The European Commission plans to set a new minimum of 25 years for spectrum licenses to be held to boost investment in the sector.

The Commission would be able to adopt binding guidance on conditions of the assignment process such as the deadlines for spectrum allocation and spectrum sharing, according to the documents seen by Reuters.

There would be provisions for member states to voluntarily organise spectrum auctions to award licenses across multiple countries or across the whole EU.

The documents also propose establishing a peer review mechanism to review the measures of national regulators on spectrum allocation.

"Long-term license durations of at least 25 years proposed in this option will increase stability and certainty of investments as well as innovation requirements," the document explains.

Different spectrum bands are used for different services. Spectrum bands have different characteristics, which makes them suitable for different purposes.

By extending the licenses, the Commission hopes that the operators will have more of an incentive to invest in services using their bands.

This investment will be particularly important to providing 5G connectivity, the next generation of cellular network which among other applications is expected to carry the huge increase in internet traffic expected from the Internet of Things.

The proposals will be published in September.

Online services such as WhatsApp are also set to fall under new rules in the announcement as the European Union extends the scope of telecoms regulation.

The services will have to abide by new security and confidentiality provisions, the Financial Times reported.

The new rules will focus on how services such as WhatsApp comply with requests from security agencies and how companies use customer data.

Services that let users dial a phone number online may be affected by the rules currently governing phone use, according to the internal documents.
