In the digital economy, broadband networks are increasingly based on fibre optic cables, 4G and 5G mobile and IP transmission, optimized for data rather than voice traffic. This means that regulators have to establish new costing and pricing approaches for the broadband era.

Just as importantly, regulators have to make the transition from ex-ante to ex-post market intervention, so that investment and innovation can thrive.
