This document discusses EU regulations and competition law in telecommunications. It covers the objectives and principles of regulation, including promoting universal access, preventing market power abuse, and optimizing resource use. Regulations were introduced to manage the transition from national telecom monopolies to international competition through liberalization, privatization, and competition policies. The effects have included more providers, modernized networks, new services, lower prices, and increased penetration. However, regulation has costs for operators and effects depend on the degree of reform in each country. The conclusion is that regulated competition is generally better for consumers and efficiency than monopoly or unregulated competition.
