Abstract:Infrastructure decision-making is challenging due to high levels of future uncertainty. Indeed, when considering broadband coverage, we are also faced with a situation where operators are reluctant to share data, there are few existing open-source evaluation models, and most available tools cannot be used by non-technical users. Transparency is sometimes low. Often disagreements arise between operators, regulators and other actors, with little independent assessment of key issues. Consequently, this paper proposes the development of a Digital Twin as a virtual test-bed for evaluating telecommunication policies. The concept of a Digital Twin has been common for several years in aerospace engineering, since first proposed by NASA in 2010. The vision defined in this paper is for a Digital Twin to be a virtual engineering-economic representation of a real-world telecommunication network, whereby simulation techniques allow exploration of potential future states under different policy conditions. A Digital Twin is developed for the British incumbent’s fixed broadband network, spanning 30 million premises and over 4.3 million geospatial telecommunication network assets. Using a network subset for Cambridgeshire, England the rollout of Fibre-To-The- Premises and Fibre-To-The-Distribution-Point upgrade options are then tested. Under different demand scenarios, market-based rollout is compared to a subsidised rollout strategy. Independently testing broadband deployment strategies in a virtual market and evaluating their effectiveness can provide greater transparency for decision-making processes. Over the long-term, a Digital Twin could help to generate new knowledge by testing experimental policy options, fostering greater innovation in how we tackle both perennial and emerging digital divide issues.
