Policy Challenges Relatively little full "infrastructure competition" has emerged in the fixed-line networks, except in very densely populated areas, where cable networks were already present, or where local authorities have been active. One of the key questions in light of the future connectivity needs is whether the current framework sufficiently promotes investments in the very highcapacity networks needed in the future, and sufficiently rewards the most farsighted network investments. At the same time, network investments should not be an objective per se, but rather the adoption and use of high-speed services by European end-users, who should benefit in terms of choice, price and quality. In addition, the difficult questions of how to cover the less densely populated areas and how to realise long-term public-interest objectives will need to be addressed. As regards fixed-line networks, the main regulatory tool is ex ante wholesale market regulation in order to enable market entry on competitive terms in both services and networks markets. It will be necessary to examine, inter alia, the extent to which this regime effectively drives investment in areas with different population densities, infrastructure presence and other economic characteristics; whether, in areas where infrastructure competition is very unlikely, competition to roll out the first very high-capacity network could be facilitated; and whether, in areas where infrastructure competition is conceivable, incentives for the highest capacity roll-out or upgrades should be enhanced for both historic incumbents and alternative operators. This could be done for example through a simplification of wholesale access products in the light of technology developments, a concentration of regulatory incentives on the highest-capacity NGA networks, or implementation of best practice regarding access to available passive infrastructure (e.g. ducts, poles). It would also be important not to affect the pro-competitive positive effects of the liberalisation, which have been achieved over the past years. The question whether universal service obligations can play a role must also be addressed, while recognising very different national situations. Regulatory fragmentation is also an unresolved issue. Although telecom markets have become more integrated, progress is slow and the provision of connectivity to business and consumers remains highly divergent across the Union. This is particularly the case for radio spectrum which is a vital building block for the deployment of wireless broadband services, especially mobile broadband. In light of the EU objectives beyond 2020, the Commission intends to evaluate the EU regulatory framework for spectrum management with regard to (a) the efficiency of allocation of spectrum throughout the internal market, to facilitate innovation and to underpin it with the benefits of economies of scale; and b) the authorisation of the use of radio spectrum for electronic communications and how it responds to the new connectivity needs and challenges. There has been an explosion in the demand for wireless connectivity for the purposes of Internet access, mobile, nomadic and fixed wireless data and new services within communications, transport, healthcare, and energy sectors. Spectrum supply is crucial for the Digital Single Market; spectrum-enabled services today are worth approximately €500 billion per annum – and up to approximately €1 trillion by 2023. However, many European citizens, especially in rural areas, are still deprived of access to wireless broadband services. Industry investments in fourth generation technologies started later than in some other developed regions, mainly due to delays in the granting of authorisations to use spectrum. Although the great majority of Europeans (79%) are now able to access 4G networks, this is still a paltry 27% in rural areas. As stressed by the Commission in the recent Digital Single Market Communication, electronic communications markets predominantly remain national, regional or even local in scope, which forces operators to develop national strategies even when offering comparable wireless services in several Member States. Significant differences remain with regard to approaches to spectrum governance and strategies to make spectrum available which cannot be justified solely by differing national circumstances. These differences may hinder investment and innovation in business, restricting the full potential for economies of scale in an EU-wide market for today's and tomorrow's spectrum-enabled services. In addition, telecoms operators compete with services which are increasingly seen by endusers as substitutes for traditional electronic communications services such as voice telephony, but which are not subject to the same regulatory regime. The review of the telecoms rules will have to look at ways of ensuring a level playing field for players to the extent that they provide comparable services. The level-playing field discussion calls for a balanced assessment: on one hand it is necessary to evaluate to what extent we still need sector-specific rules for electronic communications services and on the other hand to assess which rules, if any, should, in light of public interest objectives apply also to market actors other than traditional telecoms operators. Other technological and economic developments are likely to profoundly change the functioning of the electronic communications sector and to raise new challenges, and may also need to be reflected in revised rules: to facilitate their development, to recognise their effects on the functioning of markets that are currently regulated, or to address new bottlenecks that they engender – the increasing convergence of fixed and mobile networks, the migration to "all-IP" networks, the increasing "virtualisation" of networks, the rise of machine-to-machine (M2M) communications. The changing market and technological environment calls also for the assessment of the current institutional framework. The role of bodies in which the Member States' authorities are themselves represented – such as the Body of European Regulators for Electronic Communications (BEREC) or the Radio Spectrum Policy Group (RSPG) - will need to be assessed against their capacity to contribute to a consistent and predictable regulatory environment supporting the connectivity ambition set out in the Digital Single Market strategy. Potential benefits from a European market with genuinely common rules Although telecom markets have become more integrated, progress is slow and the provision of connectivity to business and consumers remains highly fragmented and divergent across the Union. This is particularly the case for radio spectrum which is a vital building block for the deployment of broadband services. A recent study for the European Parliament assessing the achievements and failures of the current framework has shown that Europe's telecoms sector remains fragmented along national lines. This lack of integration represents a significant missed opportunity. It is estimated (Business communications, economic growth and the competitive challenge, WIK-Consult, January 2013), for example, that the indirect benefits which could be achieved from policies fostering a consistent regulatory approach for business communications alone amount to € 90 bn per annum.
