholders with a clear picture of the resources needed. Moreover, fibre routes that interconnect sites with an existing FTTH network exhibit high convergence, hence leveraging existing FTTH infrastructure can further enhance the efficiency and cost-effectiveness of 5G integration.
A pivotal study by the FTTH Council underscores the value of incorporating spare capacity in current fibre networks for future 5G rollouts. While reserved spare capacity can lead to cost reductions in FTT5G, the precise amount hinges on uncertain variables, like the placement of future antennas.
Withing our thorough study, you will find further information on a model tailored for the deployment of fibre optic networks to bolster 5G technology, which contemplates diverse areas, scenarios, and factors, including network architecture, materials, and associated costs. The proposed network, designed with underground microducts and air-blown fibre cables, is adaptable to various future deployment needs.
The convergence of FTTH and 5G is a promising avenue, both technologically and economically. By leveraging existing infrastructure, optimising investments, and planning for future needs, stakeholders can ensure a seamless and cost-effective transition to a more connected future.
